Who proposed the theory of continental drift?

Back

Alfred Wegener proposed the theory that all continents were once joined together in a single landmass.

Front

What are convergent plate boundaries?

Back

Convergent plate boundaries are areas where two tectonic plates move toward each other, often causing earthquakes and volcanic activity.

Back

Earthquakes are caused by vibrations in the earth resulting from the sudden movement of rocks along faults.

Front

What is a tsunami?

A tsunami is a series of ocean waves generated by underwater earthquakes or volcanic eruptions.

Front

What is seismology?

Back

Seismology is the scientific study of earthquakes and the propagation of seismic waves through the Earth.

Front

What is the epicenter of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above the location where an earthquake originates.

Front

What is a fault in geological terms?

Front

What is the difference between a tidal wave and a tsunami?

Back

A tidal wave is caused by the gravitational pull of the moon and sun, while a tsunami is caused by underwater seismic activity.

Front

What is the Richter scale?

Back

The Richter scale is a logarithmic scale used to measure the magnitude of earthquakes.
