Rock CycleA model that shows how rocks
are created and changed from one type to another.
Magma
Melted rock that is inside the earth.
LavaMelted rock that is on top of the earth’s surface
Sedimentary RockRocks made from layers of
weathered bits of shells, rocks, and minerals.
Igneous RockRocks that are formed when
melted rock from inside the earth cools and hardens.
Metamorphic RockRocks that form when existing rocks
are heated and squeezed deep inside the Earth.
Compact/CompactionWhen layers of sediment are closely and
firmly packed together. Usually due to the top layers putting pressure on the layers underneath.
SedimentTiny bits of broken shells,
rocks, and mineral grains.
WeatheringThe breaking down of rocks, soil,
and minerals by exposing them to water, oxygen, wind, ice, and other outside forces.
ErosionWater, wind, ice, or gravity carry and
move bits of broken rock from one place to another.
ProductA physical “thing” that has weight and takes up space. (noun)
Examples of products of the rock cycle:MagmaSedimentary rock
ProcessAn activity, action, or force that create products. (verb)
Examples of processes of the rock cycle:

DepositionWhen rock fragments are laid down in a new location.
