The slump that destroyed Thistle, Utah, by creating an earthen dam that flooded the area A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope.  M.. Describe the process of slumping. 5 July 2020 / in AQA GCSE Geography, Coasts, Mass Movement / by Anthony Bennett. The soft boulder clay holds rainwater and run-off. Waves erode the base of the cliff creating a wave-cut notch. The clay becomes saturated and forms a slip plane. The weight of the saturated cliff causes it to slump Slumping: involves a whole segment of the cliff moving down-slope along a saturated shear-plane. Soil Creep : the slowest of downhill movements, occurring on very gentle and well-vegetated slopes. Although material may move by less than 1 cm a year, its results can be seen in step-like terracettes on hillsides Slump, in geology, downward intermittent movement of rock debris, usually the consequence of removal of buttressing earth at the foot of a slope of unconsolidated material. It commonly involves a shear plane on which a back-tilting of the top of the slumped mass occurs. The plane is slightl
Slumping / Rotational Slip. Cliffs formed from boulder clay, material deposited by glacial periods, are susceptible to high rates of coastal erosion. The Holderness Coast is an example of a coastline formed from boulder clay and is the fastest eroding coastline in Europe. The soft boulder clay is quickly eroded through hydraulic action and abrasion.. Slumping. Slumping occurs when material moves along a curved path. The technical term is 'rotation' so slumping is also known as 'rotational slip' or 'rotational slump'. In the photograph the path of the slump is highlighted by the red line. It occurs mainly in soft and uniform rocks such as silts and clays, and can be triggered by. Other articles where Rockfall is discussed: mass movement: of solid rock, known as rockfalls; several types of almost imperceptible downslope movement of surficial soil particles and rock debris, collectively called creep; the subsurface creep of rock material, known as bulging: the multiplicity of downslope movements of bedrock and other debris caused by the separation of a slope sectio
Rotational slumping. With rotational slumping, heavy rain is absorbed by unconsolidated material making up the cliff (often glacial till, or boulder clay). The cliff face becomes heavier and eventually it separates from the material behind at a rain-lubricated slip plane Coasts are shaped by the processes of erosion, transportation and deposition. Waves are the main reason for coastal change. Waves are created as wind blows over the water causing friction; this causes the water to start to move in a circular orbit. The amount of energy is dependent on the wind speed, the length of time the wind has been blowing.

This is the movement of material along a coastline. Sediment can be moved by 4 basic processes: Traction - where large stones are rolled along the sea bed Saltation - where stones are bounced along the sea bed in a hopping motion Suspension - where fine material is held within the water mass Solution - where rocks and minerals are dissolved within the water The flat rock symbol on the seaward side of the coastline indicates a wave-cut platform at 669421. (BBC Bitesize) Depositional landforms. When water loses its energy, any sediment it is carrying is deposited. The build-up of deposited sediment can form different features along the coast namely: beaches, sand dunes, spits and bars. Beache cliff in place and prevent cliff material from slumping and sliding off. Another method can be to drain any excess water from the cliff. This will prevent water from flowing along planes of weakness which can lead to rock sliding and sediment sliding to the base of the cliff. It will also limit the likelihood of liquefaction which can cause.
BSL Geography Glossary - Suspension - definition. Definition: Suspension is a method of transporting very fine sediment in a river. The sediment is probably eroded from larger rocks upstream and is then carried in the water. When the sediment is deposited from the water it is known as silt. About Us . Landslides and rockfalls are examples of very sudden movements of this type
Mass movement (blockfall, rotational slumping, landslides) is important on some coasts with weak and/or complex geology. Mass movement is the downslope movement of material (rock and soil) under the force of gravity.It is the umbrella term for a wide range of specific movements including landslide, rotational slumping and blockfall . Currents are basically of two types in geography:- 1. Ocean currents Ocean currents are continuous, horizontal movement of seawater in a definite direction from one place to anoth.. Rockfalls occur on slopes exceeding 400. Blocks at the top become loose and fall vertically down the free face (90 degrees) due to gradual weathering processes such as freeze thaw and/ or tectonic activity. Weathered rock at the foot of the slope (scree or talus) at a 45 degree angle and is a boulder controlled concave slope

