Types of Erosion (3)
- Water
- Wind
- Glacial
Erosion Causes (5)
- Soil erodibility
- Texture
- Overgrazing
- Cutting of trees and removal of vegetation
- Use of pesticides and other chemicals
- occurs when rainfall is low and soil moisture is lowest
wind erosion
no need for transporting mediums, just downward flow
mass wasting
Mass Wasting Factors (4)
- Over steepened Slopes
- Angle of Repose
- Slightly wet unconsolidated materials
- Lack of plants
Mass Wasting Types (8)
- Creep
- Debris flow
- Mudflow
- Earthflow
- Solifluction
- Flow
- Rockslide
- Fall
slowest type of mass wasting
creep
fastest type of mass wasting
fall
has the consistency of wet concrete
mudflow
Mass Wasting Prevention (3)
- Hazard Maps
- Engineering Measures
- Soft Mitigating Measures
Sedimentation Properties (3)
- Roundness and Sphericity
- Sorting
- Size and Velocity
gravel and coarser particles are carried by __________
high energy currents
sand and finer sediments are transported through _____ and _____ action
wind, wave
pollution when silt / clay dominates a body of water
siltation
accumulation of fine particles at the bottom of the body of water
siltation
clarity of water
turbidity
Effects of Excessive Sedimentation (2)
- Corals
- Siltation
