One who studies the solid of Earth.
The study of the solid of earth.
Material that forms earth’s hard surface.
The layer of rock the forms the earth’s outer surface.
A dark, dense igneous rock with a fine texture, found in oceanic crust.
A usually light colored rock that is found in continental crust.
Layer of the Earth just beneath the crust
A layer of molten iron and nickel that surrounds the inner core of the earth.
A layer of iron and nickel that is under so much pressure that it is believed to be solid.
A rigid layer made up of the upper most part of the mantle and the crust.
The soft layer on the mantle in which the Lithosphere floats .
The force exerted on a surface divided by the total area (over which the force is exerted).
The measurement of how much mass is contained in a given volume of a substance.
The name of the single land mass that drifted apart 225 million years ago and gave rise to today’s continents.
The hypothesis that all the continents slowly move across the earth’s surface.
The process by which oceanic crust sinks beneath a deep ocean trench and back into the mantle in a convergent plate boundary.
The under-sea mountain chain where new ocean floor is produced; a divergent plate boundary.
A deep valley along the ocean floor through which oceanic crust slowly sinks towards the mantle.
A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust.
The theory that pieces of earth’s lithosphere are in constant motion, driven by convection currents in the mantle.
A break or crack in the earth’s surface along which rock moves.
A plate boundary where two plates move away from each other.
A plate boundary where two plates move past each other in opposite directions.
A plate boundary where two plate move towards each other.
A deep valley that forms where two plates move apart.
A force that acts on rock to change its shape or volume
A change in the volume or shape of the earth’s crust.
The shaking that is produced by the movement of rock beneath earth’s surface.
A break or crack in the earth’s lithosphere along which rocks move.
a type of fault where rocks on either side move past each other sideways with little up and down motion.
A type of fault where the hanging wall slides downward; caused by tension in the crust.
The block of rock that forms the upper half of a fault.
A block of rock that forms the lower half of a fault.
A type of fault where the hanging wall slides upward; caused by compression in the crust.
A mountain that forms where a normal fault uplifts a block of rock.
A sinking or subsiding of a land surface as a result of geologic processes or of human activities.
A weak spot in the crust where magma has come to the surface.
An area where magma from deep within the mantle melts through the crust above it.
