the partially melted layer of the mantle that lies underneath the lithosphere

Type of plate boundary where plates slide by each other

The first waves to arrive at a station, they are the fastest, move back and forth and travel through solids and liquids

this is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced or sinks into the mantle.

an instrument that measures and records details of earthquakes, such as force and duration.

point on the surface where the earthquake originates

point on the FAULT beneath the surface where earthquake starts

The amount of energy released by an earthquake, measures how strong the earthquake is

The second waves to arrive at a station, they are the slowest, move side to side (shear) and travel only through solids

Type of plate boundary where plates collide

Type of plate boundary where plates move away from each other

A large wave created by an underwater earthquake

the crust and the upper portion of the rigid mantle is called

A crack in Earth's crust where movement has occurred

the transfer of energy in gases and liquids due to differences in density
