Plate tectonics

Front

What type of boundary is formed at a Mid Ocean Ridge?

Back

Divergent Boundary

Front

Describe the process that occurs at a divergent boundary.

Back

Two tectonic plates move away from each other, allowing magma to rise and create new crust, forming new lithosphere.

Front

What theory explains that continents were once joined together and have drifted apart over time?

Back

Continental Drift

Front

What causes the movement of tectonic plates?

Back

Convection currents in the Asthenosphere.

Front

What does the Plate Tectonic Theory state about Earth's outer layer?

Back

Earth's outer layer is broken into large, slowly moving pieces.

Front

What is the primary feature of a convergent boundary?

Back

Two tectonic plates move towards each other, often resulting in subduction or mountain formation.

Front

What geological features are commonly associated with divergent boundaries?

Back

Mid-ocean ridges and rift valleys.

Front

What is subduction, and where does it occur?

Back

Subduction is the process where one tectonic plate moves under another, occurring at convergent boundaries.

Front

What is the significance of the Asthenosphere in plate tectonics?

Back

The Asthenosphere is a semi-fluid layer that allows tectonic plates to move due to convection currents.

Front

What are transform boundaries, and what do they cause?

Back

Transform boundaries occur where two plates slide past each other, causing earthquakes.
