How is the weather on the earth formed?

The sun, the creator of the weather, has been burning in the center of the solar system for billions of years. Its core temperature reaches 27,000,000 degrees Fahrenheit (15,000,000 degrees Celsius). Numerous hydrogen nuclei collide and polymerize with each other to form helium nuclei and generate huge energy, most of which are released from the sun at the rate of 6× 10 27 calories per minute.

Of the total energy released by the sun, the earth only gets about 1/2, partly because the two stars are about 93,000,000 miles apart (65,438+050,000,000 kilometers) and partly because the surface area of the earth is relatively small. The rest of the energy disappeared in the universe. Although the energy reaching the earth is small, it is enough to heat the earth. It sustains the prosperity of life and provides energy for the atmosphere to form the weather as we know it.

The earth absorbs the solar spectrum of different wavelengths. Some are short-wave energy of visible light. Some are ultraviolet energy necessary for plants to grow through photosynthesis. Once this energy is absorbed, part of it will be reflected back to the atmosphere and into space by the surface and all objects on it. The ability to reflect solar energy is called reflectivity.
