Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why does the Sun rotation vary with latitude?
A
Because it is composed of solids.
B
Because it is composed of liquids.
C
Because it is composed of gases.
D
None of the above
Explanation: 

Detailed explanation-1: -The rotation of the Sun varies with latitude because it is composed of gaseous plasma. The rate of rotation is observed to be fastest at the equator and decreases as latitude increases.

Detailed explanation-2: -The regions of the Sun near its equator rotate once every 25 days. The Sun’s rotation rate decreases with increasing latitude, so that its rotation rate is slowest near its poles. At its poles the Sun rotates once every 36 days! The interior of the Sun does not spin the same way as does its surface.

Detailed explanation-3: -Modern observations show that the speed of rotation of the Sun varies according to latitude, that is, it’s different as you go north or south of the Sun’s equator. The rotation period is about 25 days at the equator, 28 days at latitude 40°, and 36 days at latitude 80°.

Detailed explanation-4: -Unlike the Earth, the Sun is not a rigid body. As it’s a non rigid body, different parts of the Sun may rotate at different speeds, and they actually do so.

Detailed explanation-5: -Moving from the sun’s poles to its equator, the time in which this area of plasma rotates shortens. The poles complete a rotation in 35 days, while the area just above the equator completes a rotation in just 25 days. This means that no area of the sun completes an orbit anywhere near as rapidly as our planet does.
