Question

The sun is the _______ source of energy.

• A. primary
• B. secondary
• C. both $A$ and $B$
• D. none of the above

Answer 1

The correct option is A primary

The Sun provides solar power directly it is the primary source of energy. It also feeds plants through photosynthesis, which creates coal and oil (either directly as plant remains, or indirectly as animals remains — animals eat the plants). The Sun also causes evaporation of water, causing rain, which replenishes lakes, which drive hydroelectric power. The Sun even drives the weather on Earth, so it’s responsible for wind energy.
