100
Made of one or more minerals.
What is rocks?
100
It covers about three-fourths of the Earth's land area and most of the ocean floors. Scientists can study our layers to discover how climates and environments have changed over millions of years.
What are sedimentary rocks?
100
A natural process that breaks rocks into smaller pieces.
What is weathering?
100
I am hot molten rock. You can find me in an underground chamber.
What is magma?
100
The two items needed to change sedimentary rock into metamorphic rock.
What are heat and pressure?
200
We form when great amounts of heat and pressure change other types of rock.
What is metamorphic rocks?
200
A mineral that has a hardness of 7 on the Mohs scale.
What is quartz?
200
We form when molten rock cools and freezes solid.
What are igneous rocks?
200
Bones and leaves.
What are fossils?
200
When heat is applied to sedimentary rock, it changes into this.
What is metamorphic?
300
Different kinds of crystals that make up rocks.
What are minerals?
300
I am hot molten rock that has erupted from a volcano. After I flow onto the surface of the earth, I will cool and freeze solid into igneous rock.
What is lava?
300
Small bits of rock, plant, and animal remains, and live animals.
What is soil?
300
An igneous rock that cooled very quickly.
What is obsidian?
300
One thing a scientist can tell from a fossil.
What is see teacher?
400
The process by which rocks are broken down into smaller pieces by wind, water, and ice.
What is weathering/erosion?
400
A very soft mineral.
What is talc?
400
I am the process by which rocks change over millions of years.
What is the rock cycle?
400
Melted rock that has cooled.
What is a property of igneous rock.
400
The rock with a 10 on the hardness scale.
What is diamond?
500
A common mineral that forms rocks.
What is mica?
500
We are tiny pieces of gravel, sand, and mud that settle to the bottom of lakes, rivers, and oceans. Over time, more layers will settle on top of us. the pressure and weight from the layers will push down and turn us into rock.
What are sedimentary rocks?
500
Made of layers.
What is sedimentary rock?
500
The type of rock that describes gneiss.
What is metamorphic?
500
The coolest person you know.
