Study Notes

Earth's Layers Study Notes

Inner Core: Composed of solid iron and nickel, located at the center of the Earth.
Outer Core: A liquid layer surrounding the inner core, also made up of iron and nickel, contributing to Earth's magnetic field.
Mantle: Situated above the outer core, filled with molten rock (magma) and composed mainly of silicate minerals; plays a key role in tectonic activity.
Crust: The outermost layer of the Earth, composed of solid rocks and silicates, varying in thickness; it's where all terrestrial life exists.
Lithosphere: A rigid layer that includes the crust and the uppermost part of the mantle, essential for tectonic plate dynamics.
Asthenosphere: The layer beneath the lithosphere that behaves plastically, reducing friction and allowing tectonic plates to move.
Mesosphere: A solid layer of the mantle characterized by increasing pressure and temperature as depth increases, contributing to mantle convection.
