Plate Tectonics Review

Front

What is a Transform Boundary?

Back

A Transform Boundary is a type of plate boundary where two tectonic plates slide past each other horizontally. This movement can cause earthquakes.

Front

Where is the oldest rock typically found at a divergent boundary?

Back

The oldest rock is usually found farthest from the mid-ocean ridge, where new magma rises and cools to form new rock.

Front

What happens at a Divergent Boundary?

Back

At a Divergent Boundary, tectonic plates pull apart from each other, leading to the formation of new crust as magma rises to the surface.

Front

What causes Earth's tectonic plates to move?

Back

Earth's tectonic plates move due to convection currents in the mantle, which are caused by the heat from the Earth's core.

Front

What is a Convergent Boundary?

Back

A Convergent Boundary is a type of plate boundary where two tectonic plates come together, often leading to one plate being forced beneath another, a process known as subduction.

Front

What is a Divergent Boundary?

Back

A Divergent Boundary is a plate boundary where two tectonic plates move away from each other, often resulting in volcanic activity and the formation of new oceanic crust.

Front

What is the role of convection currents in plate tectonics?

Back

Convection currents in the mantle transfer heat from the Earth's core to the surface, driving the movement of tectonic plates.

Front

What geological features are commonly associated with Convergent Boundaries?

Back

Convergent Boundaries are often associated with mountain ranges, deep ocean trenches, and volcanic arcs.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another and sinks into the mantle, often leading to volcanic activity.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.
