100

This is the term for mapping the ocean floor.

What is bathymetry? 

100

This type of plate boundary creates new lithosphere.

What is gravity pulling material closer to the center?

(Gravity and rotation)

200

This lies directly below the lithosphere.

What is the asthenosphere?

This island chain is a classic example of a hot spot.

What is Hawaii?

The dipole nature of Earth's magnetic field explains this.

Why compasses align with the magnetic north?

300

This evidence most directly supports the Big Band Theory.

What is cosmic background radiation (static on TV)?

300

This is what marks the crust mantle boundary.

What is the Moho?

300

This occurs when continental lithosphere stretches and thins.

What is a continental rift?

300

This force pulls a tectonic plate downward at a subduction zone.

Increases in temperature and pressure with depth.

500

This is why Alfred Wegener concept of continental drift was initally rejected.

What is he lacked the mechanism explaining continental movement?

500

Elements up to Fe are primarily produce during this.
