Will there be light if there is no sun?

Without sunlight, it would be completely dark on earth. We owe our daylight to the fact that every square meter on the sun shines brighter than a million light bulbs. Once sunlight hits the earth, it scatters in the atmosphere.

What energy does not need the sun?

GEOTHERMAL ENERGY
GEOTHERMAL ENERGY This form of energy is not generated by the Sun. It is made by the nuclear reactions taking place all the time deep inside the Earth.

Is moon a source of light?

Moon doesn’t have its own light and it either reflects or refracts the light of the sun. Hence it can be said that the moon is not the natural source of light. Therefore, the statement ‘the moon is a natural source of light’ is false.

What if there was no sun essay?

If there is no sun then there will be no any life in the earth because Sun is the source of energy and without energy we should die. So sun is very much necessary for us for being live. The sun is very powerful and unique and life of all living things in this universe will come to a stand still with out the sun.

What will happen if sun disappeared?

With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s surface would die soon after.

Why is sun the main source of energy?

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.

What are 5 sources of light?

Examples of natural sources of light

• Sun.
• Stars.
• Lightning.
• Fireflies.
• Glowworms.
• Jellyfish.
• Angler fish.
• Viperfish.

Is Mirror a source of light?

Most recognise natural and artificial light sources to be emitters of light and many also believe that bright and shiny objects like mirrors are also sources of light. An important reason for this is that students’ conscious experiences of ‘reflection’ are associated with mirrors and other shiny smooth surfaces.

What would happen if the Sun disappeared?

If the sun was still there, but just stopped emitting light and heat, we would stay in orbit. All of Earth would be in permanent darkness; the air and oceans would retain warmth for some time, but all life would eventually freeze to death.

Why there is no light of sun in space?

In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Since there is virtually nothing in space to scatter or re-radiate the light to our eye, we see no part of the light and the sky appears to be black.

What is the main source of light energy on Earth?

The Sun is a very important source of light energy. Without the energy from the Sun, there would be no plants or animals on Earth’s surface. Besides the Sun, other sources provide light. Burning objects give off light.

Why Sun is the best source of energy for our body?

So, for gaining this energy for free, Sun is the best provider of this nutrient. The light energy we get from the sun can be utilized for domestic purposes like we can use these for operating solar cookers. We also find the use of sunlight for solar water heaters. Light is the only source that helps us see beautiful things around us.

What would happen to the Earth without the Sun?

Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe. The earth’s position in the solar system is optimal for the development of life. It is exactly the right distance from the sun.

What are the things in nature that emit light?

The following things in nature have the ability to emit light: The Sun is the major source of light for the earth. The sun is a massive ball of fire, at the centre of which nuclear fusion produces massive energy. This energy comes out as heat and light.
