The sun heats the Earth by shining light on it and radiating heat toward it. The atmosphere absorbs the heat, keeping it close to the Earth's surface where it can sustain life. Without heat and energy from the sun, life on Earth would not exist. Light energy not only warms the planet, it supplies the calories that are consumed by every living thing on the planet.Continue Reading
Several types of light shine on the Earth thanks to the sun, including infrared light, ultraviolet light and visible light. Because it is simple energy, light is transformed into heat once it reaches the surface of the Earth. This is why the temperature is warmer when the sun is shining.
In addition to light rays, the sun also emits radiation in the form of X-rays, microwaves and radio waves. When radiation reaches the atmosphere, the molecules of the atmosphere heat up, causing the molecules around them to become warm as well. The process that causes the atmosphere to warm up is called conduction, according to UCSB ScienceLine. Because there are no atmospheric particles for radiation to interact with in space, it remains quite cold even though the energy that warms the Earth passes right through it.Learn more about Our Sun
Heat energy from the sun reaches the Earth through a heat transfer process known as radiation. Radiation involves the transfer of heat through infrared waves.Full Answer >
Without the sun, all life on Earth except for deep sea microbes would die. Earth would cool to minus 100 degrees Fahrenheit within one year, plants would be unable to photosynthesize and gravity would no longer keep the Earth in orbit.Full Answer >
The sun is important to Earth because it warms the seas, generates weather patterns, stirs the atmosphere and provides energy to growing plants. The plants are responsible for providing oxygen and food for life to exist on Earth, according to the U.S. National Aeronautics and Space Administration.Full Answer >
Light is necessary for the survival of life on Earth, as almost all energy used by life is derived from the sun. Plants and algae use light energy in photosynthesis, which provides usable chemical energy for heterotrophic organisms. In addition, without light, the Earth would be completely cold and dark, as even the moon gets its glow from reflecting the sun.Full Answer >
