________ is the mechanical or chemical surface process that breaks rocks into smaller pieces.
What is weathering
100
The surface feature of land is called what?
What is topography
100
T/F Erosion is the wearing away and removal of rock.
What is true
100
Erosion when whater gets into the cracks of the rock, freezes, breaks the pieces of the rock, and washes away loose sediment when it thaws is called what?
What is ice wedging
100
Carbon dioxide and water combine to form what acid?
What is carbonic acid
200
Name the two forms of weathing.
What is mechanical weathering and chemical weathering
200
___________ consists of decomposed leaves, twigs, roots, and other material.
What is organic matter?
200
Name the four factors of soil erosion
What is ice, water, wind, and gravity
200
Which one of these is not an example of mass movement: glaciers, slump, creep, mudflows?
What is glaciers
200
When valley glaciers remove rock from moutain tops, large basins or bowls called ______ are carved out.
What is cirques
300
T/F There are two important forms of chemical weathering: natual acids and Artifical acids.
What is false
300
What is soil?
What is a mixture of weathered rock, organic matter, water, and air
300
______ is a form of erosion that can make pits in rocks and produce smooth polished surfaces.
What is abrasion
300
______ causes mass movement.
What is gravity
300
Define mechanical weathering. Then provide 2 examples of mechanical weathering.
Mechanical weathing is the breaking down of rocks without changing them chemically. Examples: ice wedging and roots from plants
400
Chemical weathering takes place fastest in a _________ climate.
What is tropical (or hot and wet)
400
Name the 5 factors that affect soil formation
What is parent rock, slope of land, climate, time, and organisms
400
What two ways can ice erode rock?
What is ice wedging and glaciers
400
T/F delfation is the erosion of land by water
What is false
400
Define mass movement. Name the four types of mass movement. Then describe one type.
Mass movement is erosion caused by gravity. It includes slump, creep, rock slides, and mud flows. Rock slides involve rock breaking lose from a slope and falling down the slope, breaking apart as it does so.
500
What are the two important causes of mechanical weathering?
What is ice wedging and plants and animals
500
T/F Soil forms by following these steps: Weathing wears down the bed rock, organic matter begins to form, then the organic matter begins to break down the rock and top soil begins to form.
What is true
500
When freezing and thawing cause sediments to move slowly downhill, ______ takes place.
What is creep
500
______ occurs when a mass of rock or sediment moves down hill leaving a curved scar
What is slump
500
Compare and contrast weathering and erosion.
Weathing and erosion both involve the breaking down of rock into smaller pieces. However, erosion involves moving the rock, while weathering keeps the rock in the same location.
