If the sun shines equally in almost all areas, why are regions around the equator hotter than areas around the poles? It is all about the tilt of the Earth’s axis. The Amount of Sunshine Received at the Equator Thankfully, we still have a few billion years before this happens. (1) The Sun shines because it is hot. The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). This swirling gas may be the result of intense magnetic fields and may explain why the Sun's corona is so hot. The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius). The distance from Earth to Sun is 150 million kilometers (km), which equals 1 astronomical unit (AU), which equals 8.3 light minutes (that is, the distance traveled by light in 8.3 minutes). Dave - The Sun is incredibly hot, but the Sun is not throughout the whole of space. Below is an explanation of why equatorial regions are very hot, including direct vs indirect sunshine, the reflection of sunrays, and atmospheric differences. Arizona is Close to the Equator and has Higher Elevation. It doesn't make any sense! During the summer, the sun’s rays hit the Earth at … "Why the Sun's corona is so hot is a long-standing puzzle. The sun is hot The sun is so hot that everything on it is a gas Copper, iron, aluminum And the surface of the sun are all gas The sun is large If the sun is so large a million earths could fit inside And yet the sun's just a middle-sized star The sun is far away It's about ninety three million miles away And that's why it looks so small The fact that the Sun is hot should not be news to a single person. It’s about 2,300 miles from the equator, which is close enough to mean it receives a lot of the sun’s energy, especially at the end of the year. The Sun is, by far, the nearest star to Earth. In fact, the Earth is farthest from the sun in July and is closest to the sun in January! Ultraviolet light comes from the sun, but it can also bounce off of other surfaces like water, snow, and concrete. Solar astronomers think that the key lies in the magnetic field, … Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. So, when you're sitting in space, in the Earth’s orbit, you're getting hit by about the same amount of sun that you get if you're sitting on Earth, but the rest of you can see deep dark space which is about -270 degrees centigrade. Five different wavelengths of light reveal a vortex of gas in the Sun's atmosphere. If you ask a child to paint a picture of the sun, you will most likely get a bright yellow circle on a piece of paper. Eventually, the sun will become so big and hot that Earth will be scorched, making it uninhabitable. ... Sunblock contains chemicals that can reflect or absorb the ultraviolet light, leaving your skin sunburn free. After about 1-to-2 billion years, the Sun will be burning hot enough that Earth's oceans will boil away entirely, making liquid water impossible on the surface of our planet. It's as if a flame were coming out of an ice cube,” said team lead Dr. David H. Brooks of George Mason University. The Sun’s surface is about 10,000 degrees Fahrenheit, which seems toasty enough.
