Question:
What are the different layers of earth?
Sure, here are the different layers of the Earth, listed in point form:
- Crust
- Outermost layer
- Ranges in thickness from 5 to 70 kilometers
- Composed mainly of solid rock
- Where all life on Earth exists
- Mantle
- Layer beneath the crust
- Extends down to a depth of about 2,900 kilometers
- Composed of denser rock than the crust
- Responsible for most of the Earth’s mass
- Upper mantle is solid, while the lower mantle is partially molten
- Outer core
- Layer beneath the mantle
- Extends from a depth of about 2,900 to 5,100 kilometers
- Composed mainly of liquid iron and nickel
- Responsible for generating the Earth’s magnetic field
- Inner core
- Innermost layer of the Earth
- Extends from a depth of about 5,100 to 6,371 kilometers
- Composed mainly of solid iron and nickel
- Extreme pressure and temperature at the Earth’s center causes the inner core to be solid
