Layers of the Earth
This is the densest layer of the earth
What is the inner core
This theory states that the youngest rocks of ocean floors are at divergent boundaries, moving outward.
What is seafloor spreading
This is the theory that all continents are fragments of Pangaea now drifting apart
What is the Continental Drift Theory
Earthquakes, Volcanoes, ocean ridges, and ocean trenches are usually located in relation to these
What is a plate boundary

This is a seafloor landmark where new seafloor is being destroyed.
What is deep-sea trench.
What is the name of the supercontinent before the continents are what they are now?
What is Pangea.
This is the mechanism which causes the plates to move.
What is convection cycles in the mantle.
This deadly force of nature is often created by earthquakes.

What is less dense under the ocean and more dense under the continents.
This is three main pieces of evidence supporting the theory of continental drift.
What is continents fitting together like a puzzle, fossils matched on each continent, evidence of glaciers where they should never have been, and landforms such as mountains and rivers matched on continents.
Plate subduction often creates these two landmarks.

what is the asthenosphere
This is the device/technology people used to map the seafloor.
What is sonar.
Continental Drift Theory was not accepted because it did not explain this
