Intro Earthquakes/Volcanoes + Continental Drift (L1 + 2.1)

Front

What does the Theory of Continental Drift propose?

Back

The Theory of Continental Drift proposes that the continents were once part of a single supercontinent called Pangaea, which broke apart and drifted to their current locations.

Front

What geological evidence supports the Theory of Continental Drift?

Back

Geological evidence includes the presence of similar rock formations and fossils on different continents, as well as glacial scratches found in warm climates.

Front

What is the name of the ancient supercontinent that existed around 28 million years ago?

Back

Pangaea.

Front

What is an extinct volcano?

Back

An extinct volcano is one that is not likely to erupt again in the future.

Front

What is a dormant volcano?

Back

A dormant volcano is one that has not erupted in a while but is likely to erupt again.

Front

What type of evidence do glaciers leave behind that supports continental drift?

Back

Glaciers leave behind deep grooves or scratches in rocks, which indicate past glacial activity in areas that are now warm.

Front

What is the significance of the alignment of mountain ranges across continents?

Back

The alignment of mountain ranges across continents suggests that these landmasses were once connected, supporting the Theory of Continental Drift.

Front

How do tectonic plates relate to earthquakes and volcanoes?

Back

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

Front

What is the difference between a volcano and a mountain?

Back

A volcano is a geological structure that can erupt lava, ash, and gases, while a mountain is a large landform that rises prominently above its surroundings, which may or may not be volcanic.

Front

What are the three main types of volcanoes?

Back

The three main types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), and cinder cone volcanoes.