Slumping (also landslips) Slumps occur in weaker rocks and involve some rotational movement. Slumping can occur after heavy rainfall or earthquakes Back tilted slopes Large blocks break away Sliding surface is concave Soft boulder clay cliffs can be undercut by the sea and slumps are common. 13 Sliding and slumping are two of the distinct mass wasting processes, where the loose and unconsolidated materials falls downward under the influence of gravity. In case of sliding, the materials slides along an plane , whereas, in case of slumping, the loose materials falls down along a curved surface , which slowly results in the rotational.
Sub-aerial procedures additionally help the pace of erosion of coasts. Sub-aerial procedures allude to the procedures of weathering and mass development. Weathering is the separating of rock in situ. It tends to be separated into mechanical and synthetic weathering. Mechanical weathering alludes to physical procedures like freeze-defrost.

This mix is structurally weak since the less resistant rock is prone to slumping and saturation, and so slides over the more. Wave Cut Notch. This is simply a groove, notch or indentation formed along the base of a cliff when it is undercut by the sea. It occurs where the waves break against the cliff and where erosion is most powerful. The photograph shows a wave cut notch being formed at the base of a chalk cliff. The waves can erode only the parts of the cliff that.

Katabatic wind (from the Greek: katabaino - to go down) is the generic term for downslope winds flowing from high elevations of mountains, plateaus, and hills down their slopes to the valleys or planes below. Katabatic winds exist in many parts of the World and there are many different names for katabatic winds depending where they are located and how they are formed Sliding is a synonym of slumping. As verbs the difference between sliding and slumping is that sliding is while slumping is . As nouns the difference between sliding and slumping is that sliding is the motion of something that slides while slumping is the result of a slumping movement, like that of a mountain.

Geography in the News 9. Geography in the News has been created to encourage students to read more widely, examining synoptic links and keep up to date with geography-related news. It has been developed to be given to students as homework and includes differentiated activities for them to complete A fault is a fracture in rock where there has been movement and displacement. When talking about earthquakes being along fault lines, a fault lies at the major boundaries between Earth's tectonic plates, in the crust, and the earthquakes result from the plates' movements. Plates can slowly and continuously move against each other or can build up stress and suddenly jerk Carbonation and dissolution can occur when slightly acidic water comes into contact with bedrock along the river valley. This can affect the landscape by making valley sides less stable and steeper. Temperature also affects river processes. During winter temperatures can fall below freezing, particularly at night and in upland areas Mass movements. This is where land movement at a range of speeds results in destruction of property and/or loss of life. It is often triggered by human activity. In its broadest sense it is the movement down slope of any weathered material ( regolith) under the influence of gravity. The type of movement is influenced by
Attrition is the process where pieces of rock are transported through water and wear down the shore bed over time as a result of friction. Gravel or other small stones are often carried through a current and then come into contact with the sides and bottom of the water body. A secondary effect of attrition is the breaking or refining of small. A mass development alludes to the development of material downslope affected by gravity. They can be quick occasions, for example, avalanches and rockfalls or they can be moderate processes, soil creeps. A typical kind of mass development at coasts is rotational droops. Droops happen because of a mix of components - Email us email@example.com Remember there is also BBC Bitesize for general GCSE revision. Your exam board is OCR B. Good luck! which is lying on top of Chalk. This mix is structurally weak since the less resistant rock is prone to slumping and saturation, and so slides over the more resistant chalk - like a gooey. In some practical soft soil engineering, the excess pore water pressure of soil will continue to rise and the effective pressure will reduce even the load is constant, which is the result of soil creep.Therefore, the ground should be treated firstly when we construct the structure on soft soil ground to improve the drainage condition of soil, which can avoid the shear creep failure

