Question
Most of the energy used on Earth comes from___________.
- Moon
- Sun
- Stars
- Ocean
Hint:
Solar energy is the most important energy.
The correct answer is: Sun
The correct option is b)Sun.
The sun's energy is the original source of most of the energy found on Earth. We collect solar thermal energy from the sun, and sunlight can also be used to generate electricity from solar cells (photovoltaics). The sun heats the surface of the earth, which in turn heats the air above it, creating wind. The water evaporated by the sun becomes clouds and rain, giving us streams and rivers to flow. Both wind and water flow (hydroelectricity) are sources of energy. The sun is the source of many types of energy that occur in nature. This type of energy is all around us. They are produced quickly and are constantly replaced as they are used.
