instrument that records and detects earthquake waves.
Plates seperate
Divergent
Magmas that are high in silica are thick,light-colored and slow-moving
Felsic
The physical layer that is found under the mesosphere, which is made up of liquid metal.
Outer core
An earthquake that occurs before a larger seismic event and is related to it in both time and space.
Foreshock
3 types of Convergent Boundaries.
Oceanic/Oceanic,Continential/Continential,Continential/Oceanic.
Magmas that are low in silica, high in iron are thinner, darker and fast-moving
The chemical layer beneath the mantle, which is made up of metals.
Core
A smaller earthquake that follows a larger earthquake, in the same area of the main shock.
Aftershock
