Agents of Erosion
The 4 types of erosion are
Wind, Water, Gravity, Glaciers
Carbon dioxide mixing with water creates
Carbonic acid
What determines the amount of sediment carried in the stream?
Turbulence
Glaciers break up bedrock through the process of _____.
Plucking
This layer of soil contains humus.
A horizon
Breaks down rocks
Weathering
Water mixing with decaying plants creates
Humic Acid
When streams empty into a flat dessert the area is called this.
Alluvial fan
List 3 of the 6 factors that affect how fast a glacier moves.
Slope
Rate of snowfall
Length of winter/summer
Avg temps
Amt of dark glacial debris
Existence of pools of meltwater
Valuable topsoil containing equal parts sand and silt with about half as much clay is called
Loam
Moves rocks to a new location
Erosion
Name 3 of the 5 things that increases the chances of chemical weathering?
Climate, topography, vegetation, the mineral iteself, surface area
Streams that slow down gradually create this.
Well sorted sediment
Mass wasting that moves quickly but only a short distance.
Thick fine-grained strata that is a good base for fertile farmland.
Loess
Places rocks at a new location
Deposition
Underground rocks are brought to the surface by this process
Frost Heaving
Flat land next to a stream bed
Floodplain
All deposits of sediments from glaciers is called this.
Glacial drift
This is the process of forming desert pavements by wind erosion of loose sediments from flat, dry terrain.
Deflation
Caused by plants and animals
Biological Weathering
When physical processes separate rocks into thin layers this occurs.
Exfoliation
This movement allows for larger debris to move along the stream bottom.
Saltation
This fills with mountain water after the glacier melts.
Cirques
Deflation is to desert pavement as ________ is to ventifact.
Abrasion
