Question

Energy from various sources is considered to have been derived from sun
Analyse the above statement and validate it with examples.​

Answer 1

Answer:

Yes, I agree with the statement that energy from various sources is considered to have been derived from the Sun. Sun is the ultimate source of energy. All forms of energy are directly or indirectly derived from the solar energy.

Wind energy: Due to uneven heating of the Earth’s surface by the sun rays at two different adjoining places, a pressure difference is created and wind is produced.

Wave energy: Strong winds are generated due to the Sun and the waves are generated by strong winds blowing across the sea.

Ocean thermal energy: The difference between the water at the surface and the water at a depth in seas and oceans is due to the Sun.

Energy from fossil fuels: Fossil fuels such as coal and petroleum are formed when large plants and ancient creatures are buried deep inside the Earth’s crust under the effect of a lot of pressure and heat.

Solar energy: The phenomenon of generation of electricity by light (photoelectric effect) is possible only in the presence of Sun.

Biomass: Plants convert the solar energy into chemical energy with the help of inorganic substances such as air and water.  These plants are consumed by the animals which produce wastes from which energy is obtained.

Energy from flowing water: Water from sea and rivers evaporate and fall at different places of the Earth in the form of snow and rainfall. This water is collected in a dam and when allowed to flow rotates the turbine of the generator and electricity is produced.

Answer 2

The above statement is true

Explanation:

Energy is the main source to do any particular work. It is highly essential, and the energy from different sources is generally considered to have obtained from the sun that provides solar energy or light energy.

Some of the energy provided by the sun is as follows-

• Solar energy- It is directly obtained from the sun, which is basically used in the conversion of light energy into electrical energy. For example, solar panels.

• Wind energy- It is caused due to the unequal heating of the surface of the earth, causing differences in pressure and generates wind.

• Wave energy- Wind is the main factor that causes friction with the surface of the oceans, generating wind with varying intensities.

• Biomass- Here, solar energy plays an important role in converting into chemical energy in the presence of inorganic materials.

• Fossil fuel energy- Heat and pressure play an important role here in the formation of fossil fuels that are major necessities in today's world.

Thus, the given statement is true.
