what do we get from the sun?

 There's good reason why vitamin D is called “the sunshine vitamin.” When your skin is exposed to sunlight, it makes vitamin D from cholesterol. The sun's ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for vitamin D synthesis to occur.

The Sun is a very large light source, its diameter exceeding that of both the Earth and the Moon. This means that, on their journey through space, both objects produce all 3 types of shadows.

The Sun emits EM radiation across most of the electromagnetic spectrum. ... The Sun also emits X-rays, ultraviolet, visible light, infrared, and even radio waves; the only direct signature of the nuclear process is the emission of neutrinos.

The atmosphere is heated by radiant energy from the Sun -‐ solar energy. Lots of different kinds of rays are sent out by the Sun, but the most important ones are visible light and invisible light called infrared radiation. ... Visible light is absorbed by Earth's surface. The land and seas warm up.

Some of this energy is transferred to the atmosphere by conduction and convection . The Earth also radiates lower frequency infrared radiation. Some of this infrared radiation is transmitted through the atmosphere back out into space, and some is absorbed by greenhouse gases in the atmosphere.

All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.

About 73% of the Sun's mass is hydrogen, and another 25% is helium. All the other chemical elements (including those we know and love in our own bodies, such as carbon, oxygen, and nitrogen) make up only 2% of our star. The 10 most abundant gases in the Sun's visible surface layer are listed in Table 1.

The Short Answer: Our Sun is a bright, hot ball of hydrogen and helium at the center of our solar system. It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth.

Greenhouse effect. Step 1: Solar radiation reaches the Earth's atmosphere - some of this is reflected back into space. Step 2: The rest of the sun's energy is absorbed by the land and the oceans, heating the Earth. Step 3: Heat radiates from Earth towards space.

This sounds like a strange question, but think about it. Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.

Great questions! The sun helps plants grow by providing energy for the process of photosynthesis to occur. Photosynthesis is the way plants convert inorganic resources, such as sunlight, water, carbon dioxide, and minerals, into organic resources that the plant can use. The sun helps humans in several ways!

Winds. Sunlight hits the Earth most directly at and near the equator. The extra solar energy absorbed there heats up the air, land and water. ... Add in effects of the Earth's rotation and you get trade winds -- the constant flow of air across the Earth's surface.

The Sun emits energy at all bands in the Electromagnetic Spectrum, but emits most strongly at visible, UV and Infrared frequencies. Our atmosphere stops 98% of all UV rays from the Sun and the remaining UV rays are used by our bodies to help produce Vitamin D.

Of the 340 watts per square meter of solar energy that falls on the Earth, 29% is reflected back into space, primarily by clouds, but also by other bright surfaces and the atmosphere itself. About 23% of incoming energy is absorbed in the atmosphere by atmospheric gases, dust, and other particles.

The Sun emits radiation right across the electromagnetic spectrum, from extremely high-energy X-rays to ultra-long-wavelength radio waves, and everything in-between. The peak of this emission occurs in the visible portion of the spectrum.
