Weathering
This type of weathering is the breakdown of large rocks into fragments by physical forces.
What is physical weathering?
These structures occur as underground cavities when erosion happens beneath the earth's surface.
What are caves?
This formation results when running water carves a channel in the ground that cannot be repaired by ordinary cultivation.
What is a gully?
This is a type of physical weathering occurs when rainwater or melted ice soaks into tiny cracks of a rock and freezes.
What is ice wedging?
This is the material carried by a stream.
What is a load?
This formation results when a river on a soft, flat floodplain develops curves and twists, creating a course that bends like a snake.
What is a meander?
This weathering process involves the breaking or peeling away of rock layers.
What is exfoliation?
This process occurs when eroded rock fragments are eventually set down in a new location.
What is deposition?
This is formed by a buildup of calcium carbonate deposited by water droplets.
What is dripstone?
This process involves the oxygen in air and water reacts with minerals like calcium, magnesium and iron to form new compounds.
What is oxidation?
This consists of a relatively large stream and any smaller streams that flow into it.
What is a drainage system?
This formation is fan or triangular shaped deposit extending from the mouth of the river into the sea.
What is a delta?
This is the main agent of chemical weathering, which is slightly acidic in its natural environment.
What is water?
This is the largest drainage basin in the United States, covering about half of the country.
What is the Mississippi River drainage basin?
This crescent-shaped body of water is created when a meander is bypassed and becomes cut off from the rest of a river.
What is an oxbow lake?
