Earth Science Study Guide

Which of the following best compares the power of wind and earthquakes to change the Earth's surface features?

• Wind power is only constructive because it moves large particles faster than small particles to build up dunes. Earthquake power only destructive and is common on fault lines and is very damaging.

• Wind power is both constructive and destructive because builds up dune shape or cause erosion over time. Earthquake power is both constructive and destructive because it very quickly builds up new land formations or causes rifts and landslides.

• Wind power is only destructive as high wind speeds during storms are very damaging. Earthquake power is only constructive because it causes new land formations when two tectonic plates collide.

• Wind power is only constructive because it builds up sand dunes and moves them over time. Earthquake power is only destructive as it causes rifts and landslides.

Why are levees built next to a river?

• to collect water for drinking

• to force water underground for crops

• to keep animals from drinking the water

• to protect people from rising water during a large storm

A student goes on a hike on a trail at a state park. She notices a plant growing out of the cracks of a rock. A year later, the student returns to the park and hikes on the same trail. She notices that the plant has now grown into a small tree and the rocks have been broken apart. Based on the passage, which action caused the rocks to break apart?

• biological weathering

• mechanical weathering

• erosion by the action of wind

• erosion by the action of water

What would help to reduce soil erosion?

• the loosening of soil

• a period of heavy rainfall

• an increase in the slope of the land

• the planting of more vegetation

Which force of erosion would most likely cause large amounts of loose soil to move down the slope of a hill?

• heat

• wind

• water

• chemicals

What problem are the beach grasses that have been planted along the beaches most likely intended to solve?

• How can the pollution of the seas be prevented?

• How can the erosion of shorelines be reduced?

• How can the diversity of marine life be improved?

• How can the level of rising sea water be decreased?

Which of the following correctly describes a dam?

• They are built at the top of waterfalls and they keep water from leaving the plateau.

• They are built beside rivers and they control the spread of flood water.

• The are built besides lakes and they prevent the water from evaporating.

• They are built across waterways and they block, or change the natural flow of the water.

What can change a river and its direction of flow over time?

• Erosion and deposition of a river's material can change the path of a river.

• The flow if a river never changes.

• It changes when the water evaporates from the river.

• There must be acid rain for the flow of a river to change.
