Plate Tectonics

Scientists think the continents once formed a large, single landmass that broke apart, and the continents slowly drifted to their present locations. What is the name given to this claim?

• continental slope

• continental shelf

• continental drift

• continental rise

The asthenosphere is the part of the mantle on which the tectonic plates move. Which of these statements best describes a characteristic of the asthenosphere that allows the tectonic plates to move?

• It is porous.

• It is permeable.

• It is rigid.

• It is soft.

A plate boundary is a place where two tectonic plates meet. There are several types of tectonic plate boundaries. Which statement below shows the correct definition of a tectonic plate boundary?

• At a divergent boundary, one plate sinks under another plate.

• At a convergent boundary, plates slide past each other.

• At a transform boundary, plates move apart.

• At a divergent boundary, plates separate.

Convection currents in the mantle contribute to tectonic plate movement. What is a convection current?

• the transfer of energy by direct contact

• the transfer of energy by the movement of matter

• the transfer of energy through a solid, such as the Earth’s crust

• the transfer of energy from a region of lower temperature to a region of higher temperature
