3.2 Study Guide

During the 1960s, geologists used seismometers to record information that suggested Earth's plates were in motion. The data recovered by the seismometers showed that earthquakes, volcanoes, and other geologic features tend to occur or be present

• around the centers of tectonic plates.

• on the edges of tectonic plates.

• in Earth's outer core.

• 
  in Earth's inner core.

Why do many earthquakes and volcanoes occur along the Ring of Fire?

• The Ring of Fire increases convection in Earth's core.

• The Richter scale is less active around the Ring of Fire.

• The Ring of Fire is located along active plate boundaries.

• 
  The Atlantic Ocean is surrounded by the Ring of Fire.

• the continents will remain where they are now.
• the Pacific Ocean will shrink.

Most of Earth's volcanoes are formed by

• 
  the interaction of continental plates.

• the melting of ice on continental plates.

• meteorites that strike continental plates.

•
