According to the theory of Plate Tectonics, this is where most active volcanoes occur
What is at plate boundaries
100
Geological theory that states that the Earth's lithosphere is divided into plates that are constantly moving
What is plate tectonics
200

The pattern for pressure as you go deeper into the Earth

What is pressure increases

Type of plate that divides

What is divergent


200

A super continent containing all of Earth's land that existed about 225 million years ago.

Composed mostly of iron and nickel

what is inner core


300
Type of tectonic plate boundary which involves a collision between two tectonic plates
What is convergent
300
Results when thinner, more dense, oceanic crust is pushed under less dense continental crust
What is subduction

what is magnetic field

500

The name of the transform fault, located in California, which causes an average of 10,000 earthquakes each year

What is the San Andreas Fault

500
When a continental plate and an oceanic plate converge, the type of plate that is subducted and why
What is oceanic because it is more dense
