Changes in the Geosphere

Front

What is the geosphere?

Back

The geosphere is the solid part of the Earth, including the crust and the upper mantle, which is composed of rocks and minerals.

Front

What are tectonic plates?

Back

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

Front

What is a transform boundary?

Back

A transform boundary is a type of tectonic plate boundary where two plates slide past each other, often causing earthquakes.

Front

What is the result of plate collision?

Back

When tectonic plates collide, they can create mountain ranges, earthquakes, and sometimes volcanic activity.

Front

Who proposed the Continental Drift Theory?

Back

Alfred Wegener proposed the Continental Drift Theory, suggesting that continents were once connected and have since drifted apart.

Front

What geological event is commonly associated with transform boundaries?

Back

Earthquakes are commonly associated with transform boundaries.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, tectonic plates move towards each other, which can lead to the formation of mountains or subduction zones.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new crust as magma rises to the surface.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another, often leading to volcanic activity and earthquakes.

Front

What are volcanoes?

Back

Volcanoes are openings in the Earth's crust where molten rock, ash, and gases can escape from below the surface.
