Earth Layer Composition of the Earth Three layers
- Slides: 20
Earth Layer
Composition of the Earth • Three layers: – crust – mantle – Core • #5 Temperature and density increases as depth increases. •
Crust • #6. The composition of the earth changes with depth and layers. • #7. The crust is the upper part of the rigid lithosphere and is of different composition under land as opposed to the ocean floor.
Mantle • 66% of mass of Earth • #11 Below the rigid lithosphere, the mantle consists of hot rock of tar-like consistency, which slowly moves or flows.
Lithosphere #10 The Lithosphere is the coolest layer of the earth. • #12 The lithosphere is the smallest layer of the Earth and it comprises 1% of the Earth’s total mass.
Core • Hottest layer of Earth • 33% of the Earth’s mass • Made of – Outer core – Inner core
Inner Core • Inner core is solid • Inner core is more dense • The most dense layer of the earth
Outer Core • The Outer Core is molten
