This is a vertical sequence of soil layers
Soil Profile
Breakdown of rock into smaller pieces.
Weathering
This process strips the outer layer of rock away.
Exfoliation
What is the difference between reel erosion and gully erosion?
Reel erosion is small channels cut by running water down a slope while gully erosion forms trenches
How would you classify soil that is 60% sand, 30% silt, and 10% clay?
Sandy Loam
How does climate influence the rate of weathering?
Different types of weathering occurs better in different regions. Water is a major agent of erosion so more precipitation can increase weathering.
What is the O horizon composed of?
Leaf litter and humus
What happens when a river enters a larger body of water.
The water slows down and deposits large amounts of sediment
What climate does mechanical weathering happen best in?
Cool and dry
What is acid rain?
A rain that has a pH below 5.6
How do living things impact weathering and erosion?
Trees may break up rock, humans move soil when building, animals burrow holes
How does slope effect erosion?
Material can move down a slope and expose more rock more quickly.
In the northern hemisphere, what side of the hill sees more sunlight?
South
What area would wind be a major erosional agent.
desert
True or false: Wind can work against gravity?
True
What role does surface area play on weathering?
The more surface area the more weathering can occur
