Plate Tectonics

Front

What are the layers of the Earth in order from the surface to the center?

Back

Crust, mantle, outer core, inner core.

Front

What geological process occurs at mid-ocean ridges?

Back

Sea-floor spreading, where molten material rises from the mantle and erupts.

Front

What is the term for the process where the ocean floor sinks beneath a deep-ocean trench?

Back

Subduction.

Front

How does new crust form without increasing the Earth's surface area?

Back

Crust is destroyed at the same time it is created.

Front

What is a transform boundary?

Back

A place where two tectonic plates slip past each other, moving in opposite directions.

Front

What is the primary driving force behind plate tectonics?

Back

Convection currents in the mantle.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is denser and thinner than continental crust.

Front

What is a convergent boundary?

Back

A boundary where two tectonic plates move toward each other, often causing subduction.

Front

What geological features are commonly formed at divergent boundaries?

Back

Mid-ocean ridges and rift valleys.

Front

What is the significance of the Ring of Fire?

Back

It is an area in the Pacific Ocean basin known for its high volcanic and seismic activity.
