Two plates move apart creating a gap between them allowing magma to rise and form new lithospheric rock
What is a divergent boundary
100
The area along a fault at which slippage first occurs initiating an earthquake
What is focus?
100
An opening in the Earth's crust through which magma has reached the earth's surface
What are vents?
100
Molton rock that has cooled and solidified

200
The process of loosening and moving sediments
What is erosion?
300
The oceanic plate dives beneath the continental plate dragging the ocean crust along with it
What is subduction
300
The point on the earth's surface directly above the focus of an earthquake.

400
Transverse waves that move through the earth during an earthquake

400
Used as a measure for the energy released at the focus of an earthquake

400
Rock transformed from other rock as a result of heat, pressure or chemical processes
What is metamorphic rock?
400
The by-product of fossil fuel emissions reacting with water in the atmosphere

500
The crust, the mantle and the core
What are the layers of the earth?
500
The machines that are used to record data about earthquakes
What are seismographs?
500
Result from the Earth's entire mass shaking like a bell that has been rung with up and down and back and forth motion
What is surface waves?
500
Process to determine the absolute age of rocks
What is radioactive dating?
500
When water seeps into cracks of rocks and then freezes and pushes the rocks apart.
