6.2 & 6.3 (Test Practice)

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another and sinks into the mantle, often forming deep ocean trenches.

Front

What is a fault in geology?

Back

A fault is a break in a rock along which movement has occurred, leading to earthquakes and other geological activity.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Front

What are transform plate boundaries?

Back

Transform plate boundaries are locations where two tectonic plates slide past each other, often causing earthquakes.

Front

What is the difference between convection and conduction?

Back

Convection is the transfer of heat through fluid movement, while conduction is the transfer of heat through direct contact between materials.

Front

What is the asthenosphere?

Back

The asthenosphere is a semi-fluid layer of the upper mantle that allows tectonic plates to move.

Front

What are deep ocean trenches?

Back

Deep ocean trenches are the deepest parts of the ocean, formed by the subduction of one tectonic plate beneath another.

Front

What is continental drift?

Back

Continental drift is the theory that continents move over geological time, changing their positions relative to each other.

Front

What causes earthquakes at transform boundaries?

Back

Earthquakes at transform boundaries are caused by the friction and stress that build up as tectonic plates slide past each other.

Front

What is the role of the mantle in plate tectonics?

Back

The mantle plays a crucial role in plate tectonics by providing the heat and convection currents that drive the movement of tectonic plates.
