Runoff and Erosion

Students were making a model to demonstrate the effects of runoff.  Which of the following should they include in the model to show the least amount of runoff and to decrease erosion?

• build a shopping center because it will decrease the amount of runoff

• build a shopping center because it will increase the amount of runoff

• increase the amount of vegetation because it will decrease the amount of runoff

• decrease the amount of vegetation because it will increase the amount of runoff

Students are making a model of river erosion using a stream table. What can the students do to increase the amount of erosion in their model?

• Increase the amount and speed of the water.

• Decrease the amount and speed of the water.

• Increase the amount of rocks in their model.

• Decrease the temperature of the water.

Which statement best explains what is happening at point X(outside bend) in the picture?

• Weathered rocks and sand are getting picked up and carried downstream because the water moves faster here.

• Weathered rocks and sand are getting picked up and carried downstream because the water moves slower here.

• Rocks and sand are being deposited by the river from farther upstream.

• Wind is moving large rocks and sand from one side of the river to the other.

Which agent of erosion would most likely form a U shaped mountain valley like the one in the image?

• erosion by gravity

• erosion by water

• erosion by glaciers

• erosion by wind

Howard's local beach has been hit by several strong storms over the last year. If Howard were to compare a photograph of the beach from last year with a photograph of the beach today, what would he most likely observe?

• The storms compacted the sand on the beach, cementing it into sedimentary rock.

• The storms created large waves that flooded the beach creating sand dunes.

• The storms weathered boulders on the beach, breaking them down and making the beach larger.

• The storms eroded the sand on the beach, carrying it away and making the beach smaller.

Which list correctly identifies the agents of erosion?

• gravity, glaciers, water and wind

• water, wind, carbonic acid and gravity

• water, gravity, wind and ice wedging

• Glaciers, abrasion, gravity, humans and oxygen

Deforestation is the removal of trees in a forest to make space for homes and farmland and to obtain wood for fuel, manufacturing and construction. How does this human activity change the surface of Earth?

• The removal of tress and vegetation leads to a decrease in soil erosion by wind or water.

• The removal of tress and vegetation leads to an increase in soil erosion by wind or water.

• The removal of tress will lead to more oxygen production in the atmosphere.

• The removal of trees and vegetation will lead to an increase in soil erosion by acids and ice wedging.

Students in Earth Science class are making a model to represent wave erosion as seen in the image. What can the students expect to observe after creating ocean waves in their model?

• The rocks and sediment on the land will be eroded and deposited on the ocean floor which will increase the size of the hill/cliff and create a delta.

• The rocks and sediment on the land will be eroded and deposited on the ocean floor which will decrease the size of the hill/cliff and create a delta.

• The rocks and sediment on the land will be eroded and deposited on the ocean floor which will decrease the size of the hill/cliff and create a beach.

• The rocks and sediment on the land will be eroded and deposited on the ocean floor which will increase the size of the hill/cliff and create a beach.
