What is the formation (man made or natural) that can keep a stream from overflowing its banks?
Levee.

Why are there different colors/types of sand on different beaches?
They are made of tiny pieces of different types of rock.

400
What are the five main soil conservation techniques?
Contour plowing, Terracing, No Till Farming, Crop Rotation, and Cover Crops.
400
What are the three factors that determine stream erosion?
Gradient, discharge, and load.
400
What do you call the deposit of sediments at the end of a river into the sea?
Delta.

What are four of the main features left by wave erosion along a coastline?
Sea stack, sea arch, sea cave, headland, beaches.
500
What are two examples of Karst Landscape?

500
Who encouraged crop rotation with the planting of peanuts and soybeans?
George Washington Carver

What are the three types of load in order from fast flowing stream to slow flowing stream? Give an example of each.
Bed load, suspended load, and dissolved load.
500
Why is it good and bad for farming on a flood plain?
Good = Fertile Soil Bad = Risk of flooding
500
How does a longshore current work and what does it do?
As waves approach a beach at an angle they push water along the beach and create a current that is parallel to the beach, called the longshore current. The longshore current carries sand away from a beach in erosion and leaves sand on other beaches in deposition.
