Front

What is subduction?

Back

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

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, leading to subduction or mountain formation.

Front

What are the Himalayas?

Back

A mountain range in Asia formed by the collision of the Indian and Eurasian tectonic plates.

Front

What are the Andes Mountains?

Back

A mountain range in South America formed by the subduction of the Nazca Plate beneath the South American Plate.

Front

What is the significance of plate tectonics?

Back

Plate tectonics explains the movement of the Earth's plates and the geological activity associated with these movements.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is denser and thinner, while continental crust is thicker and less dense.

Front

What is the role of density in subduction?

Back

The denser oceanic crust subducts beneath the less dense continental crust.

Front

What is a fossil?

Back

The preserved remains or traces of ancient organisms, often found in sedimentary rock.
