100
The weathering process that physically breaks rock into smaller pieces
What is mechanical weathering
100
Loop-like bends in a river that flows across a wide flood plain are called this.
What is a meander
100
How much air and water soil can hold is determined by this.
What is texture, or particle size
100
The four types of mass movement
What are slump, landslide, mudslide, and creep
100
Two types of glaciers
What are continental and valley glaciers
200
The process of wearing down and carrying away rocks
What is erosion
200
This is caused by a river flowing from an area of harder rock to an area of softer rock, wearing away the softer rock.
What is a waterfall
200
It is in this soil layer that you would find loam rich in humus.
What is Horizon A
200
The agent that causes mass movement
What is gravity
200
The contents of a till
What are clay, silt, sand, gravel, and boulders
300
Soil formation begins with the weathering of this.
What is bedrock
300
Moving water the flows over land, causing erosion of the land.
What is runoff
300
Nearly equal amounts of silt, clay, and sand make up this type of soil.
What is loam.
300
The process that builds up deltas and alluvial fans, creates oxbow lakes, and sandbars.
What is deposition
300
The formation created when stranded ice blocks left behind by continental glaciers melted
What is a kettle
400
The weathering process that includes water, oxygen, carbon dioxide, and acid rain.
What is chemical weathering
400
The process in which groundwater causes erosion
What is chemical weathering (carbonic acid)
400
Earthworms, by adding their waste to soil and dying and decaying in the soil, help with the formation of this.
What is humus
400
The process through which wind causes erosion - wind picks up and moves particle
What is deflation
400
A ridge of till located at the farthest point reached by a glacier
What is a morraine
500
Geologists make inferences about the processes that shaped the Earth's surface based on this principle.
What is uniformitarianism
500
5 main factors that affect the amount of runoff in an area
What are: amount of rain, vegetation, type of soil, shape of land, human usage
500
Processes that change a rock into soil, starting with abrasion and ending with soil. (pg. 51)
What are: abrasion - weathering (mechanical or chemical) - decomposition - addition of humus - soil
500
Three types of soil conservation.
What are contour plowing, crop rotation, and conservation plowing.
