Q. Consider the following statements:
1.The Sun rotates about its axis like the Earth.
2.The Sun has a rotation period of one day.
3.Plasma is the highly ionized state of matter that makes up the Sun.
Which of the statements given above are correct?
Answer: C
Notes:
Explanations –
Statements 1 and 3 are correct. The Sun, like the Earth, rotates about its own axis. However, the Sun’s rotation is more complex because it is made of plasma (a hot, ionized gas), and different parts of the Sun rotate at different speeds. This is known as differential rotation. For example, the Sun’s equator rotates faster (about 25 days) than its poles (about 35 days).
Statement 2 is incorrect. The Sun’s rotation period is much longer than one day. At the equator, it takes about 25 days to complete one full rotation, and at the poles, it takes about 35 days.
