Earth's Layers
What are Earth's 4 layers?
Crust, Mantle, Outer Core, Inner Core
What is weathering?
Breaking/wearing away of rock.
How is sedimentary rock made from sediment?
compaction and cementation
What happens to Earth's temperature, density, and pressure as you get closer to the center of Earth?
They all increase.
What is sediment?
Smaller pieces of broken rock.
How is igneous rock or sedimentary rock turned into metamorphic rock?
heat and pressure
What is magma called on the surface/above ground?
Lava
What is erosion?
Movement of sediment from one location to another.
How is magma/lava turned into igneous rock?
cooling and hardening
What is responsible for Earth's Magnetic Field?
Relationship between the Outer and Inner Cores.
What is deposition?
The settling of sediment.
What type of rocks can make sediment?
Igneous, sedimentary, and metamorphic rocks can all make sediment through weathering.
How is Earth's Layers divided?
by their density and composition
Is wind strong enough to move a large rock and break it?
Yes. For example, winds in a tornado are strong enough to accomplish this.
What type of rocks can turn into magma?
Igneous, sedimentary, and metamorphic rocks can all turn into magma by melting.
