Unit 6A: Earth Interior

Front

What type of waves are surface waves?

Back

L waves (Love waves) are surface waves that travel along the Earth's surface.

Front

Identify the boundary between oceanic plates.

Back

Ocean-ocean boundary is where two oceanic plates meet, often leading to the formation of underwater features like trenches.

Front

What is isostacy?

Back

Isostacy is the equilibrium between the lithosphere and the asthenosphere, where the Earth's crust floats on the semi-fluid mantle.

Front

What is usually not found at plate boundaries?

Back

Passive environments are usually not found at plate boundaries, as they are characterized by minimal tectonic activity.

Front

Which physiographic province provides most of the state's coal?

Back

The Appalachian Plateau is known for providing most of the state's coal.

Front

What are P waves?

Back

P waves (Primary waves) are compressional waves that travel through solids and liquids and are the fastest seismic waves.

Front

What are S waves?

Back

S waves (Secondary waves) are shear waves that only travel through solids and are slower than P waves.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new crust.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to subduction or mountain building.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle beneath the lithosphere, allowing for tectonic plate movement.
