Both false
Answer:
Ans 4 - The change in seasons is caused by the rotational tilt of the earth on its axis when it revolves around the sun. The earth has a tilt of 23.50 on its elliptical plane and when the tilt moves towards or away from the sun, when the earth is revolving around the sun, it causes change in seasons.
Ans 5 - I think its True
Marking the beginning of spring, the sun will cross the plane of the earth's equator on Monday morning, making day and night of approximately the same duration. The event, known as equinox, is eagerly awaited by space enthusiasts as it takes place only twice a year, on March 21 and September 23.
