Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which layer of the Sun is the most visible to an observer on Earth?
A
chromosphere
B
core
C
photosphere
D
corona
Explanation: 

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 photosphere is much brighter than the outer parts of the Sun’s atmosphere (the chromosphere and the corona), so regular photos of the Sun do not show the outer atmosphere.

Detailed explanation-3: -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-4: -The part of the Sun we see from Earth – the part we call the surface – is the photosphere. The Sun doesn’t actually have a solid surface because it’s a ball of plasma.
