geologic time scale shows the most amount of time that has gone by since earth was formed
core the innermost zone of the earth. the core has two parts: a solid inner core and a molten outer core
mantel surrounding the core, made mostly of solid rock
asthenosphere the part of the mantel that lies just below the lithosphere (slowly flowing rock (in mantel))
lithosphere a thin, rigid layer of rock, the outer most layer of the earth. contains the rigid upper mantel and the crust
crust solid surface of the earth
tectonic plates large broken pieces of lithosphere that move
plate boundaries the edge of the tectonic plates
-convergent boundary two plates are pushed toward each other, one of the plates will be pushed deep into the mantel
divergent boundary two plates are moving away from each other, causing a gap that can be filled wit magma, and when the magma cools, new crust is formed
transform fault boundary two plates slide from each other, also called transform boundaries
volcanoes mountains formed by magma from the earth's interior
earthquakes the result of vibrations (often due to plate movements)
