Slow Changes to the Earth

A pile of sand is found at the mouth of a river. Which is most likely the reason the sand is piled in this area?

• The river’s movement caused erosion and moved the sand downstream.

• A landslide occurred and the river moved sand far away from that area.

• An earthquake created sand and the river moved it downstream.

• The river caused weathering and moved the sand downstream.

How does erosion shape Earth′s surface differently than an earthquake?

• Erosion affects Earth’s surface less often than earthquakes do.

• Erosion makes changes over time and earthquakes make changes quickly.

• Erosion makes changes quickly and earthquakes make changes over time.

• Erosion affects Earth’s surface in a negative way while earthquakes affect it in a positive way.

Which best explains why sand can be seen piled up around plants on a beach?

• Ocean water is pushing the plants away.

• Ocean water is moving the sand to other beaches.

• Gravity is moving the sand to higher places on the beach.

• Wind is eroding the sand, moving it from one place to another.

Which would most likely cause an increase in erosion to a flat area with little vegetation?

• high humidity (amount of moisture in the air)

• increased rainfall
