| Deflation | wind picks up loose materials high into the air. |
| Abrasion | wind picks up loose materials and pushes it along the ground.The sharp edges of the particles cut away at the rock. |
| Dunes | wind pushes sand up on beaches and it forms a hill. |
| Running Water | water picks up loose particles and carries them downstream. |
| Root-pry | roots grow into cracks in rocks and pry it open. |
| Gravity | pulls rocks down hills.Ex: landslides. |
| Oxidation | oxigen gets into rocks and it reacts with the iron in the rocks and it rusts. |
| Carbonation | carbon dioxide dissolves in to water(usually rain) and forms weak acid which eats some minerals away. |
| Temp. | rocks expand when they get hotter and shrink when they get colder. |
| Frost Action | water seaps into cracks and when it gets colder 0 degrees C the water freezes and it expands which causes the rock to crack. |
| Sulfuric Acid | Sulfure oxide dissolves in rain and makes a acid |
| Plant Acids | weaks acids produced by plants. |
| Erosion | weathered rock moves from place to another. |
| Deposition | deposits made by exfoliation. |
| Loess | many layers of sand deposited in the same area. |
| Runoff | when it rains some of the water goes into the ground and some run off on the ground and takes little bits of soil with it. |
| Drainage System | rills,gullies,streams,rivers. |
| Drainage Basin | area drained by a main area. |
| Delta | soil carried in water sinks to bottom when the water goes into the ocean and slows down. |
| Exfoliation | pieces of rock breaking flat and parrellel to the big rock. |
| River | large stream, main stream. |
| Stream | small river. |
| Gullie | small streams that turn into big streams. |
| Glaciers | large chunks of ice and rocks stick to bottom and it grinds away on the surface. |
| Flood Plains | when rivers flood lots the water goes over its banks and onto large fields and the water soaks into the ground and all the soil in the water settles into the ground. It makes a large fertile field. |
