Term

If stream 1 was located on flat land and stream 2 was located on land that sloped, which stream would erode more soil?

 

Definition

Stream 2 because the higher the slope is, the faster the water will flow, which will cause more erosion.

Term

Would location would work best to build a house?

 

A. A steep slope with loosely packed soil, and very few plants or trees.

 

B. A steep slope with tightly packed soil, and many plants and trees.

Definition

Location B would work best because the soil is tightly packed, so there would be less erosion. Also, the plants and trees would hold the soil in place to help decrease the amount of erosion.

 

Term

How does runoff from rain affect the land?

 

Definition

Runoff affects the land by causing erosion to the land, gullies may be formed, and the rain will darken in color.

Term

How does stream water become precipitation?

 

Definition

In the water cycle, the sun evaporates water, which then turns to water vapor. As the water vapor cools in the atmosphere and turns back into a liquid it condenses into a cloud through a process called condensation. Then, water returns to earth through precipitation.

Term

How could a rain storm affect the shape of the land?

 

Definition

The heavier the precipitation, the greater the amount of runoff. The greater the amount of runoff, the greater the amount of erosion that will occur. Erosion shapes the land.

Which direction did the water flow? How do you know?

 

Definition

The water flowed from right to left because the heavier and larger particles were deposited first. The smaller particles traveled further and were deposited somewhere else.
