Glowing Surface of Sun is called?
VerifiedAnswer: photosphere
Explanation:
The photosphere is the visible glowing surface of the Sun that we see from Earth. Think of it as the Sun's outer shell that produces the bright light we observe during the day. The word "photosphere" comes from Greek words meaning "light sphere," which perfectly describes its function as the light-emitting layer of our star.
The photosphere has a temperature of approximately 5,500°C (9,900°F), which gives it that characteristic bright yellow-white glow. This layer is about 500 kilometers thick, which might sound like a lot, but it's actually quite thin compared to the Sun's total radius of about 696,000 kilometers. To put this in perspective, if the Sun were the size of a basketball, the photosphere would be thinner than a piece of paper!
What makes the photosphere special is that it's where most of the Sun's visible light is produced and released into space. Below this layer, the Sun's interior is so dense that light cannot escape directly. Above it lies the Sun's atmosphere, including the chromosphere and corona, but these layers are much fainter and usually invisible to the naked eye except during solar eclipses.
The photosphere isn't perfectly smooth - it has a granulated texture that looks like rice grains when viewed through powerful telescopes. These granules are actually convection cells where hot gas rises from below, cools at the surface, and then sinks back down. Each granule is about 1,000 kilometers across and lasts for about 10-20 minutes before being replaced by new ones.
