Shore

The level of the ocean rises and falls several times during the day due to the pull of gravity by the moon. What are these changes in level of the water along the shore called?

• Waves

• Currents

• Tides

• Tsunami

A severe storm would be most likely to damage a coastal area by causing

• erosion

• deposition

• pollution

• estuary

_______ can either form a beach by depositing sand or destroy a beach by eroding the sand. 

• waves

• currents

• storms

• all of these

While most land areas are slow to change, the shape of beaches changes daily. Which of the following best explains this? 

• The heating and cooling of beaches changes the shape.

• Coastal animals change the shape of the shoreline.

• The wave action adds and removes sand daily.

• Sea level decreases each day, creating more coastal land.

What is likely to cause the most erosion along a beach in a short period of time?

• tides

• storm waves

• longshore current

• formation of a sandbar

Where is an estuary most likely to form?

• In a salt marsh

• Between two barrier islands

• Where two inlets meet

• Where a river flows into an ocean

The earth is in a constant state of motion which creates forces that change the face of the Earth. Weathering is the force that breaks down rocks and other objects in nature into smaller pieces and erosion is the movement of the pieces that were broken off through the weathering process.

Choose the forces that cause weathering and erosion along a coastline.

• ice, waves, tides

• waves, tides, longshore currents

• tides, longshore currents, animals

How do tides affect the ocean shore zone?

• Tides bring in sand and shells that are deposited as the tide goes out.

• Tides provide plants with water to live.

• Tides protect the coastline from strong storms.

• Tides keep the air temperature cool.
