Rock Transformations
Can rocks be formed as different types or are they all the same? Why?
Rocks can form in different ways. This causes them to be different types.
What is sedimentary rock?
Sediment that has been compacted and cemented together.
What is igneous rock?
Igneous rock is magma that has cooled and hardened.
Where is the impact from energy from the sun felt?
On Earth's surface
Where is the impact of energy from Earth's interior felt?
The mantle
Can rock on Earth's surface travel below Earth's surface? If so, how?
Yes. When plates move toward each other, rock from one plate move down below Earth's surface.
How is sedimentary rock formed?
Sedimentary rock forms when sediment is placed under pressure (compacted) and sticks together to form one solid (cemented).
How is igneous rock formed?
Igneous rock is formed when hot magma has cooled down and hardened.
What process happens as a result of energy from the sun?
Weathering
What process happens as a result of energy from Earth's interior?
Melting
Can rock below Earth's surface travel above Earth's surface?
Yes. When volcanic eruptions occur, magma can force its way up to the surface.
Yes. As plate move away from and toward each other, they may push deep-buried rocks up toward the surface.
Can sedimentary rock turn into igneous rock? If so, how?
Sedimentary rock can turn into igneous rock. If sedimentary rock is exposed to energy from Earth's interior, it can melt. As it melts, it becomes magma. Once the magma has cooled and hardened, it is considered igneous rock.
Can igneous rock turn into sedimentary rock? If so, how?
Igneous rock can turn into sedimentary rock. If igneous rock is exposed to energy from the sun, it will be weathered and broken down into pieces of sediment. Over time, the sediment can become compacted and cemented together to form a sedimentary rock.
What is created by processes driven by energy from the sun?
Sediment
What is created by processes driven by energy from Earth's interior?
Magma
How does sediment become sedimentary rock?
Sediment undergoes pressure (compaction) and gets stuck together (cementation) to become sedimentary rock.
How does magma become igneous rock?
