Plate Tectonics

The crust is split into these two types of crust.

The types of heat transfer are Radiation, Convection, and _________________.

The rock that is the oldest along the ocean ridge is located  ___ away from the molten material

Subduction can cause this land feature to form along the continental crust.

The mantle contains these two other layers.

Convection Currents happen in the Earth because of heating and ___________________.

Evidence that has been used by scientists to confirm the composition of Earth's layers is:

Wegener gathered evidence including land features, _______, and climate change.

Continental Drift theory was that the continents were all __________________ at one time.

This is what happens when oceanic crust goes under continental crust.

The movement of the _____________________ produce Earth's magnetic field.

Which one is NOT used as evidence for sea-floor spreading?

The lithosphere is divided into parts called __________.

The theory of plate tectonics states that the plates are _______________.

Wegener's hypothesis was originally _________________ by his peers.

Sea-floor spreading starts when magma erupts along the _________________.

A boundary where the plates move past each other is called a _______ boundary.

Pangaea means _______________.

As you go further to Earth's center what happens to the pressure, temperature, and density?
