Define It
What is the process that breaks down rocks into smaller pieces without changing their composition?
What is Mechanical (physical) weathering?
Which process is being described: wind carrying tiny particles that grind against rock and wear it away? (weathering, erosion, or deposition)
What is weathering.
What can happen to soil and plant life when people cut down large forests?
What is soil washes away more easily; fewer plants grow; loss of nutrients; increased erosion and possible landslides.

What is one way humans can accidentally cause more erosion when they change the land?
What is removing trees (deforestation) so roots no longer hold soil in place, causing more erosion.
What is the term for the process that moves sediment from one place to another by water, wind, ice, or gravity?
What is erosion?
Which process forms a delta at the mouth of a river: weathering, erosion, or deposition?
What is deposition.
Name two kinds of events caused by gravity that move sediment downhill.
What is landslides and rockfalls (also mudflows).
When a glacier flows downhill, what two things does it do to rocks?
What is it breaks off pieces of rock and carries them away.

What do we call the process of putting down or dropping sediment in a new place after it has been moved?
What is deposition?
Which agent caused the natural arches and rounded rock shapes in Utah according to the text: wind, gravity, or plants?
What is wind?
How do beavers change the land where they live?
What is Beavers chew down trees and build dams that reroute rivers and create ponds, changing habitats and landforms.
When a glacier flows downhill, what two things does it do to rocks?
What is it breaks off pieces of rock and carries them away.

What is a landform? Give two examples.
What is a landform is a feature on Earth's surface (examples: mountain, valley, dune, plain).
Which is an example of erosion by ice mentioned in the text?
What is a glacier breaking off pieces of rock and carrying them (glacial erosion).
Describe one way animals other than beavers affect the land, using the examples from the text.
What is Prairie dogs dig extensive burrows that change the prairie landscape (remove soil, create tunnels).
Based on the text, what would you expect to see at the mouth of a river that is carrying a lot of sediment?
What is a delta: sediment piles up and the river branches into smaller channels forming new land.
Name two negative effects of removing forests on local ecosystems mentioned in the text.
What is a loss of soil nutrients, fewer plants and animals, increased landslide risk, and harm to food webs.
Explain in one sentence what biological weathering is and give one example from the text.
Biological weathering is weathering caused by living things (example: plant roots growing into cracks and splitting rock).
Explain in one sentence what biological weathering is and give one example from the text.
What is gradual weathering and erosion; these wear down peaks and round them over long time.
Explain how human actions contributed to the spread of kudzu and one method used today to control it.
What is Kudzu was planted to prevent erosion and spread because it grows rapidly; control methods include mowing, burning, herbicides, and grazing by goats or llamas.
Imagine a coastline with waves hitting a cliff. Describe two changes you could observe over time and name the processes responsible.
What is a cliff being worn away by waves (erosion) and sand being deposited to form beaches or dunes (deposition); possible rockfalls from gravity.
Suggest two actions people or governments could take to reduce erosion and protect forests, based on ideas from the text.
What is replanting and protecting forests, making laws to limit deforestation, using controlled grazing or mechanical removal to control invasive plants like kudzu, and teaching sustainable land-use practices
