Weathering/Erosion
Erosion & Deposition - Water & Wind Neumeyer
| Question | Answer |
|---|---|
| Stream | Active water channel that erodes & transports sediment |
| River | Forms on a steep mountain slope |
| What are some features that are formed when rivers flow off and from mountains | Waterfalls, floodplains, meanders, oxbow lakes, & delta |
| Groundwater | Underground water that can cause erosion through a process of chemical weathering forming caves |
| Waves | Shapes coast lines through erosion by breaking down rock & transporting sand & other sediment, erode land by impact of great force and abrasion or grinding away at shore |
| Wind | Causes erosion by deflation |
| What force is more responsible for shaping the Earth. Water or wind | Water force |
| Waterfalls | Occurs where a river meets an area of rock that erodes SLOWLY |
| Flood plains | Flat, wide, area of land along a river that is often covered when the river overflows during a flood |
| Meanders | Loop-like bend in the course of a river and becomes more curved over time |
| Oxbow lakes | A meander that has been cut off from sediments, being positive & damming up the ends |
| Delta | Sediment is deposited where a river flows into an ocean or lake and builds up a landform |
| Stalactites | Formed when deposits in dripping groundwater that hang on the roof of a cave |
| Stalagmites | Formed through deposits that build up cone shapes on the cave floor |
| Deflation | The process by which wind removes surface materials & abrasion |
| Loess | A crumbly wind-blown deposit of silt and day |
| Abrasion | Grinding away something |
| When/where are water a major agent of erosion (4) | Streams, rivers, beaches & underground |
| Dunes | Wind-blown sand |
| What are some common types of windblown deposits (2) | Dunes and loesses |
