Sun gives us heat, light and energyadmin
Light from the Sun is the natural source of light that heats the Earth and makes life on Earth possible. Humans, animals & Plants all need sunlight to grow. Our life completely depends on the Sun or else there is a lifeless life without sun.
Sunlight is made of tiny units of radiant energy called photons. The Photons are born in the inferno of the Sun’s core. Each photon carries a speck of energy and trillions of photons hit each square meter of Earth every second. Together, they form sunlight. Clouds, water and ground, all reflect sunlight in the space and makes earth visible from a spaceship. The amount of energy that is carried by the wave of light or a photon largely determines the color of the light.
Light is an electromagnetic wave as it consists of both electric as well as magnetic fields. The electromagnetic radiations from sun exist in different wavelengths. The red wavelengths of the light are called long waves while violet wavelengths are called short waves. All the other colors lie between these long and short waves. Colors in the nature exist or are seen because of sunlight. Therefore the total world of beauty and aesthetics exist because of sunlight.Solar energy heats homes and greenhouses, produces wind power and generates water power through evaporation and rainfall.
Energy from the Sun sets the Earth’s weather in motion. Heat from the Sun causes water on the Earth’s surface to evaporate and form clouds that eventually provide fresh rainwater. Winds occur because the Sun’s rays are more direct and thus stronger at the equator than they are at poles. The strong rays in tropical regions warm the air there, causing it to rise. Cool air from the polar regions then flows under the warm tropical air. These movements create air currents that circulate around the Earth. These are influenced by the Earth’s rotation, the surface features of the continents and variations in the amount of moisture in the atmosphere.
