Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
All of the following are true about the Sun EXCEPT
A
the Sun makes the light we see
B
the heat from the Sun is reflected from Moon to the Earth
C
sunlight is Earth’s primary source of energy
D
None of the above
Explanation: 

Detailed explanation-1: -The sun is a big ball of gas and plasma. Most of the gas 91 percent is hydrogen. It is converted into energy in the sun’s core. The energy moves outward through the interior layers, into the sun’s atmosphere, and is released into the solar system as heat and light.

Detailed explanation-2: -The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface.

Detailed explanation-3: -We refer to the moon’s power of reflecting heat. It need hardly be said that the reflection and the radiation of heat are very different matters.

Detailed explanation-4: -Unlike our Sun, the Moon doesn’t create its own light. We can only see it because light from the Sun is reflecting off of its surface.

Detailed explanation-5: -The heat source for our planet is the sun. Energy from the sun is transferred through space and through the earth’s atmosphere to the earth’s surface. Since this energy warms the earth’s surface and atmosphere, some of it is or becomes heat energy.

Detailed explanation-6: -It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
