Rock cycle Flashcards
what is sedimentation?
When minerals sink to the bottom of something, leaving the water/less dense things on top
what processes would create a metamorphic rock?
Brutal high temperatures and pressure
compactation
what processes create a igneous rock?
melting and cooling
where would you find extrusive igneous rock?
on the earth’s surface
where would you find intrusive igneous rock?
inside the crust

what kind of rocks are found deep within the earth where there is great heat and pressure?
metamorphic
What processes create a sedimentary rock?
weathering and erosion
transport and deposition
sedimentation
compaction and cementation

What are minerals?
the particles that make up a rock
Each mineral has its own _____, such as luster, color, hardness, and shininess
