100
A lightweight rock with tiny holes and crumbly (Pumice, granite or sandstone)
What is pumice
100
Rocks formed by extreme heat and pressure deep inside the Earth
What are metamorphic rocks
100
This rock forms from sediments that are cemented or pressed together
What is sedimentary rock
100
The process by which one kind of rock changes to another
What is the rock cycle (p. 180)
100
Basic building block of rocks
What are minerals
200
Determines the size of the mineral crystals in an igneous rock
What is the speed at which it cooled down (Cools slowly, crystals are larger, cools quickly, crystals are small p. 153)
200
Force that squeezes rocks together
What is pressure
200
Sedimentary rocks are formed from sediments and pressed together in these
What are layers
200
True or False The rock cycle has one start and one stop
What is FALSE The rock cycle is never ending
200
Five physical properties of rocks (HINT: we made a chart of these in class on Monday!)
What are color, streak, hardness, cleavage and luster
300
Type of rock that forms from lava or magma
What is igneous rock
300
Rocks that form from igneous, sedimentary, or other metamorphic rocks
metamorphic rocks
300
True or False Sedimentary rocks are easily changed by wind and water
What is TRUE
300

300
Measure hardness using this scale
What is the Mohs' hardness scale
400
Melted rock below the Earth's surface
What is magma
400
Some uses of metamorphic rock
Buildings, statues, jewlery, glassmaking, ceramic, fuel (coal) (p. 176-177)
400
The remains of animals or plants from long ago (Hint:can be found within rocks)

The hardest mineral (cannot be scratched by any other)
What is a diamond
500
Magma that reaches the Earth's surface
What is lava
500
True or False Metamorphic rocks are formed from only sedimentary and igneous rocks
What is FALSE (They can also be formed from other metamorphic rocks. Physical and mineral make-up change p. 172)
500
True or False Layers of sedimentary rocks are always the same thickness
What is FALSE
500
Rocks that are formed when cooled and hardened
