Continental Drift and Plate Tectonics Review

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often resulting in one plate being forced beneath the other, leading to subduction.

Front

How do the Hawaiian islands form?

Back

The Hawaiian islands formed at a hotspot, which is a location where magma from the mantle rises to create volcanic islands.

Front

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other horizontally, causing earthquakes.

Front

True or False: Hotspots move in the mantle.

Back

False. Hotspots remain stationary while tectonic plates move over them.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, tectonic plates collide, which can cause mountain building, earthquakes, and 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.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another and sinks into the mantle.

Front

What geological features are commonly formed at divergent boundaries?

Back

Geological features such as mid-ocean ridges and rift valleys are commonly formed at divergent boundaries.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic plate movements.
