The document describes the four main layers of the Earth from outermost to innermost: 1) the crust, made of rocks and soil, is the thinnest layer; 2) the thick, flexible mantle below is made of magma; 3) the outer core of melted nickel and iron; and 4) the inner core is solid iron, nickel, and alloy and experiences extreme pressure.
Layers of the earth
- 1. Layers of the Earth
- 3. 1. Crust - Earths outermost layer - Made up of soil and rocks - Thinnest among the other layers - 3-80 km thick - 870 Celsius
- 4. 2. Mantle - Thickest layer of the Earth - Made up of magma - 3000 km thick - Flexible (plastic layer) - 1600-4000 Celsius
- 5. 3. Outer Core -Composed of melted Ni and Fe -2890 km thick -4400 Celsius
- 6. 4. Inner Core - Composed of solid Fe, Ni, Alloy - 1222 km thick - 4400 Celsius - Metals are squeezed together (pressure)
- 8. 1. Earths outermost layer 2. Composed of solid Fe, Ni, Alloy 3. Thickest layer of the Earth 4. Composed of melted Ni and Fe 5. Metals are squeezed together
