What is formed when magma cools down and hardens?
Igneous Rock
What type of igneous rock is formed INSIDE the Earth?
intrusive igneous rock double points: Give an example.

rock cycle
What is an example of Igneous rock?
basalt, pumice, obsidian, granite.
What does metamorphic mean?
Changed shape, bonus points if you said the meaning was from the greek or latin word.
process by which the weight of overlying rock presses sediment together into a rock
compaction
What is weathering?
Weather breaking down rocks into fragments.
rock that is a source of soil; bedrock
Parent Rock
What does "ignis" mean in latin?
fire.
What rocks usually make metamorphic rock after heat and pressure?
Sedimentary rock
process by which minerals like quartz or calcite crystallize out of solution after the water is squeezed out by pressure thus packing or "gluing" together the nearby sediments
compaction and cementation
What are decomposers?
bacteria, fungi, and organisms that break down material.
