Hotspot
A concentration of heat in the mantle capable of creating magma
Subduction
Is a Geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another
Trench
A depression in the seafloor produced by subduction process
Volcanic Island Arc
A chain of volcanoes that develop parallel to a trench

Seismograph
Instruments used to record the motion of the ground during an earthquake
Hypocentre/Focus
Is the point inside the earth where the earthquake started
Epicenter
The point on the earth directly above the focus or hypocenter.
Seismic wave
Are the waves of energy caused by the sudden breaking of rocks within the earth, such as an earthquake or an explosion.
Convergent boundaries
Where two tectonic plates collide
Divergent boundaries
Where two tectonic plates move away from each other
Transform fault
Is where two tectonic plates slide past each other
