The surface temperature of the sun is ?

(1) 6000 °C
(2) 12000 °C
(3) 18000 °C
(4) 24000 °C

Correct Answer : (1) The surface temperature of the sun is 6000 °C.

Explanation:

Our sun is 4.6 billion years old and it comprises 98 percent of hydrogen and helium.

The surface temperature of the sun is appx 6000 °C and it is 340 miles thick. This surface of the sun is also called the photosphere. The photosphere gives off the sun’s energy in forms of heat and light.

Sunspots on the photosphere are cooler and darker than the surrounding area. The temperature rises from the surface of the sun inwards towards the very hot center of the sun, where it reaches about 15,000,000°C.

It has dark spots called sunspots which are the only solar activity observable by the naked eye.

The uppermost layer of the solar atmosphere is called corona.

The surface temperature of the sun is 6000 Degree C and it is 340 miles thick. This surface of the sun is also called the photosphere.
