Earthquakes and Boundaries

Scientists use ___ to study energy from earthquakes

• Maps

• Radio waves

• Seismic waves

• Electromagnetic waves

Give two relationships between seismic activity and tectonic activities

• If you have an active boundary, you have stronger earthquakes

• If you have a quiet boundary, you have stronger earthquakes

• Most strong earthquakes oocur at divergent boundaries

• Most strong earthquakes occur at transform and convergent boundaries.

San Andreas is one of the most active ___ boundaries

• Convergent

• Divergent

• Transform

• Compressional

Two events that can occur at plate boundaries are:

• Electromagnetic changes

• Volcanoes

• Earthquakes

• Mudslides

When the magma moves up through the lithosphere and then the plate moves away demonstrates ______

• Hot spot

• Convection currents

• Earthquake zones

• Ring of Fire

The Hawaiian Islands are an example of
