What is the name of the process where rocks slowly change into different types over millions of years?
What is the rock cycle?
100
What is the most recognizable feature of sedimentary rocks?
They have layers.
100
There are two types of igneous rocks, what are they?
Intrusive and extrusive.

What is an example of an extrusive igneous rock?
What is obsidian?

What do you call a rock that is made from layers of sediments pressed and glued together?
What is a sedimentary rock?
200
What is the most recognizable feature of metamorphic rocks?
Wavy banded layers of mineral crystals.
200
What is the difference between erosion and weathering?
Weathering is what created sediments and erosion is where those sediments are moved by wind, water, or gravity.
200
What is an example of an intrusive igneous rock?
What is granite?

Name that rock!
Bonus point if you can name the specific type of rock.
Marble
Metamorphic rock
300
Write the definition of igneous rock?
A rock that forms when magma or lava cools and hardens, often forming crystals.
300
Where do sedimentary rocks form?
On top of the crust.
300
Describe how a sedimentary rock becomes metamorphic.
The sedimentary rock becomes trapped inside the crust, where it experience extreme heat and pressure which changes its composition without melting it. Now it is a metamorphic rock.
300
Share ALL facts about extrusive igneous rocks.
- Form above Earth’s surface
- Form from lava
- Cool quickly
- Have small crystals
- Can look smooth or glassy

Name that Rock!
Bonus point for name the specific type of rock!
Obsidian
Extrusive igneous rock
400
Write the definition of metamorphic rock.
A rock that forms when existing rock is changed by heat and pressure inside Earth (without melting).
400
Where do metamorphic rocks form?
Inside the crust
400
How does an metamorphic rock become an igneous rock?
First the metamorphic rock would get stuck in the mantle making it melt which turns it into magma. Then either it will cool in the mantle making it an intrusive igneous rock or the magma would go on top of the crust becoming lava before it cools into an igneous rock.
400
Share ALL facts about intrusive igneous rocks.
- Form below Earth’s surface
- Form from magma
- Cool slowly
- Have large crystals
- Usually have a rough/coarse texture

Name that rock!
Bonus point for naming the specific type of rock!
Granite
Intrusive igneous rock
500
Write the definition of cementation.
The process where minerals left behind from water glue sediments together to form rock.
500
Where do igneous rocks form?
They go under the crust and into the mantle but they can cool either under the crust or on top of the crust.
500
Describe how an igneous rock can turn into a sedimentary rock.
Igneous rock -> weathering -> sediments -> erosion -> deposition -> compaction -> cementation -> sedimentary rock.
500
What causes igneous rocks to have different textures? Explain your answer.
Cooling time causes different textures. Rocks that cool slowly have large crystals and a rough texture. Rocks that cool quickly have small crystals and a smoother texture.

Pumice!
Extrusive igneous rock
