Rocks, Rock Cycle
and Layers of the
Earth Review
Igneous Rock
Forms when hot
liquid/magma cools and
hardens
Sedimentary Rock
Forms when rocks are
broken down into smaller
pieces and harden
Metamorphic Rock
Forms when rock is
heated or squeezed
Rock Cycle
Continual process by which new
rocks form from old rocks
Rock
Solid mixture of crystals
of one or more minerals
Weathering
Breaking of rocks into
smaller pieces
Erosion
Wind, Water, and Ice
break off and carry grains
of rock
Deposition
Process of water, ice, and gravity
dropping newly formed sediments
Composition
Chemical make up of an
object or combo of
minerals made of
Lithosphere
Crust and Upper Mantle
of the Earth
Lithosphere
Asthenosphere
Region below the
Lithosphere
Mantle
Portion of Earth between
Crust and Core
Upper, Middle, and
Lower
Outer Core
Liquid portion of Earth’s
Core closer to Mantle
Inner Core
Solid portion of Earth’s
Core; Very Center of Earth
