Which best describes earth's mantle? (1 point) a. it is made up of rock so hot that it flows. *my answer* b. because it is solid rock, it can not flow. c. it is made up of metal so hot it flows d. because it is solid metal, it can not flow.

The best description of Earth’s mantle is it is made up of rock so hot that it flows. This layer is also called the asthenosphere. This Earth’s mantle has a thickness that reaches 2,900 kilometers to wrap up the Earth’s core. It is a rocky layer that covers 84% of Earth's volume. Its composition is rich in magnesium with temperatures at the bottom of the mantle reaching 3,000 degrees Celcius. This condition induces the high temperatures of Earth’s mantle.

Further Explanation:

In the solar system, Earth is the third planet that is located close to the Sun, Mercury, and Venus. It is the only planet that can be used by all living creatures. Structurally, the Earth’s anatomy consists of three layers, namely;

1.Lithosphere, the outer part of the Earth as a place for all the living creatures that are covered by an atmosphere.

2.Asthenosphere, the rocky layer of the Earth that is located between Lithosphere and Core.

3.Earth’s Core, the dense center of the Earth and the surface temperature here is very high.

Each layer of the Earth not only has a different constituent material but also different structures and characteristics. This is what causes each layer to hold different tasks and functions.
