Question

The tail of the comet is formed near the orbit of Mars because:

• A. the head moves slower than the nucleus.
• B. the comet accelerates as it approaches the sun.
• C. solar radiations exert pressure on the head so as to form the tail.
• D. none of the above.

Answer 1

The correct option is C

solar radiations exert pressure on the head so as to form the tail.

Explanation for correct option:

1. Comets are made up of ice, dust, and rocky materials.
2. Comets revolve around the sun in a highly elongated orbit.
3. The tail of the comet appears when it reaches near the orbit of Mars.
4. It is formed because solar winds exert pressure on the head of the comet.
5. The tail of a comet extends up to 20-30 million kilometers.
6. Tail of the comet always points away from the Sun.

Hence option (C) is the right answer.
