When magma pushed up from the mantle cools and hardens into rock.
What is crystallization?

Mrs. Radel calls this process "Mother Nature's glue" since layers of sediments are packed down so tightly that the sediments are glued together.
What is cementation?
100
This metamorphic rock is foliated so it splits easily into thin sheets to make roof shingles, chalkboards, pavement stones, and flooring.
What is slate?

At this stage of the rock cycle, sedimentary, igneous, and metamorphic rocks form magma.
Hint: 1 Word
What is melting?

This igneous rock called obsidian is found above the earth's surface.
Intrusive or Extrusive Rock?
extrusive rock
200
Magma that reaches the Earth's surface.
What is lava?
200
The dropping of sediment from wind or water that slows down or from ice that melts.
What is deposition?

Metamorphism is caused by these 3 main causes.
What is heat, pressure, and hot water?
200
At this stage of the rock cycle, magma cools and becomes igneous rock.
Hint: 2 Words!!!
What is cooling and solidification?
200
Granite forms from magma---so is it extrusive or intrusive rock?
Intrusive Rock
300
Magma that hardens within the Earth's crust.
What is intrusive rock?
300
The process when layers of sediment build up over millions of years. As each layer forms, it weighs upon the lower layers and packs down the sediment.
What is sedimentation?
300
This metamorphic rock is used in buildings and statues. The famous Taj Mahal in India is made of this.
What is marble?
300
At this stage of the rock cycle, all three rock types (igneous, sedimentary, metamorphic) are broken up into sediments that are carried away and then dropped.
Hint: 3 words!!!!
What is weathering, erosion, and deposition?
300
This kind of rock cools very slowly and the crystal grains become large.
What is intrusive rock?
400
Lava that hardens on the Earth's surface.
What is extrusive rock?
400
The process of breaking rock into smaller pieces. Examples of this are: flowing water, moving ice, freezing & thawing, and growth of plants.
What is weathering?

The metamorphic rock schist has this mineral in it that is used for the "lead" in pencils.
What is graphite?
400
At this stage of the rock cycle, sediment is packed together and sticks to form sedimentary rock.
Hint: 2 words
What is compaction and cementation?
400
Diorite is a rock with large black and white crystal grains that are easy to see. Would this rock be intrusive or extrusive?
Intrusive rock
500
The Greek god of the world below that intrusive rock is named after.
Who is Pluto (for plutonic rock)?
500
This type of sedimentary rock is used to make bricks, tiles, pottery, and china.
What is shale or mudstone?
500
These type of rocks have bands or layers you can see. Examples: slate, phyllite, schist, gneiss
What are foliated rocks?
500
In this stage of the rock cycle, all three rock types (igneous, sedimentary, metamorphic) are changed into metamorphic rock.
Hint: 2 words!!!
What is heat and pressure?

Pumice is a rock with holes in it from the air bubbles present when the lava cooled. Is it intrusive or extrusive rock?
