Plate Boundaries & Hotspots

Front

What is a hot spot in geology?

Back

A hot spot is a location on the Earth's surface that has experienced active volcanism for a long period of time, typically due to a plume of hot material rising from the mantle.

Front

How do volcanoes form at hot spots?

Back

Volcanoes form at hot spots when magma from the mantle rises through the crust, creating volcanic islands or mountains.

Front

What is a tsunami?

Back

A tsunami is a large and powerful ocean wave caused by underwater earthquakes, volcanic eruptions, or landslides.

Front

What geological forces are responsible for mountain ranges?

Back

Mountain ranges are typically formed by converging tectonic plates that push against each other.

Front

What type of plate boundary is characterized by plates pushing together?

Back

A convergent boundary.

Front

What happens at a mid-ocean ridge?

Back

At a mid-ocean ridge, molten material rises from the mantle, creating new oceanic crust as tectonic plates pull apart.

Front

What is sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is formed at mid-ocean ridges as tectonic plates move apart.

Front

What is the significance of the 2004 Indian Ocean tsunami?

Back

The 2004 Indian Ocean tsunami was significant as it was caused by a major undersea earthquake at a convergent plate boundary, resulting in widespread devastation.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries, causing geological activity.

Front

What is the difference between convergent and divergent boundaries?

Back

Convergent boundaries occur where plates push together, while divergent boundaries occur where plates pull apart.
