The triangular-shaped deposit at the mouth of a river is called...

• an island

• an earthquake

• deposition

• a delta

The illustration below shows a meandering river moving toward the ocean. What most likely happens to the river in the area indicated by the arrow?

• The river is narrowed by mechanical weathering caused by increased rain water.

• The river slows down as it nears the ocean and deposits silt and sediment.

• The river will eventually completely fill in with soil.

• The river is widened by deposition.

The illustration below represents the Grand Canyon.

• The layers of rock were broken apart by physical weathering caused by tree roots then blown away by the wind.

• The layers of rock were eroded by the strong winds whipping through the canyon.

• The layers of rock were eroded by chemical weathering caused by acid rain.

• The layers of rock were eroded by the force of the Colorado River.

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