Soil creep - Particles of soil slowly move down the sides of valleys due to gravity. Slumping - The river erodes the valley sides making them steeper and increasing the downward movement of material. Heavy rainfall can trigger this movement. The gadget spec URL could not be found
The answer is C. Permeable rocks are the rocks that let water pass through it. These rocks are usually made of carbonates.They have poreslarge enough to allow water molecules to pass through them. Permeable rocks are usually soft and break easily Weathering. Weathering is the breakdown of rocks at the Earth's surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological When rocks smash and collide into each other. Destructive waves have enough power to carry rocks and sand in them, being hurled at the cliff with the waves, scratching and scraping the rock surface. Can happen a lot in high-energy storm conditions. 13 of 40 Coastal zones are dynamic areas of the earth that experience the influence of both marine and atmospheric activities, also known as coastal processes. These processes involve different events that build-up, breakdown, and transport materials in these coastal zones. Waves, wind, and tides for example impact these coastal areas and change their. Zambia country profile. Zambia, unlike most of its neighbours, has managed to avoid the war and upheaval that has marked much of Africa's post-colonial history, earning itself a reputation for.
Mudflows. Mudflows occur on very steep slopes along the coastline. Where there is limited vegetation to bind the soil together and the ground is very saturated heavy rain can produce sheet flow over the upper cliff surface. The soil continues to be lubricated and it eventually flows over the cliff face and down onto the shore at a fast speed There are various factors which increase the likelihood and rate of different types of Mass Wasting: - Steepness of slope gradient, the steeper the slope, the greater the influence of gravity on particles - Rock structure, bedding planes and faults can increase vulnerability to movements (see slide above - BBC Bitesize - S Cool Geography - Geoguessr - Google Maps - Gapminder - World Atlas - Earthtime.org - National Geographic - SchoolTwitter: @BCGeogDept - Our Place by Mark Cocker - Adventures of a young naturalist by David Attenbrough - Prisoners of Geography by Tim Marshall - Population and Development - Tim Dyson - Factfulness by Hans Roslin Mass movement in river valleys. Mass movement is the down-slope movement of material under gravity. Slides and slumps are examples of mass movement that can occur in river landscapes. In slides, material moves in a straight line, whereas slumping moves with rotation. When a river erodes the base of a valley side it can cause undercutting
Sub-aerial processes - mass movement. Mass movement is the movement of material downslope as the result of gravity. This can be a slow process in the case of soil creep or fast in the case of rockfalls. Water commonly acts as a lubricant in mass movement BBC Bitesize - Higher Geography - Impact of strategies to reduce inequalities - Revision 2 2015 In-text: (BBC Bitesize - Higher Geography - Impact of strategies to reduce inequalities - Revision 2, 2015 ; Costs and benefits of Fairtrade activities - BBC Bitesiz . Fairtrade. Our Fairtrade resources for primary schools include an updated version. Carbonation . Carbonation occurs when rain, which is naturally slightly acidic due to atmospheric carbon dioxide (CO 2), combines with a calcium carbonate (CaCO 3), such as limestone or chalk.The interaction forms calcium bicarbonate, or Ca(HCO 3) 2.Rain has a normal pH level of 5.0-5.5, which alone is acidic enough to cause a chemical reaction. Acid rain, which is unnaturally acidic from.
This effect can occur in the form of intense rainfall, snowmelt, changes in ground-water levels, and water-level changes along coastlines, earth dams, and the banks of lakes, reservoirs, canals, and rivers. Landsliding and flooding are closely allied because both are related to precipitation, runoff, and the saturation of ground by water Latitude and longitude - Atlas skills - KS3 Geography Revision - BBC Bitesize. Geographers need to know how to use and interpret maps and atlases. In order to be able to use these as a source of information, they need a range of skills Where rotational movement occurs, a process sometimes referred to as slumping, a curved rupture surface is. What is weathering? Weathering is the break down of rock in situ by the action of rainwater, extremes of temperature, and biological activity.. What is mechanical weathering? Mechanical weathering is the breakdown of rock without changing its chemical composition. This means the rock breaks up without its chemical makeup changing. Freeze-thaw weathering is the main type of mechanical. Slumping/Rotational slips. Here, water can build up in soils and add weight to it. The material moves down slope along a curved surface, leaving behind an exposed scarp face below the head of the slump, and producing a hummocky toe at the foot. Rock falls. Here, large and small fragments of rock are continually weathered and eroded until they.
