What is sedimentary, metamorphic or igneous.
When sediments go under compacting and cementing processes they become___________
Sedimentary rocks.
Rocks can be made of one or more of these.
What are minerals?
This is the type of rock that is pink, shiny and contains quartz, mica and feldspar.
What is pink quartz?
This is molten rock found above the earth's surface.
What is lava?
The final 2 processes that turn sediments into sedimentary rocks.
What are compaction and cementation?
Why are the layers of a metamorphic rock wavy, while sedimentary rock has straight, flat layers?
Metamorphic rocks have wavy, not straight layers due to heat and pressure
When igneous, metamorphic and sedimentary rocks go under weathering and eroding they become_________________
sediments
When a rock breaks down and the pieces are then dropped elsewhere.
What is deposition?
What shows us how different rocks change types.
Igneous rocks are categorized as _________ or _________, depending on where the molten rock cooled.
What are extrusive and intrusive.
This is called weathering.
When a rock breaks down and stays in one place.
Above or below the Earth's surface, where do metamorphic rock form?
Where is below the Earth's surface?

The bottom layers
__________ igneous rocks have larger crystals than the other kind of igneous rocks.
What is intrusive?
This type of sedimentary rocks form when dead plants from millions of years ago mineralizes. We use it to heat homes
What is coal or organic sedimentary rock?
what are parent rocks.
_________ and ____________ turn sedimentary rocks into metamorphic rocks.
Heat and pressure
A youngest rocks are laid on the ________
Top
The study of rocks, their history and the processes that form and change them.
What is geology?
An example of this type of igneous rock is the Stone Mountain in Georgia. This happens when magma cools above the Earth's surface.
What is an extrusion igneous rock?
When a rock breaks down and the pieces are carried away?
What is erosion?
Shale is the parent rock of this metamorphic rock.
What is slate?
