1) Fill out the process for each arrow in the diagram. Pay special attention to the direction the arrow is pointing. (9 pts) Cooling weathering
melting
Pressure and high heat
Weathering Compaction Pressure and high heat
weathering
melting
2) Complete the table, clicking on the link to see a 3D model of the rock sample (15 pts)
Sample
Two observations about the rock
Classification
How did the rock form?
What are two changes the rock could undergo next?
Igneous
Metamorphic
Sedimentary

-Blotches of different colors -No form of layers -Seems quite hard -Has layers -Looks soft/crumbly -Lightly colored
This rock formed through the cooling of magma This rock formed through the combination of both high pressure and heat from other forms of rocks This rock formed through the deposits or “sediments” of pre-existing rocks Either weathering into sediments or melting into magma Either weathering/ erosion into sediments, or melting into magma Either weathering into sediments, or heating/pressuring up into other forms of rock.
