Type of Weathering
The definition of weathering.
What is breaking down large rocks into smaller pieces?
A solid sheet of ice that flows.
What is a glacier?
This occurs when water gets into the cracks in a rock and freezes.
What is frost wedging? will accept erosion by ice
When chemical weathering occurs, a ________ substance is made.
What is new?
This is what biological means. You are a biological organism, so are plants and animals.
What is alive/living?
This type of weathering breaks down rocks through changing the substance, such as rusting.
What is chemical weathering?
The definition of erosion.
What is the movement of sediments, break down of earth (land)
When water continues to run between two steep sides of earth, a ____________ is likely to form.
Will accept canyon, valley, or ditch/gully
When Iron and oxygen combine, this is made.
What is rust?
When these grow into cracks in rocks, and continue to grow, the crack grows.
What are plant roots?
This type of weathering occurs when rocks are broken down without changing the substance.
What is physical weathering?
This type of moving water can carry more sediments for longer distance. (is it fast or slow)
What is fast moving water?
This occurs when wind blown sand weathers rocks.
What is abrasion?
Rust is the product of this process.
What is oxidation?
True or False: Plants cannot break down rocks.
What is false?
Occurs when sediment that has eroded is dropped in a new location.
What is deposition.
This happens when soil, sand, and rocks flow downhill suddenly, due to gravity.
What is a landslide?
When this changes drastically, rocks crack. Think about extreme cold/ extreme heat
What is temperature?
This is how plants break down rock chemically.
What is by producing acid? will except puts liquid on rock that breaks apart or damages
This is how animals can cause weathering.
What is by burrowing? will accept dig, make a hole
When rocks are weathered, it creates this.
What is sediment?
This is when glaciers melt and drop the sediment they were carrying.
What is glacial drift? will accept slide or glacier erosion
List 3 types of physical weathering.
What is abrasion, frost wedging, temperature change, and exfoliation?
When oxygen and water combine with pollution in the air, this forms
What is acid rain?

How could an human cause erosion?
Answers will vary.
