Rock Cycle/Miscellaneous
This is how Igneous rocks form
What is cooling and crystallization of magma or lava?
When a mineral breaks in flat, even sheets
What is cleavage?
when magma cools inside the earth
What is an intrusive igneous rock?
How sedimentary rocks are formed
What is compaction and cementation?
two things do you need to get a metamorphic rock
what are heat and pressure
How sedimentary rocks form
The 5 criteria for a solid to be classified as a mineral.
Naturally occurring, inorganic, definite chemical composition, solid and a crystal structure
What rock types have a fine texture and little to no crystals
what are extrusive rocks: basalt, pumice and obsidian?
fossils are primarily found here
sedimentary rocks
If you add enough heat and pressure to shale (mudstone) you would get this metamorphic rock
What is slate?
The two things you need to get a metamorphic rock
What is heat and pressure?
Used as sheetrock or drywall
What is gypsum?
Which rock has large crystals or a coarse texture
What is Granite- Intrusive Igneous
how sediments form
What is weathering and erosion?
With enough heat and pressure added to limestone you will get this metamorphic rock
What is marble?
The ore mineral mined for iron
What is hematite?
Used as an additive in food
What is halite?
a short cooling time (extrusive) creates this
What is fine texture or small crystals
Marine fossils near the coast would most likely be found in this rock.
What is sandstone?
DAILY DOUBLE: Two non-foliated rocks
What are marble and quartzite?
which extrusive Igneous rock is called volcanic glass
What is obsidian
_________ and __________ are the two most common elements on earth
What are oxygen and silicon
Which Igneous rock would float in water
What is pumice
When rocks cement together with no chemical change.
What is clastic?
This foliated rock has "nice" lines
What is gneiss?
