100
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 is made of sediments, pebbles, and other sized rocks cemented together by minerals from water.
What is Conglomerate
100
The process by which one kind of rock changes to another
What is the rock cycle
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)
200
Force that squeezes rocks together
What is pressure
200
Sedimentary rocks are formed from sediments and pressed together in these
What is layers
200
True or False The rock cycle has one start and one stop
What is FALSE The rock cycle is never ending
200
The way a mineral shines or reflects light
What is luster
300
When an igneous rock cools slowly, the mineral grains are small or large
What is large
300
Types of rock that can be turned into a Metamorphic rock
What is Igneous and Sedimentary
300
Helps to create this rock (Think rock cycle0
Weathering and erosion
300
The difference between a rock and a mineral
What is a rock is made of many different elements, where a mineral is made of only one.
300
Measure how easily a mineral can be scratched
What hardness
400
Melted rock below the Earth's surface
What is magma
400
Metamorphic rocks can be melted down to magma and formed into
What is an igneous rock
400
The remains of animals or plants from long ago
What are fossils
400
True or False Igneous rocks can turn directly into a Sedimentary rock
What is FALSE (Has to be broken down into sediments first)
400
The tendency of a mineral to split easily along flat surfaces
What is cleavage
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
What are igneous rocks
500
The color of a mineral when it is ground to powder
What is streak
