Question

Match each Earth layer with the correct description. 1. inner core layer immediately outside the inner core; composed of liquid iron and sulfur 2. outer core innermost layer of the two mantle layers; composed of rock and cooler than the core 3. lower mantle outermost layer of the two mantle layers; includes the asthenosphere and lower lithosphere 4. upper mantle innermost region of the earth; composed of solid iron 5. crust the outermost layer that forms the surface of the earth

Answer 1

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:

1. Inner core is innermost layer of the earth. It is the hottest layer of Earth.
2. Outer core is above the inner core and it exist in liquid form. The circular movement of liquid generates Earth's electromegnatic field.
3. Lower mantle is the largest layer of Earth and is made up o two mantle layers.
4. This layer lies above the lower mantle and below Crust.
5. 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.

Answer 2

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
