Question

The energy which is not derived from the sun is

• A. Biomass
• B. Fossil fuels
• C. Nuclear energy
• D. Geothermal energy

Answer 1

The correct option is C

Nuclear energy

The correct option is C.

Explanation of the correct option:

1. Nuclear energy is a type of energy which is due to the radioactivity in the certain elements.
2. This is a type of energy which is there when an unstable nuclei breaks into the smaller nuclei and so as a byproduct we will get the energy , and this process would be further known as Nuclear fission.
3. And when two light atoms will join together there would be a release of an enormous amount of energy and this process would be further known as Nuclear fusion.
4. So, this form of energy in not derivable from the sun's energy directly, it is just released during the nuclear fission or fusion.

Explanation for the incorrect answers:

Option A: Biomass

1. The fuel developed from natural and organic materials or wastes, which are a renewable and sustainable source of energy is known as Biomass.
2. It consists of the energy that is derived directly from the sun , as the plants will absorb the sun's energy for the photosynthesis process and there would be the conversion of different gases.

Option B:

1. Basically the fossil fuels are made up by the decomposition of the plants or the animals.
2. Because of the heat and the pressure coming there from the Earth's crust, decomposition will take place and fossil fuels are formed.
3. There would also be a energy conversion from the chemical energy of the sun to the heat energy.

Option D:

1. It is actually a type of thermal energy that's after generating is stored in the Earth's crust.
2. This is actually renewable in nature and is a kind of heat generated in the Earth only.
3. And basically this energy is just derived from the Solar energy (Energy from the sun).

Final answer: The energy which is not derived from the sun is nuclear energy.
