Plate Tectonics 2.0

Front

What is a transform boundary?

Back

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

Front

What geologic feature is commonly associated with transform boundaries?

Back

Earthquakes are commonly associated with transform boundaries.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, tectonic plates pull apart from each other.

Front

What geologic feature is formed at mid-ocean ridges?

Back

Mid-ocean ridges are formed at divergent boundaries where tectonic plates are moving apart, leading to the creation of new oceanic crust.

Front

What drives tectonic plate movement?

Back

Convection currents in the mantle are thought to be the driving force behind tectonic plate movement.

Front

Where do convection currents cause tectonic plates to diverge?

Back

Convection currents cause tectonic plates to diverge at mid-ocean ridges.

Front

How do scientists estimate the thickness of Earth's layers?

Back

Scientists estimate the thickness of Earth's layers by studying seismic waves.

Front

What is the composition of the Earth's core?

Back

The Earth's core is mostly made up of Nickel and Iron.

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate moves under another plate and sinks into the mantle.

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.
