Question

The biggest source of energy on Earth’s surface is

• A. Biomass
• B. Solar radiation
• C. Tides
• D. Winds

Answer 1

The correct option is B

Solar radiation

Correct Option: Option B

1. Sun (solar radiation) is the biggest source of energy on Earth’s surface.
2. It is also known as the ultimate source of energy on Earth’s surface because we know that green plants use sunlight for photosynthesis, which is the process by which they make food for their growth.
3. When the plants are eaten by the animals, they consume food made with the help of sunlight.
4. When these plants and animals die, their remains, which consist of material directly or indirectly made with the help of sunlight, get buried in the earth and converted into fossil fuels, such as coal and petroleum.
5. The energy that we store in batteries with the help of solar panels is also due to the sun. It also regulates the weather condition and the water cycle.
6. So, this option is correct.

Incorrect Options:

Option A

1. Biomass energy is the energy generated by living organisms or organisms that were once living.
2. This energy is very less when compared with solar energy.
3. So, this option is incorrect.

Option C

1. Tidal energy is the energy generated by oceans during high and low tides. It is a renewable source of energy.
2. This energy is very less when compared with solar energy.
3. So, this option is incorrect.

Option D

1. Wind energy is the energy generated by the flow of winds. It is commonly used to generate electricity using wind turbines.
2. This energy is very less when compared with solar energy.
3. So, this option is incorrect.

Therefore, Option B is correct.
