Plate Tectonics Test

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate is being forced underneath another plate, often leading to volcanic activity and earthquakes.

Front

What is the oldest section of seafloor at a mid-ocean ridge?

Back

The oldest section of seafloor at a mid-ocean ridge is the part that is farthest from the ridge itself, as new crust is formed at the ridge and older crust moves away.

Front

What was Pangea?

Back

Pangea was a supercontinent that existed millions of years ago, where all the continents were joined together.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates are crashing together, often resulting in mountain formation or subduction.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates are moving apart, leading to the formation of new crust, such as at mid-ocean ridges.

Front

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past one another horizontally, often causing earthquakes.

Front

What geological features are commonly associated with subduction zones?

Back

Subduction zones are commonly associated with deep ocean trenches, volcanic arcs, and earthquakes.

Front

How do tectonic plates move?

Back

Tectonic plates move due to convection currents in the Earth's mantle, driven by heat from the Earth's core.

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, primarily due to tectonic plate boundaries.

Front

What is the process of sea-floor spreading?

Back

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