Unit 4 Test Review: Plates, Volcanoes and Earthquakes

Front

What are the slowest seismic waves?

Back

Surface waves are the slowest seismic waves.

Front

Which scale rates earthquakes based on the amount of damage done?

Back

The Mercalli Scale rates earthquakes based on the amount of damage done.

Front

Which seismic wave travels the fastest?

Back

The Primary Wave travels the fastest.

Front

What natural hazard can a huge undersea earthquake off the Alaskan coastline produce?

Back

A huge undersea earthquake can produce a Tsunami.

Front

What kind of plate boundary is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other.

Front

What are P waves?

Back

P waves, or Primary waves, are the fastest seismic waves and can travel through solids and liquids.

Front

What are S waves?

Back

S waves, or Secondary waves, are seismic waves that can only travel through solids and are slower than P waves.

Front

What is a tsunami?

Back

A tsunami is a series of ocean waves caused by large underwater disturbances, such as earthquakes.

Front

What is the difference between a Richter Scale and a Mercalli Scale?

Back

The Richter Scale measures the magnitude of an earthquake, while the Mercalli Scale measures the intensity and damage caused.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally.
