100
Breaking rock into smaller pieces without changing the mineral composition.
What is mechanical weathering?
100
The part of Earth's surface that supports the growth of plants.
What is soil?
100
The upper level of the zone of saturation.
What is the water table?
100
The land area that contributes water to a stream.
What is a drainage basin?
100
A thick ice mass that forms over hundreds or thousands of years.
What is a glacier?
200
The breakup of rock caused by the expansion of freezing water in cracks and crevices.
What is frost wedging?
200
Mineral matter, Organic matter (humus), Water, & Air
What is the composition of soil?
200
The ability of water to move underground.
What is permeability?
200
The slope or steepness of a stream channel.
What is gradient?
200
A type of glacier that slowly advances down mountain valleys originally occupied by streams.
What is valley glacier?
300
Reduced pressure on igneous rock causing it to expand and exfoliate its top layers. Stone Mt. is an example of this.
What is unloading?
300
This refers to the different sized particles of soil.
What is soil texture?
300
The percentage of rock that consists of pore spaces that hold water.
What is porosity?
300
The course the water in a stream flows.
What is stream channel?
300
The two ways glaciers move or flow.
What is plastic flow and basal slip?
400
The transformation of rock into one or more new compounds through weathering.
What is chemical weathering?
400
Parent material, time, climate, organisms & slope
What are factors controlling soil formation?
400
A flow of groundwater that emerges naturally at the surface. This is where the water table intersects the ground surface.
What is a spring?
400
The maximum amount of sediment (load) a stream can carry.
What is capacity?
400
Material deposited directly by a glacier.
What is till?
500
The two most important factors that determine the rate at which rock weathers.
What is rock characteristics and climate?
500
Zones or layers of soil.
What are soil horizons?
500
Landforms that are shaped by groundwater dissolving the surrounding rock.
What is karst topography?
500
Deltas, meanders, oxbows, waterfalls and levees.
