_____________________: The thin and solid outermost layer of the Earth above the mantle.
_____________________: The soft layer of the mantle on which the lithosphere (or tectonic
plates move.
_____________________: The layer of rock between the Earth’s crust and core. Much
thicker than the core and contains most of Earth’s mass.
_____________________: The solid, outer layer of the Earth that consists of the crust and
the rigid upper part of the mantle. It is divided into pieces called tectonic plates.
_____________________: A substance made of all the same atoms. O = Oxygen.
_____________________: The liquid layer of the Earth’s core that lies beneath the mantle
and surrounds the inner core.
_____________________: When two or more elements combine together in a certain ratio.
_____________________: The solid dense center of our planet.
_____________________: The process by which new oceanic crust forms as magma rises
toward the surface and solidifies.
_____________________: The boundary between two tectonic plates that are moving away
from each other.
_____________________: The boundary formed by the collision of two plates.
_____________________: The boundary between tectonic plates that are sliding past each
other horizontally.
