Some words that describe the sun are hot, dense, spherical, huge, massive and layered. The sun also can be described as productive because it produces heat, light and radiation.
Heat is one of the defining characteristics of the sun. At its core, nuclear fusion results in temperatures of 27 million degrees Fahrenheit and higher. The sun is both the center of the solar system and the largest member of the solar system. The sun's diameter is 1,390,000 kilometers.
The sun is made up of several layers called the core, photosphere, chromosphere and corona. Solar winds originate in the corona and jut out into space.Learn More
The Stanford Solar Center states that sunspots form when the sun's magnetic field protrudes through its surface. The sun's magnetic field is composed of tubes that affect the sun’s surface temperature at the point of protrusion. Sunspots exhibit polarity, which creates a pair of positive and negative poles.Full Answer >
The sun holds the planets in their orbits, makes life possible on Earth and converts hydrogen into helium. The sun is a large ball of gas that is undergoing a thermonuclear reaction, which enables it to bathe the solar system in energy.Full Answer >
The sun's radiation interacts with Earth's atmosphere and lifeforms to act as the main source of energy. Solar radiation travels in straight waves. Earth's axis is usually angled to let this energy into its atmosphere so that it can reflect from the surface; if the sun's energy is unable to reach Earth because of its orbit, then ice ages occur.Full Answer >
Sunlight is the result of electromagnetic radiation being emitted from the sun. Ultraviolet, visible and infrared light are the result of this radiation, and they have a profound effect on the Earth.Full Answer >
