Plate Boundaries Practice

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate sinks below another, typically occurring at convergent plate boundaries.

Front

What is a tsunami?

Back

A tsunami is a giant wave caused by underwater earthquakes or volcanic eruptions.

Front

What geological feature is commonly found at a convergent boundary between two continental plates?

Back

Mountains are commonly formed at convergent boundaries between two pieces of continental crust.

Front

What technology was used during WWII to detect submarines and map the seafloor?

Back

Sonar was the technology used to detect enemy submarines and produce the first map of the seafloor.

Front

What occurs at a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics, where new oceanic crust is created.

Front

What is sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and gradually moves away from the ridge.

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.

Front

What is the focus of an earthquake?

Back

The focus of an earthquake is the point within the Earth where the earthquake originates.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, often associated with volcanic activity.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is denser and thinner than continental crust, which is thicker and less dense.
