4. After it rains and you go outside to play, you might notice a lot of small rocks and dirt at the bottom of a hill. This is because erosion took place. The water washed the smaller material down the hill. example
5. The processes that change the character of rocks at or near the Earth's surface Weathering
6.
7. Chemical Weathering Rock Decomposition Rocks are exposed to water and gases Change chemical compounds- form new rocks Second type
8. A large river of ice that moves very slowly. glaciers
9. While glaciers move slowly, they carve out the ground. The carving makes valleys. Making of valleys
10. A mountain that opens down into a pool of molten rock below Earth’s surface. volcanoes
11. Plates under Earth’s crust move apart Movement causes friction Friction causes pressure build up High pressure causes a volcanic eruption How they work…
13. Shaking at the surface of the Earth because of movement underground along a fault line/volcanic activity. earthquakes
14. Determines size of an earthquake Uses seismic waves - A wave that travels through the Earth Richter magnitude scale
15. 2.9 and lower Not felt 3.0-4.9 Felt but little damage 5.0-10 Felt and a lot of damage Richter magnitude scale
16. Rocks and other material sliding down a mountain or cliff. landslides
17. Rain- adds weight Erosion- base is removed Earthquakes- loosens material Volcanic eruption- flowing lava Humans: Mining Deforestation causes
