Back

Volcanoes can form at divergent, convergent, and transform boundaries.

Front

What happens to tsunami waves as they approach the shore?

Back

Tsunami waves lose speed but gain energy and height as they approach the shore.

Front

Where are most volcanoes located?

Back

The focus is located beneath the epicenter of an earthquake.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.

Front

What is the difference between the epicenter and the focus of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above the focus, which is the point where the earthquake originates.

Front

What are divergent boundaries?

Back

Divergent boundaries are tectonic plate boundaries where two plates move away from each other, often resulting in volcanic activity.

Front

What are convergent boundaries?

Back

Convergent boundaries are tectonic plate boundaries where two plates collide, which can lead to the formation of mountains, earthquakes, and volcanic activity.

Front

What is a tsunami?

Back

A tsunami is a series of ocean waves caused by any large and sudden displacement of water, often due to underwater earthquakes or volcanic eruptions.
