Types of weathering
Breaking rock into smaller pieces without changing composition
physical
List the climate factors that promote the most chemical weathering
warm and moist
Water that is stored in pore spaces within rock and soil is called
groundwater
This is the process by which water falls from the sky
precipitation
The rate at which water flows through rock or soil
permeability
An example of this kind of weathering would be oxidation
chemical
Draw the relationship between exposure and weathering
As exposure increases, weathering increases (arrow going up, direct relationship)
Draw the relationship between the amount of infiltration and the amount of runoff
As one increases, the other decreases, arrow pointing down, indirect relationship
This is the process by which water vapor enters the atmosphere through PLANTS
Transpiration
Draw the relationship between porosity and grain size
STAYS THE SAME
This is what happens when liquid water freezes and expands, breaking apart a sample of rock
frost wedging
List the climate factors that would promote the most amount of physical weathering
cold and moist
This kind of soil has a composition that matches that of the parent bedrock
Residual
Name one way to speed up the process of evaporation
heat, surface area, wind, dry air
What is one factor that could INCREASE porosity
Less packing, more sorted, rounder shape
While taking a walk, you notice that the side walk is uneven, filled with bumps and cracks. This only seems to happen where trees are nearby. This is an example of what kind of physical weathering?
root wedging
Sediments that are smaller in size will weather faster because they have more ______________
surface area
New York state has this kind of soil, brought in by glacial movement
transported
This process produces clouds
condensation
Compare the permeability for a sample of mixed sediment and a sample of sorted sediment
This rock type is susceptible to acid rain, making it a common area for the formation of caves and caverns
Limestone
A rock layer that is the most resistant to all kinds of weathering is likely made of this mineral
quartz
Describe the effect on the water table if infiltration increases
Water table will go up
After water precipitates back to the ground, list the TWO possible movements of water
infiltration or run off
A homeowner wants water to flow quickly through the ground surrounding his home, and to have as little retention as possible in order to avoid flooding. What size particle should he use? (clay, silt, sand, pebbles)
Pebbles!
