because without the sun it would be total darkness and we would all die.
The Sun is essential for life on Earth because it provides energy for photosynthesis, which is the process plants use to produce oxygen and food. Without the Sun's energy, Earth would be too cold and dark to support life as we know it.
Life on Earth benefits from the fusion reactions occurring in the sun by providing the energy that sustains all living organisms through photosynthesis. The sun's fusion reactions also help regulate Earth's climate by providing warmth and driving weather patterns that are essential for maintaining a habitable environment.
The primary source of light and heat energy for Earth is the Sun. The Sun's radiation travels through space and reaches Earth, providing the energy necessary for life to exist on our planet.
If the sun didn't exist, Earth would not have light or heat to support life as we know it. The absence of the sun would disrupt Earth's orbit and cause extreme cold temperatures, leading to the cessation of photosynthesis and eventual extinction of most forms of life.
The sun does release a lot of heat and radiation, but it doesn't "burn" the Earth because the Earth's distance from the sun is within a habitable range that allows for the right conditions for life to exist. The Earth's atmosphere and magnetic field also help protect it from the sun's most harmful effects.
Without the sun, all life on earth will cease to exist.
The Sun is essential for life on Earth because it provides energy for photosynthesis, which is the process plants use to produce oxygen and food. Without the Sun's energy, Earth would be too cold and dark to support life as we know it.
The sun is essential to life on this planet, so if the sun was not producing light/heat - life on this planet would no longer exist.
If the sun burned out all life on Earth would cease to exist. There would be no heat.
Life on Earth benefits from the fusion reactions occurring in the sun by providing the energy that sustains all living organisms through photosynthesis. The sun's fusion reactions also help regulate Earth's climate by providing warmth and driving weather patterns that are essential for maintaining a habitable environment.
The earth would freeze and life would cease to exist.
The world will be very dark and no life will exist on earth.
Plant earth is the third planet from the sun. This is partly why earth can sustain life. This keeps the temperature reasonable for life to exist.
Earth is just the right distance from the sun, receiving just enough energy to allow liquid water to exist on the planets surface. If earth were a little further away, then the water would be frozen as ice, while much closer and the water would boil away as water vapour. Liquid water is essential for allowing life to exist.
The Sun is the Earth's closest star. Without the Sun there would be no light and no heat and life would not be able to exist on Earth.
Because of the "Goldilocks Effect" -- Earth is situated far enough away from the Sun that water can exist in liquid form, but not so far that all of it is ice. Liquid water is an essential building block to life, so without it it is likely we would not be here.
The Earth is in the `habitable` zone, the right distance from the sun for life to exist in the form we are familiar with. This is because the temperature is just right for there to be liquid water on the planets surface - essential for life. If the Earth were too close, the water would boil off, too far and it would be permanently frozen.
