Malik and Jeanine were asked to demonstrate the answer to the question, “How does the slope of a mountain effect the amount of erosion that occurs?” They set up their demonstration, as shown in the illustration below, then measured and recorded the amount of soil eroded down the slopes by the water. The data table shows the average of their results. Which statement best explains how the slope of a mountain affects the amount of erosion?

• The height of a slope has no impact on the amount of erosion which occurs

• A higher slope results in more erosion.

• A lower slope results in more erosion

• A higher slope results in less erosion

The earth is built up and torn down in many ways. Physical and chemical weathering are processes which are very important in making soil. Which statement accurately describes an example of chemical weathering?

• In order for rock to become metamorphic rock, it must be heated and extreme pressure applied.

• In Alaska, rocks are broken due to continuous freezing and thawing of water sitting in cracks.

• Beautiful and strange rocks, shaped by blowing sand, dot the Western United States landscape.

• Sinkholes are formed in central Florida as seeping water dissolves underground limestone rocks

What is mechanical weathering?

• Process through which rocks are physically broken into smaller pieces.

• Rocks are broken down through chemical changes.

• Rocks are worn away from acid in plant roots.
