Classifying Rocks
Igneous Rocks
Sedimentary Rocks
Metamorphic Rocks
The Rock Cycle
1
Geologists classify rocks into 3 major groups
What is igneous, sedimentary, and metamorphic
1
Igneous rock that formed from magma and cooled very slowly UNDERNEATH the earth's surface is called ________.
What is intrusive rock
1
These small rock pieces or particles make up sedimentary rock. They can be other rocks or plant and animal organisms
What is sediments
1
This is how metamorphic rocks are created.
What is extreme heat and pressure
1
What process turns solid rock into magma?
What is melting
2
The type of rock that forms from magma or lava cooling
What is igneous rock
2
This type of igneous rock is formed from lava ON the earth's surface.
What is extrusive rock
2
This type of rock is made of pieces of smaller rock
What is clastic
2
What types of rocks can become metamorphic rocks
What is igneous, sedimentary and other metamorphic rocks (ANY)
2
Choose from the list which ones are agents of both weathering and erosion
wind
temperature
ice
water
plants
What is wind, water, ice.
3
What rocks and made of
Minerals
3
How does the cooling rate of magma affect the crystal size in igneous rocks?
What is the slower the cooling, the larger the crystals. The faster the cooling, the smaller the crystals
3
Sedimentary rocks can form from sediments that have settled out of wind or water, a process called
Deposition
3
Where do metamorphic rocks form
Deep underground
3
What might happen to an igneous rock that gets buried deep underground and exposed to heat and pressure?
What is turn into metamorphic rock
4
95% of earth's crust is made out of this type of rock.
Igneous
4
This type of igneous rock is used to make countertops.
What is granite
4
This type of sedimentary rock you can find fossils in.
What is an organic sedimentary rock
4
A metamorphic rock arranged in layers is called
What is foliated
4
Sediments settle and build up in layers
What is deposition
5
a rock made the evaporation of water and crystallisation of minerals
what is chemical sedimentary rock
5
Explain why obsidian (volcanic glass) has no visible crystals, while granite has large crystals.
What is obsidian cooling too fast and igneous cooling too slow
5
This type of sedimentary rock is composed of fragments and pebbles of minerals and other types of rock.
What is clastic.
5
Which type of rock can become metamorphic?
What is any type of rock
5
Describe the full cycle from magma to sedimentary rock.
what is Magma cools → Igneous → Weathering and Erosion→ Sediment → Compaction and Cemenation→ Sedimentary
