What is a Transform Boundary?

Back

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

Front

What is a Convergent Boundary?

Back

A Convergent Boundary is where two tectonic plates collide, leading to the formation of mountains, earthquakes, and volcanic activity.

Front

What is a Divergent Boundary?

Back

A Divergent Boundary is where two tectonic plates move apart from each other, allowing magma to rise and create new crust, often forming mid-ocean ridges.

Front

What causes tectonic plates to move?

Back

Tectonic plates move due to the convection currents in the mantle, where heated magma rises and spreads out, pushing the plates apart.

Front

What is produced at a Transform Boundary?

Back

Earthquakes are commonly produced at Transform Boundaries due to the friction and stress as plates slide past each other.

Front

What is the Asthenosphere?

Back

The Asthenosphere is a semi-fluid layer of the Earth's mantle located beneath the lithosphere, allowing tectonic plates to move.

Front

What is the difference between the Inner Core and Outer Core?

Back

The Inner Core is solid and composed mainly of iron and nickel, while the Outer Core is liquid and also made of iron and nickel.

Front

What are the effects of a Convergent Boundary?

Back

Convergent Boundaries can lead to earthquakes, volcanic eruptions, and the formation of mountain ranges.

Front

What is the role of magma in plate tectonics?

Back

Magma plays a crucial role in plate tectonics by rising to the surface, creating new crust at divergent boundaries and causing movement of tectonic plates.

Front

What is a Mid-Ocean Ridge?

Back

A Mid-Ocean Ridge is an underwater mountain range formed by the upwelling of magma at divergent boundaries.
