Minerals have what kind of structure?
crystalline
100
What is a rock composed of?
minerals, rock fragments, organic material, naturally occurring materials
100
What type of rocks are fossils formed in?
sedimentary
100
What is the rock cycle?
A cycle that shows how rocks form and change over time
100
Explain the difference between foliated and non-foliated rocks
foliated you can see the folds or planes in a rock, non-foliated you cannot
200
Can a mineral be made in a lab? Why or why not?
No, it has to be naturally occuring
200
Name the three types of rocks
igneous, metamorphic, sedimentary
200
Why cant a fossil be found in igneous rock?
Because of the extreme temperatures and which igneous rocks are formed
200
How are igneous rocks formed?
by the cooling of magma or lava
200
When Limestone is exposed to heat and pressure, what type of rock does it become?
Marble
300
Can a mineral be made from plant material? Why or why not
no, it has to be inorganic
300
What type of rock would you most likely find near a beach?
sedimentary
300
Sedimentary rocks found high in the Himalayan Mountains have been found with fossils of clams and other marine life. What does this indicate about the origin of the Himalayan Mountains?
The Earth's crust that formed these mountains was once covered with an ocean
300
How are metamorphic rocks formed?
When parent rocks are changed by heat and pressure
300
What type of rock would scientist study if they wanted to know more about the Earth's core?
metamorphic
400
Name four characteristics that define a mineral
naturally occurring, inorganic, solid, crystalline structure

Granite is a coarse or medium grained rock that is rich in quartz and feldspar. It is formed when bodies of magma cool and harden deep below the earth's surface. What type of rock is granite?
intrusive igneous rock
400
Why do only certain fossils exist?
The conditions for a fossil to form have to be perfect therefore not every organism will be fossilized when it dies
400
How are sedimentary rocks formed?
When sediments are deposited and compacted and cemented together
400
How is mineral grain size determined in an igneous rock?
How fast or quickly an igneous rock cools
500
Give me an example of a mineral
quartz, diamond, gold, topaz, etc
500
Marble is formed when intense heat and pressure is applied to limestone. What type of rock is marble?
metamorphic
500
Name one of the three types of fossils
mold, cast, or trace
500
Explain the process to go from an igneous rock to a metamorphic rock to a sedimentary rock
The igneous rock is formed by cooling magma, then exposed to heat and pressure and it becomes a metamorphic rock. Once it is weathered, its sediments are compacted and cemented to become a sedimentary rock.
500
explain the difference in weathering and erosion
weathering is breaking down the rock and erosion is moving it
