1. a. Lithosphere
If we divide the Earth into layers by their composition, then there are three of them, the crust, mantle, and core. The crust is the thinnest layer, being on the top, and being solid. The mantle is the second layer, lying between the crust and the core. It is a layer where the temperature and pressure are higher, and the rocks are hot and slow-moving. The core is the bottom layer, in the center of the planet. It is the hottest and has the highest pressure, being the densest of the layers and is composed mostly of iron and in lesser percentage of nickel.
2. b. Crust
The Earth is divided into several layers depending on the layers being solid or liquid. There are five different physical layers, lithosphere, asthenosphere, mesosphere, outer core and inner core. The lithosphere and the inner core are the two layers that are solid, thus the layer on top and the layer in the center. The asthenosphere, mesosphere, and outer core are all liquid, though it is a different degree of liquidity, and it is these three layers where the convection currents occur and cause the magnetic field of the Earth, as well as the tectonic movements.
Answer:
The temperature of the earth is first heated by the presence of the earth internal factors and then by the external factors.
Explanation:
- <u>All the gases in the atmosphere cannot absorb the entire radiation given from the sun directly, so the earth's surface gets heated directly first and then re-radiated back to the sky.
</u>
- The Water vapor and carbon dioxide are known as the primary reason for the heating of the earth's atmosphere form the below and they tend to trap the amount of the solar heat and thus heat the surface-atmosphere first and they then give output of this energy in the form of the long waves radiation and thus influences the temperatures of the earth at the night time. Thus forming a greenhouse effect of gases.
- <u>The villain is the carbon dioxides that gets accumulation the atmosphere and thus ends up heating up of the air </u>
