Earth's Inside Flashcards
Name the 4 layers of the Earth, from farthest from the center, to the closest (the “center” isn’t a layer)
- Crust
- Mantle
- Outer core
- Inner core
What are the two pieces of evidence that geologists use to study Earth’s interior?
Direct evidence from rock samples, and indirect evidence from seismic waves.
What is the core mostly made of?
Iron and nickel
__________ and ____________ increase from the crust inwards.
Temperature and pressure
What gives us our magnetic poles?
The movement of the liquid outer core.
Explain the Earth’s crust
The crust is Earth’s outer shell/layer that’s definitely the thinnest. It is made up of oceanic and continental crust.
Explain the Earth’s mantle
The mantle is the squishy but hard layer of Earth. It’s made of hit but solid rock, and is divided into the Lithosphere and Asthenosphere.
Explain the Earth’s outer core
The outer core is the liquid layer of the core, made of Iron and Nickel.
Explain the Earth’s inner core
The inner core is the solid layer of the core, made of Iron and Nickel.
