Earth's Features

A student developed a model to show the progression of a sea arch and the ocean waves using playdoh. Dates labeled below the image show a timelapse. Four of the student’s classmates analyzed the student model on how the model shows constructive and destructive forces. Which of the following students made a correct conclusion based upon the

• Student A: A sea arch is formed by a destructive force. Evidence from the model is that waves carved

  out the land in a long period of time.

• Student B: A sea arch is formed by a constructive force. Evidence from the model is that waves build

  up land in another area in a long period of time.

• Student C: A sea arch is formed by a destructive force. Evidence from the model is that an earthquake

  caused the arch to fall down in a short period of time.

• Student D: A sea arch is formed by a constructive force. Evidence from the model exhibits deposition

  when the waves build up the land in a short period of time.

A group of students were observing the land around the creek near their school. Each student was asked to explain the natural processes that had shaped the creek and the land around it. Which is the best argument to explain what happened?

• It was a fast constructive process caused by the wind.

• It was a slow destructive process caused by the movement of water.

• It was a slow constructive process caused by earthquakes.

Which example describes a method that could be used to prevent erosion on a hill?

• Make the hill steeper.

• Plant trees or plants along the hill.

• Put stones at the bottom of the hill.

The photograph below shows the destruction caused by fast flowing currents in a river near a small town. Based on what you can observe in the photograph, what type of technology should the town consider to limit the impacts of future flooding?

• The town should consider constructing a levee to reduce erosion.

• The town should consider contour plowing to reduce the loss of rich soil.

• The town should consider terracing to reduce runoff.

• The town should consider constructing a dam to reduce erosion.
