1) Follow the directions. Use colored pens or pencils on the map when you need to draw.

• Circle the area of highest elevation in the United States in red.• Circle the area of low elevation around the Hudson Bay in green.• Circle the name of the ocean west of the United States in blue.• Circle the Appalachian Mountains in the eastern United States in brown.

2) Explain how data from the map supports this claim from the Student Text: “About 80 percent of earthquakes happen around the Pacific Ocean.”

3) Identify two other patterns about earthquakes.

1) Follow the directions. Used colored pens or pencils on the map when you need to draw. • Trace the pattern of earthquakes around the Pacific Ocean in red.• Trace the pattern of earthquakes along southern Europe in blue.

3) Identify two other patterns about volcanoes.

4) Think about the other maps you have seen in this lesson. What pattern do you see in the location of earthquakes and volcanoes? Why do you think this is?

1) Use a red pen or pencil to trace the pattern of volcanoes that creates the Ring of Fire around the Pacific Ocean.

4) Think about the other maps you have seen in this lesson. What pattern do you see in the location of earthquakes, volcanoes, and mountains?

1) Use a red pen or pencil to circle at least three mountain ranges located along the Ring of Fire.

2) What pattern do you notice between the boundaries of Earth’s plates and the locations of Earth’s mountains, volcanoes, and earthquakes?

1) Use your map of mountains, volcanoes, and earthquakes to describe the main pattern you noticed for each feature.

Earth’s Volcanoes and Earthquakes

Examine the map to look for similarities and differences of where earthquakes and volcanoes are found on Earth. Then complete the Venn diagram below.

• In the left circle, write down at least one pattern only volcanoes have. • In the right circle, write down at least one pattern only earthquakes have. • Where the two circles overlap, write down at least two patterns that volcanoes and

earthquakes share.
