Match the layer of the earth with its best description.

1. inner core a. plastic portion of the upper mantle of the earth
2. outer core b. made of large plates that move
3. lower mantle c. layer just outside of the outer core
4. upper mantle d. thin, rigid surface of earth
5. crust e. layer that includes the asthenosphere
6. lithosphere f. made of solid iron
7. asthenosphere g. very dense liquid of iron and sulfur

1. The inner core of the Earth is composed of the solid iron. Hence, it can be matched with the point (f).

2. The outer core of the Earth is composed of very liquid made up of the sulfur and iron. Hence, this can be matched with the point (g).

3. The lower mantle layer is the layer which is present just outside the outer core layer. Hence, this can be matched with the point (c).

4. The upper mantle layer of the Earth consists of large plates. These plates can move and change their position. Hence, this can be matched with point (b).

5. The crust layer is the rigid and thin layer. Hence, it can be matched with the point (d).

6. The lithosphere layer includes the asthenosphere. Hence, it can be matched with the point (e).

7. The asthenosphere is the part of the Earth which is present in the Earth's upper mantle. Hence, this can be matched with point (a).

option c is the correct answer.
