Question

An equinox occurs when
(A)the north end of Earth’s axis is tilted away from the sun.
(B)the north end of Earth’s axis is tilted toward the sun.
(C) neither end of Earth’s axis is tilted toward or away from the sun.

Answer 1

Earth's tilt on its axis and constant motion in orbit cause the equinoxes and solstices.
At the equinox, the sun is directly above Earth's equator.

Answer 2

The correct answer is Option a.
An equinox is defined as an event that occurs when Sun's rays fall on the equator at noon and at an angle of 90°.

The axis of rotation of Earth must be perpendicular to the Sun's rays for this event to occur.

If the axis is titled to some angle even, then equinox will not occur.

Hence, the correct answer is Option a.

Answer 3

close this if you're done.
