Which of the following statements is true regarding earth movement ?
1. Earth rotates on its axis from west to east resulting into seasonal changes.
2. Earth revolution around sun results into occurrence of day and night on earth.
Answer: D
Both statements are false, so the answer is Both 1 and 2 are false.
Statement 1 has the effect wrong: the Earth does rotate on its axis from west to east, but rotation causes day and night. The seasons come from the Earth's revolution around the Sun with its axis tilted at about 23.5 degrees.
Statement 2 swaps the causes the other way: revolution around the Sun produces the seasons and the length of the year, not day and night. Since both statements give the wrong effect, 'Only 1', 'Only 2' and 'Both true' are ruled out.
