Question | Answer |
---|---|
another term for mechanical weathering | physical weathering |
key words for weathering | "breaks down", "wearing down" |
key words for erosion | "moving", "washing away", "carrying away" --anything that causes movement |
key words for deposition | "forming", "drops" |
examples of mechanical weathering | ice wedging, root wedging, glaciers scraping, water breaking down, gravity, animals burrowing |
examples of chemical weathering | rust (oxidation), acid rain, cave formed by dissolved limestone |
another word for rust | oxidation |
How does climate affect weathering? | It affects the rate of weathering and can cause it to happen faster. Tornadoes, lots of rain, lots of snow, and strong winds can cause weathering to happen faster. |
What is root wedging? | when roots of plants break up the earth |
How does ice wedging cause weathering? | The water freezes and thaws, causing the ground to crack. |
What is abrasion? | the grinding away of rock by other rocks |
four agents of erosion | wind, water, ice (glaciers), gravity |
What is runoff? | water that doesn't soak into the ground |
What is deposition? | the dropping of sediments that have been carried by erosion |
What is weathering? | the breaking down of rocks |
What is erosion? | the processes that move sediments from one place to another |
five environments of deposition | marsh, river, delta, barrier island, beach |
