Detailed explanation-1: -Photosphere-The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that.
Detailed explanation-2: -the Chromosphere (an irregular layer above the photosphere where the temperature rises from 6000°C to about 20, 000°C), a Transition Region (a thin and very irregular layer of the Sun’s atmosphere that separates the hot corona from the much cooler chromosphere), and the Corona (the Sun’s outer atmosphere.).
Detailed explanation-3: -The photosphere is the visible “surface” of the Sun.
Detailed explanation-4: -The photosphere is marked by bright, bubbling granules of plasma and darker, cooler sunspots, which emerge when the sun’s magnetic field breaks through the surface. Sunspots appear to move across the sun’s disk.
Detailed explanation-5: -The photosphere is known as the surface of the Sun because it is the physical layer we can see.
