Question

Consider the following statements:
(1) The Earth's rotation axis is not at ${90}^o$ to its orbital plane.
(2) The Earth's rotation axis is inclined at ${23.5}^0$.
Which of the statements given above is/are correct?

• A. Only 1
• B. Only 2
• C. Both 1 and 2
• D. Neither 1 nor 2

Answer 1

Answer: (C)

Both 1 and 2

Earth's rotation axis is inclined to its orbital axis at an angle of approximately 23.5 degrees and thus it is not perpendicular to its orbital plane. This axial tilt of the earth is the reason behind change of seasons on earth.
