100
The soil horizon that contains rock fragments, air, water and organic remains.
What is the topsoil (A-horizon)?
100
Form when carbonic acid in groundwater dissolves limestone leaving an opening in the rocks.

100
Water that soaks into the ground.
What is groundwater? (infiltration)

200
A stream that flows directly into a cave system.
What is sinking (disappearing) stream?
200
Earth materials whose pore space is filled with water.
What is aquifer?
200
Fan-shaped deposit where a stream flows onto dry land.
What is alluvial fan?
300
A curved feature of mature or old streams that form when a meander is cut off during a flood stage and becomes silted up on the ends but filled with water.

A funnel shaped depression created by the collapse of a cave.
What is a sinkhole?
400
Forms when a well is pumped, especially if it is pumped rapidly.
What is a cone of depression? (lowering of the water table)
400
Inside of a meander where deposition is occuring.
What is a point bar?
500
The type of material most visibly carried by a river in flood stage.
What is suspended load?
500
Soil that has space to allow water to flow through.
What is permeable soil? (aquifer)
500
Factories, cars, houses, septic leaks, and animals.
What are sources of pollution of a karst aquifer?
500
A system used to dispose of waste water from houses by filtering through the ground.
What is septic system?
