Answer:
1. Inner core -> innermost region of the earth; composed of solid iron.
2. Outer core -> layer immediately outside the inner core; composed of liquid iron and sulfur
3. Lower mantle -> innermost layer of the two mantle layers; composed of rock and cooler than the core
4. Upper mantle -> outermost layer of the two mantle layers; includes the asthenosphere and lower lithosphere
5. Crust -> the outermost layer that forms the surface of the earth
Explanation:
- Inner core is innermost layer of the earth. It is the hottest layer of Earth.
- Outer core is above the inner core and it exist in liquid form. The circular movement of liquid generates Earth's electromegnatic field.
- Lower mantle is the largest layer of Earth and is made up o two mantle layers.
- This layer lies above the lower mantle and below Crust.
- Crust is the foremost upper layer of Earth on which all forms of life exist. It exist in solid form and thus comprised of rocks and mountains.
