100
Freezing and thawing of water causes this type of mechanical weathering to occur
What is Frost Wedging
100
This type of decomposer is responsible for most of the mixing of humus
What is a worm
100
This Horizon consist of clay and other particles of rock but little humus
What is Horizon B
100
This scientific principle tell us that the processes working on the Earth's surface millions of years ago are still working today
What is Uniformitarianism
100
Earthworms add their waste to soil contributing to the formation of this
What is Humus
200
This type of rock particle is second smallest when compared to clay
What is Silt
200
This happens when plant growth is absent to protect soil from water or wind
What is Erosion
200
The texture and particle size of soil determine this
What is Permeability
200
This process breaks down rock and other substances
What is Weathering
200
A long drought in the 1930's combined with farmers removal of this caused the Dust Bowl to happen
What are plants (prairie grasses)
300
Rock worn away by coming in contact with other rock particles is this type of mechanical weathering
What is Abrasion
300
This type of soil is made up of almost equal parts of sand, silt and clay
What is Loam
300
This weather condition causes the details of softer rock like marble to chemically weather
What is Acid Rain
300
When this horizon is exposed on the surface it begins to breakdown into smaller pieces
What is Horizon C (Bedrock)
300
This style of farming changes the type of plants every year to reduce the nutrient loss in soil
What is Crop Rotation
400
These (2) conditions cause weathering to take place most rapidly
What are Hot and Wet
400
Turning over dead weeds and stalks from the previous years crop left in the ground returning nutrients back to the soil is called this
What is Conservation Plowing
400
These two factors are the most important in determining the rate at which weathering occurs
What are Type of Rock and Climate
400
These are three agents of chemical weathering
What are water, oxygen, carbon dioxide, living organisms and acid rain
400
This is also known as Horizon A
