Rocks
These types of rocks form from melted rock, either from magma or lava.
Igneous rocks
Evidence that an animal or plant lived long ago
Fossil
What is a layer of soil?
A horizon
What are energy sources that form starting millions of years ago?
Fossil fuels
Which rock is the softest of all rocks?
Talc
These rocks have layers.
Sedimentary rocks
What kind of fossil is pressed into the ground?
An imprint
The top layer of soil at the surface, rich with humus and minerals.
Topsoil
What is an example of a nonrenewable resource?
Coal, oil, gas, etc.
Name an example of sedimentary rock.
Sandstone or limestone
Which property of rock shows off a diamond's shine?
luster
What is a fossil formed in a shape or mold?
A cast
What is humus?
Non-living plant and animal matter.
What is an example of a renewable resource?
Wind, sun, water, etc.
Extreme heat and extreme pressure create what type of rock?
Metamorphic rock
Name two examples of igneous rocks.
obsidian and basalt
A hollow form with a certain shape is what?
A mold
What are spaces between soil particles?
Pore spaces
True or False: burned fossil fuels can pollute the Earth
True
This is how a metamorphic rock that was formed deep inside the Earth's crust ends up on the Earth's surface.
Uplift
Name the four properties of rocks.
Luster, streak, hardness, and color
What is part of an animal's body that is most likely to be preserved as a fossil?
A bone or tooth
Which would water go through faster (have a higher permeability): sandy soil or heavy clay?
Sandy soil
True or false: fossil fuels can be easily replaced
False
Describe the steps of the rock cycle
1. Weathering, erosion, deposition -> Sediment
2. Deposition/pressure -> Sedimentary rock
3. Extreme heat and pressure -> Metamorphic rock
4. Melting -> Magma
5. Cooling -> Igneous rock
6. Uplift... (-> the cycle continues)
