weathering
What is the process by which rocks break down into smaller pieces?
Answer: Weathering
What is deposition?
Answer: The process where sediments settle out of the transporting medium.
What is erosion?
Answer: The process of moving soil and rock from one location to another.
What force pulls objects toward the Earth?
Answer: Gravity
What are glaciers?
Answer: Large masses of ice that move slowly over land.
Name one type of weathering that involves chemical reactions.
Answer: Chemical Weathering
Name a natural feature formed by deposition.
Answer: Delta
Name one agent of erosion.
Answer: Water, wind, ice, or gravity
How does gravity affect the movement of water?
Answer: It causes water to flow downhill.
How do glaciers cause erosion?
Answer: They scrape and carry away rocks and soil as they move.
What type of weathering occurs when water freezes in cracks of rocks?
Answer: mechanical weathering
How does wind contribute to deposition?
Answer: Wind can carry and drop off sand and other materials.
How can animals contribute to erosion?
Answer: Burrowing animals can disturb soil and lead to erosion.
What is mass wasting?
Answer: The downward movement of rock and soil due to gravity.
What is a U-shaped valley, and how is it formed?
Answer: A valley formed by the movement of a glacier.
How does vegetation help in weathering?
Answer: Roots of plants can break rocks apart.
What role do rivers play in deposition?
Answer: Rivers carry sediments and deposit them when they slow down.
What is the impact of deforestation on erosion?
Answer: It increases erosion because there are fewer roots to hold soil in place.
Name a landform created by gravity's effects.
Answer: Landslide
How do glaciers contribute to deposition?
Answer: They leave behind sediments when they melt.
What is the difference between mechanical and chemical weathering?
Answer: Mechanical weathering breaks rocks into smaller pieces without changing their composition, while chemical weathering changes the minerals in the rocks.
Explain how human activities can affect deposition.
Answer: Construction can change natural water flow, affecting where sediments deposit.
Describe how waves can cause erosion along coastlines.
Answer: Waves crash against rocks and cliffs, wearing them away over time.
Explain how gravity influences erosion and deposition.
Answer: Gravity causes materials to move downhill, leading to erosion and deposition in lower areas.
Describe the term "glacial till."
Answer: Unsorted material deposited directly by a glacier.
