Weather/Erosion
Weathering & Erosion
| Question | Answer |
|---|---|
| Define Weathering: | The chemical and physical process that break down rock at the Earth's surface |
| Define Erosion: | The movement of rock and mineral grains from one place to another |
| What are the 3 main types of weathering? | mechanical, chemical, biological |
| What are 5 things that cause erosion? | wind, water, ice, gravity, plants |
| Landslide: | Mass movement; rock and soil slide quickly down a steep slope |
| Sand Dunes: | Wind; a deposit of wind blown sand |
| Waterfall: | Water; steep slopes erode rapidly from fast-flowing river |
| Desert Pavement: | Wind; smaller sediments are blown away and remains are large and heavy |
| Sea Stack: | Waves; waves hit rocky coast repeatedly causing erosion in rock |
| U-Shaped Valley: | Glacier; flowing glacier scoops out a U-shaped Valley |
| Alluvial Fan: | Water; a stream flows out of a mountain becoming wider. Water slows and sediments are deposited in Alluvial Fan |
| Moraine | Glacier; a glacier deposits mounds of till. Moraine is made up of sand, sediment, and boulders |
| Mechanical Weathering: | The physical break up or desintigration of rocks caused by gravity, temperature change, frost wedging, growth of plants, animal actions, abrasion (ice, water, wind, gravity) |
| Chemical Weathering: | Chemicals present in the Earth's surface and atmosphere, can be dissolved in water: water, oxygen, carbon dioxide, living organisms, acid rain |
| Biological Weathering: | Living organisms can break down rocks: plants, animals, bacteria, fungus, plant roots |
