Rocks
This can cool and harden to form an igneous rock.
What is magma or lava?
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
The way light reflects off of a mineral; also known as metallic or nonmetallic.
What is luster?
How many different things make up a mineral?
One.
Name the three types of rocks.
What are sedimentary, igneous, and metamorphic rocks?
This kind of igneous rock is formed when magma cools beneath the Earth's surface.
What is intrusive igneous rock?
This rock is made up of many different layers.
What is sedimentary rock?
The two different types of luster.
What are metallic and non-metallic?
Talc and diamond are two minerals listed on Moh's Scale. Which one can be scratched by the other?
Talc can be scratched by diamond.
What is the difference between lava and magma?
Magma is inside the earth and lava is outside the earth.
Two of the things that can cause weathering. (Bonus points if you get both!)
What are water and wind?
The 2 things that cause metamorphic rocks to form.
What are intense heat and pressure?
Another way to identify minerals; it leaves the color of the powder behind when rubbed against a rough white tile.
What is streak?
The hardest mineral.
What is a diamond?
This type of igneous rock forms when lava cools on the Earth's surface.
What is extrusive igneous rock?
Rocks are made up of different...
minerals.
This rock is made from other rocks that weathered down.
What is sedimentary rock?
The property that determines how a mineral breaks.
What is cleavage?
A mineral that we put on food.
What is salt (calcite)?
The process where a rock breaks down into sediments.
What is weathering?
This is how a sedimentary or metamorphic rock can turn into an igneous rock.
What is melting into magma, then cooling into a rock.
Igneous rock that has fine-grained crystals.
What is extrusive igneous rock?
You can see this property just by looking at a mineral. Many minerals can be several of these. This is the least useful property.
What is color?
The scale that is used to measure the hardness of minerals.
What is the Moh's Hardness Scale?
Challenge: This is what pencil lead is.
What is graphite?
