Rockin' out
100
This can cool and harden and form igneous rock.
What is magma or lava?
100
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
100
The way light reflects off of a mineral.
What is luster?
100
A naturally occurring element, they form together to make many different rocks.
What are minerals?
100
These have provided the only information we have about what life was like on Earth millions of years ago.
What are fossils?
200
A person who studies the planet Earth and its history.
What is a geologist?
200
These are two ways that sediments are formed.
What is weathering and erosion?
200
Can be tested by holding a magnet on a string close to a mineral.
What is magnetism?
200
A fossil is ___________.
What is the imprint of an organism on a rock?
200
Name two ways people use rocks.
What is buildings, walls, roads, jewelry, decoration, countertops?
300
Different igneous rocks are formed by different forms of this.
What is lava?
300
These 2 things cause metamorphic rocks to form.
What are heat and pressure?
300
Another way to identify minerals; it leaves the color of the powder behind when rubbed against a rough white tile.
What is streak?
300
Where materials of the Earth's crust are loosened, dissolved, worn away or moved from one place to another by natural means.
What is erosion?
300
What happens if an igneous rock weathers? What type of rock does it turn into?
What is sedimentary rock?

What is a diamond?
500
This determines the size of crystals that form in igneous rocks.

500
Give an example of what sedimentary rocks are used for.
What is concrete, buildings, sidewalks, roads, bricks?
500
You can see this property just by looking at a mineral. Many minerals can be several of these.
What is color?
500
Describe what will happen after many years to sand and other sediment that has blown or washed to the ocean floor.
What is sediment will build up, compress together in layers and form larger rocks?
500
