The Earth's Crust

Front

What are Mid-Ocean Ridges?

Back

Mid-Ocean Ridges are underwater mountain ranges formed by tectonic plates moving apart.

Front

Where do Volcanoes and Earthquakes commonly occur?

Back

Volcanoes and Earthquakes commonly occur at the borders/boundaries of tectonic plates.

Front

What is the difference between Oceanic Crust and Continental Crust?

Back

Continental Crust is thicker than Oceanic Crust.

Front

What is a tectonic plate?

Back

A tectonic plate is a large section of the Earth's crust that moves and interacts with other plates.

Front

What happens at the boundaries of tectonic plates?

Back

At the boundaries of tectonic plates, they can collide, pull apart, or slide past each other, causing geological activity.

Front

What is a trench in geological terms?

Back

A trench is a deep, narrow depression in the ocean floor, often formed by the subduction of one tectonic plate beneath another.

Front

How fast do tectonic plates move?

Back

Tectonic plates move a few centimeters per year.

Front

What is a volcano?

Back

A volcano is an opening in the Earth's crust through which lava, ash, rock, and gases erupt.

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, consisting of solid rock.

Front

What is the significance of the mid-ocean ridge?

Back

The mid-ocean ridge is significant because it is where new oceanic crust is formed as tectonic plates pull apart.
