What is a Transform Boundary?

Back

A Transform Boundary is a tectonic plate boundary where two plates slide past each other horizontally. This movement can cause earthquakes when the plates get stuck and then slip.

Front

What force in the mantle is responsible for the movement of tectonic plates?

Back

Convection currents are the force in the mantle that drives the movement of tectonic plates.

Front

What is the Mantle?

Back

The Mantle is the layer of the Earth located between the crust and the core, composed of semi-solid rock that flows slowly.

Front

What is erosion?

Back

Erosion is the process of removing and transporting surface material by wind, water, or ice.

Front

Which two spheres does a dolphin need to survive?

Back

A dolphin needs the Hydrosphere (ocean) and the Atmosphere (air) to survive.

Front

What is a Convergent Boundary?

Back

A Convergent Boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath another, leading to subduction.

Front

What is a Divergent Boundary?

Back

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

Front

What are convection currents?

Back

Convection currents are the circular movements of fluid caused by the heating and cooling of material, which drive the movement of tectonic plates.

Front

What is the Geosphere?

Back

The Geosphere refers to the solid parts of the Earth, including the crust, mantle, and core.

Front

What is the Hydrosphere?

Back

The Hydrosphere encompasses all the water on Earth, including oceans, rivers, lakes, and water vapor.
