Weathering
The definition of weathering
What is the physical disintegration of rock
The transport of broken down materials
What is the definition of erosion?
The unequal sharing of electrons
Why is water polar?
the draining away of water and substances from the surface of land, building, etc.
What is runoff?
the material on which soil develops
The two different types of weathering
What is chemical and mechanical weathering?
Erosion is the transport of materials while weathering is the breaking down of materials
What is the difference between erosion and weathering?
Other materials that are polar
What materials can water dissolve?
porous, or allowing liquids to pass through
What is permeable?
the top layer of soil
What is the O layer?
The size and shape of the rock or mineral, not the chemical composition
What is the way that mechanical weathering breaks down rocks and minerals?
Wind, water, glaciers, gravity, living things
What are erosional agents?
Cohesion between water molecules allows this property of water
What is surface tension?
holding as much water as possible
What is saturated?
also known as the zone of accumulation
what is the B layer?
In wet and warm climates
In what type of climate is chemical weathering quickest?
The downslope movement of rock, regolith, and soil under the direct influence of gravity
What is mass wasting?
When water freezes, the density decreases
Why does ice float on water?
a layer of soil that has identifiable characteristics produced by chemical weathering and other soil-forming processes
what is soil horizon?
a vertical section through soil showing all of the horizons
What is a soil profile?
Frost wedging
What is the effect of temperature on weathering?
Steep slopes with little to no vegetation
Where is erosion more likely to occur?
The heat required to raise the temperature of the unit mass of a given substance by a given amount
What is specific heat?
layer of rock and soil that is nearly everywhere
What is regolith?
soil that is developed from a parent material in another location
What is transported soil?
