Weathering
What type of weathering involves freezing and thawing of water in cracks?
What is frost wedging?
Name the four main agents of erosion.
What are water, wind, ice (glaciers), and gravity?
What is deposition?
What is the dropping or settling of sediments?
This landform is carved out by a river over millions of years.
What is a canyon?
The breakdown of rocks into smaller pieces.
What is weathering?
This type of weathering changes the chemical composition of rocks
What is chemical weathering?
This agent of erosion forms U-shaped valleys.
What is a glacier (ice)?
What landform is created at the mouth of a river due to deposition?
What is a delta?
Sand dunes are formed primarily by this process.
What is wind deposition?
The movement of sediment from one place to another.
What is erosion?
What mineral in rocks reacts with oxygen to form rust?
What is iron?
Which erosion agent is most active in deserts?
What is wind?
When a river floods and drops sediments across a wide area, it forms this.
What is a floodplain?
Which landform forms from glacial deposition?
What is a moraine?
A slow downhill movement of soil and rock caused by gravity.
What is a creep?
Tree roots growing into rock and breaking it apart is an example of what?
What is biological (mechanical) weathering?
What is it called when gravity moves rocks downhill without water, wind, or ice?
What is mass wasting?
What happens to sediment when the energy of water or wind decreases?
What is it gets deposited.
What is the difference between a delta and an alluvial fan?
A delta forms at water bodies; an alluvial fan forms on land.
Wind blows loose sediment away, leaving behind heavier rocks—this erosion process is called what?
What is deflation?
Which type of weathering would acid rain speeding up limestone breakdown be?
What is chemical weathering (carbonation)?
What are two features formed by river erosion?
What are canyons and meanders?
What cone-shaped landform is created when a stream slows quickly at the base of a slope?
What is an alluvial fan?
Which landform shows evidence of both erosion (cliff) and deposition (beach)?
What is a coastal landscape?
The Earth system that includes rocks and landforms.
What is the geosphere?
