erosion & deposition
erosion & deposition vocabulary
| Question | Answer |
|---|---|
| the process by which natural forces move weathered rock & sediment | EROSION |
| the process by which sediment settles out of the water or wind & is deposited in a new location, changing the shape of the land | DEPOSITION |
| gravity, running water, glaciers, waves, wind | AGENTS OF EROSION |
| the three processes that, together, wear down and build up Earth's surface | WEATHERING, EROSION & DEPOSITION |
| a process of erosion that moves rock & sediment downhill; caused by gravity | MASS MOVEMENT |
| rock & soil slide quickly down a steep slope | LANDSLIDE |
| rapid downhill flow of a mixture of water, rock & soil | MUDFLOW |
| a mass of rock & soil suddenly slide down a slope in one large mass | SLUMP |
| the very slow downhill movement of rock & soil | CREEP |
| the major agent of erosion that has shaped Earth's surface | MOVING WATER |
| water that moves across the land because it is not absorbed into the soil | RUNOFF |
| a feature that can significantly decrease the amount of runoff in an area | VEGETATION |
| a feature that significantly increases the amount of runoff in an area | DEVELOPMENT |
| the land area from which a river & its tributaries collect water (aka drainage basin) | WATERSHED |
| tiny grooves in soil caused by runoff | RILLS |
| large grooves or channels that carry runoff after heavy rain | GULLIES |
| channels in which water is continually flowing down a slope | STREAMS |
| large streams | RIVERS |
| formed by steep slopes that erode rapidly due to a fast-moving river | V-SHAPED VALLEY |
| formed by a river flowing over an area of hard rock that resists erosion that is supported by layers of soft, easily eroded rock | WATERFALL |
| looping bends of a river | MEANDERS |
| crescent-shaped body of water formed from a meander cut off from a river by deposition | OXBOW LAKE |
| landform made of sediment deposited where a river flows into an ocean or lake | DELTA |
| a wide, sloping deposit of sediment formed where a stream leaves a mountain range | ALLUVIAL FAN |
| the breaking down of rock into sediment | WEATHERING |
| the cause of mass movement | GRAVITY |
| the 5 agents of erosion | MOVING WATER, GRAVITY, GLACIERS, WAVES, WIND |
| THE major agent of erosion is __, which includes __ & __. | MOVING WATER; RIVERS & RUNOFF |
| landforms/features produced by runoff | RILLS, GULLIES, STREAMS, RIVERS |
| for deposition to occur, the agent of erosion must __ | SLOW DOWN |
| Of the following agents of WEATHERING, which is NOT also an agent of erosion? gravity ice (glaciers) living organisms (animals, plants) moving water wind | ORGANISMS are NOT agents of erosion |
| The following are agents of EROSION that ALSO weather rock: gravity, glaciers, moving water, wind. How do these agents BREAK rock? | by ABRASION |
| landforms created when water in a river slows down | OXBOW LAKE, DELTA, ALLUVIAL FAN |
| landform that protects coastlines from waves & severe storms | BARRIER ISLAND |
| source of material (sand, etc) that makes up most beaches | RIVER SEDIMENT DEPOSITED INTO THE OCEAN |
| The weakest agent of erosion is __, except in areas that have __. | WIND; LITTLE VEGETATION |
| ridges of sediment deposited by glaciers | MORAINES |
| The size of sediment carried by wind & water increases as __. | THE SPEED OF THE WIND & WATER INCREASES |
| landform produced by glacial erosion | U-SHAPED VALLEY |
| 3 landforms produced by wave erosion | SEA CAVE, SEA ARCH, SEA STACK |
| landforms produced by rivers carrying away sediment | MEANDER, WATERFALL, V-SHAPED VALLEY |
| key distinction between creep & all other types of mass movement | SPEED |
| the process by which glaciers carry sediment, rocks, boulders | PLUCKING |
| Georgia's St Simons, Jekyll, & Cumberland are examples of __ | BARRIER ISLANDS |
| The continuous movement of sand due to longshore drift is interrupted/altered by __. | JETTIES |
| What is a remedy to the runoff produced by certain kinds of development? | GREEN ROOFING |
