Weather/Erosion/Deposition
The breaking down of rocks into smaller pieces
weathering
Igneous rock will most likely form out of a
volcano
What could wash away sediment and carry it?
ocean, rain, river, waves...
Is coal a sedimentary rock?
Yes
Can an igneous rock become a metamorphic rock before it becomes a sedimentary rock?
Yes... if it goes through heat and pressure
Dropping of sediment in a new place is called
deposition
What colour is igneous rock most likely to be?
black
Sediment forms which type of rock?
Sedimentary rock
How would a sedimentary rock form a metamorphic rock?
If it went through heat and pressure
How does a metamorphic rock turn back in to magma?
The movement of weathered rock
erosion
Once molten rock reaches the outside of a volcano it is called
Lava
Which type of rock can turn back into sediment?
All of them!
How does sediment form a sedimentary rock?
it must become compacted by pressure
What are the main causes of the formation of an igneous rock?
Heat and pressure
Waves crashing on a rock for an extended period of time is an example of
weathering
magma
Name 3 types of weathering that could happen to a rock
acid rain, waves, wind, sand blowing, freezing water in cracks, roots, glacier scarping
Describe what a sedimentary rock might look like...
it might have stripes from different layers of sediment, or it might look like little rocks clumped together
Describe what a metamorphic rock might look like...
wavy or curvy lines in the rock
Which rock would not be common to see on Earths surface?
metamorphic rock
What type of igneous rock is commonly used on countertops?
Granite
Explain why sedimentary rocks are often formed in water
Because sediment piles up on the bottom or rivers and lakes, and it gets pressed down by the weight of rocks above it.
What type of metamorphic rock is commonly used on countertops?
Marble
