Rock clues to what' s inside the earth
certain rocks are found in different places on the Earth's surface

The speed of waves depends on the density and nature of the material they travel through.
the liquid layer of the Earth's core that lies beneath the mantle and surrounds the inner core
The layer of hot, solid material between Earth's crust and core.
The layer of rock that forms Earth's outer surface.
the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle

A plate boundary where two plates move toward each other.
sliding plate boundary
two plates move past each other in opposite directions
a process by which the end of one plate is forced below the edge of another
when the force of gravity moves a plate downward and away from a ridge
the pulling of a tectonic plate as its edge subducts deep into the mantle
age of mountains
can be determined by how much erosion and weathering has occured
parallel ridges that form where blocks of crust move up or down along faults
When rock layers are squeezed together and pushed upward.
form when blocks of Earth's crust are pushed up by forces inside Earth
mountains that form when molten rock erupts onto the earth's surface
The balancing of the downward force of the crust and the upward force of the mantle.
