What is mass movement and what causes it? Mass movement causes regolith and rock to move down-slope where sooner or later the loose particles will be picked up by another transporting agent and eventually moved to a site of deposition such as an ocean basin or lake bed
What are the four types of mass movement? Mass movements can be divided into four main classes. These are Falls, slides, creeps and flows.
What is the major agent that has shaped Earth’s surface? Sea waves that erode the Earth around coastal lines.
What is runoff? The draining away of water (or substances carried in it) from the surface of an area of land, a building or structure, etc.
What is rill? A small stream
What is Gully Eroded gullies into (land) by water action.
What is Stream? A small, narrow river
What is river? A large natural stream of water flowing in a channel to the sea, a lake, or another such stream
What land features are created by water erosion? Their are caves, valleys, oxbow lakes, water falls, canyons, and meander rivers
What is valleys? A low area of land between hills or mountains, typically with a river or stream flowing through it
What is caves? A large underground chamber, typically of natural origin, in a hillside or cliff
What is meander rivers? A meander, in general, is a bend in a sinuous watercourse or river. A meander is formed when the moving water in a stream erodes the outer banks and widens its valley and the inner part of the river has less energy and deposits what it is carrying.
What is oxbow lake? U shaped lake cut off by river
What is canyons? A deep gorge, typically one with a river flowing through it
What is water falls? A cascade of water falling from a height, formed when a river or stream flows over a precipice or steep incline
What is Karst Topography? Is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone
What is till? A sediment consisting of particles of various sizes and deposited by melting glaciers or ice sheets
What is moraine? A mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity
What is Drumlin? A low oval mound or small hill, typically one of a group, consisting of compacted boulder clay molded by past glacial action
What is Kettle Lake? A kettle is a shallow, sediment-filled body of water formed by retreating glaciers or draining floodwaters
What land features are made from wave erosion? The 3 land forms created by wave erosion sometimes called coastal erosion are headlands and bays, cliffs and wave cut platforms and finally caves, arches, stacks and stumps.
What is Cliffs? A steep rock face, esp. at the edge of the sea
What is caves? A large underground chamber, typically of natural origin, in a hillside or cliff
What is beach barrier? a sand ridge that rises slightly above the surface of the sea and runs roughly parallel to the shore, from which it is separated by a lagoon
What is sand bar? a long, narrow sandbank, esp. at the mouth of a river
What is spit? A spit or sandspit is a deposition landform found off coasts
What is the difference between a sand dune and a loess? when the wind blows, it lifts and transports the sand and sediments. They form in a low hill like structures known as sand dunes. when the grains of sand are very fine and light, the wind can carry it over very long distances. It is known as a loess.
The process where wind picks up sediment and moves it is called plucking
What are arches? A curved symmetrical structure spanning an opening and typically supporting the weight of a bridge or roof
