A minerals must be ____________, or not made of living things.
A minerals must be ORGANIC, or not made of living things.
100
What is the difference between magma and lava?
Magma is underneath the Earth's surface and lava is above the Earth's surface. They are both forms of liquid, molten rock.
100
What are the little pieces of rocks, pebbles, mineral grains, or rock fragments called?
Sediments
100
Metamorphic rocks form (above or below) the Earth's surface.
Metamorphic rocks form BELOW the Earth's surface.
100
What is the hardest mineral?
Diamond
200
What is the property that describes the way light reflects off of a mineral?
Luster
200
I form when magma slowly cools underneath the Earth's surface, what am I?
Intrusive igneous rock
200
How are sediments created and transported?
Weathering and Erosion
200
What two processes have to occur in order for a sedimentary rock to form a metamorphic rock?
Heat and Pressure
200
If fossil A is found ABOVE fossil B, which one is probably younger?
Fossil A
300
What is the name of the property you look at when you rub a mineral against a ceramic plate?
The streak
300
I form when lava cools quickly above the Earth's surface, what am I?
Extrusive igneous rock
300
Name the five steps it takes for extrusive igneous rocks to form sedimentary rocks
Weathering, Erosion, Deposition, Compaction, Cementation
300
What do we call the process of rocks changing from one kind of rock to another over time?
The Rock Cycle
300
Name 2 ways that rocks are classified.
Rocks are classified by grain size, texture, and how they formed (origin)
400
When you try to scratch a mineral with a nail, a penny, and other objects, what property are you testing?
The hardness
400
What size crystals form in intrusive igneous rocks? Why?
Intrusive igneous rocks have LARGE crystals or grains. The form like this because magma takes a LONG time to cool
400
Why can't fossils be found in igneous rocks?
The magma or lava would disintegrate or dissolve the organic remains instantly.
400
What type of rock was Gneiss before it underwent heat and pressure?
Granite
400
Name the five out of the six mineral identification tests.
Luster, hardness, color, streak, density, cleavage and fracture
500
Name 3 other mineral identification tests other than streak and hardness.
Luster, cleavage and fracture, density, color
500
What determines the size of the crystals or grains that form in igneous rocks?
The amount of time it takes for the magma or lava to cool
500
How are fossils formed in sedimentary rock? Walk through each of the five steps of sedimentary rock formation process.
Sediments are weathered off of rocks and eroded. As they deposit on the ground, an organism can die and become buried in the sediment. Over time, more sediments pile up and compact, then cement; creating sedimentary rock.
500
When does the rock cycle end?
Never! Rocks are continuously changing from one type into another.
500
How do fossil fuels form?
Fossil fuels form when organisms die and their organic material collects and creates coal, oil, or natural gas.
