What is the Pacific Ring of Fire?

Back

A region in the Pacific Ocean basin characterized by high tectonic activity, including earthquakes and volcanic eruptions.

Front

What evidence supports the theory of plate tectonics?

Back

Fossils found on different continents, locations of volcanoes and earthquakes, and similarity in the coastlines of continents.

Front

What is erosion?

Back

The process by which water, ice, wind, or gravity picks up and moves weathered rock and soil from one place to another.

Front

What is weathering?

Back

The natural chemical or physical processes that break down rock on Earth's surface.

Front

What type of boundary is associated with the formation of new crust?

Back

Divergent boundaries.

Front

What are tectonic plates?

Back

Massive slabs of Earth's lithosphere that fit together like a jigsaw puzzle and move over the semi-fluid asthenosphere.

Front

What is subduction?

Back

The process by which one tectonic plate moves under another plate and sinks into the mantle.

Front

What is a convergent boundary?

Back

A tectonic boundary where two plates collide, often forming mountains or causing earthquakes.

Front

What is a divergent boundary?

Back

A tectonic boundary where two plates move apart, leading to the formation of new crust, such as mid-ocean ridges.

Front

What is a transform boundary?

Back

A tectonic boundary where two plates slide past each other, causing earthquakes.
