Plate Tectonics Flashcard

Front

What causes the movement of tectonic plates?

Back

The movement of tectonic plates is caused by convection currents in the Earth's mantle.

Front

What percentage of all earthquakes occur around the Ring of Fire?

Back

90% of all earthquakes occur around the Ring of Fire.

Front

What happens when two tectonic plates are spreading apart?

Back

New ocean crust is created.

Front

What is one piece of evidence for Continental Drift?

Back

Fossils of the same plant have been found on several continents.

Front

Which of the following is NOT evidence of continental drift?

Back

Plates do not match up or have similar rock.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other.

Front

What is the theory of Plate Tectonics?

Back

The theory of Plate Tectonics explains how the Earth's plates move and interact, causing geological events like earthquakes and volcanic eruptions.

Front

What is the Ring of Fire?

Back

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

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another plate and sinks into the mantle.

Front

What is continental drift?

Back

Continental drift is the theory that continents have moved over geological time and were once joined together.
