8.9AB Plate Tectonics & Boundaries

Front

What is a convergent boundary?

Back

A convergent boundary is a location where two tectonic plates collide, often resulting in the formation of mountains, earthquakes, or volcanic activity.

Front

What geological feature is created when an ocean plate collides with another ocean plate?

Back

A volcanic arc of islands is created when an ocean plate collides with another ocean plate.

Front

What is the evidence for Continental Drift that suggests continents fit together like puzzle pieces?

Back

The continent shape provides evidence for Continental Drift, indicating that continents were once joined together.

Front

What type of boundary is associated with earthquakes?

Back

Transform boundaries are associated with earthquakes.

Front

True or False: Continental plates move quickly enough for us to feel them.

Back

False. Continental plates move very slowly, typically at rates of a few centimeters per year.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often resulting in sea-floor spreading and the formation of mid-ocean ridges.

Front

What is sea-floor spreading?

Back

Sea-floor spreading is the process by which new oceanic crust is formed at mid-ocean ridges as tectonic plates pull apart.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with one another, causing geological activity.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, leading to earthquakes.

Front

What is the Ring of Fire?

Back

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