Decide whether each statement is true or false or choose the best answer to make each statement true.

1. ( true or false ) the number of hours of daylight, the rising and setting positions of the sun, and the altitude of the sun at noon are the same on both equinoxes.

2. there are approximately 12 hours of daylight and 12 hours of darkness everywhere on earth on ( the vernal equinox / the autumnal equinox / both equinoxes ). note: you may ignore the small effects discussed by the textbook authors on page 113 in the section titled, "clarifications about the real world."

3. ( true or false ) the sun rises due east and sets due west everywhere on earth on both equinoxes.

4. the equinoxes are the two points where the ( ecliptic / meridian / plane of the moon’s orbit ) crosses the ( galactic plane / zenith/nadir / celestial equator ).

As given below.

Explanation:

1. False,  as the number of daylight hours on the globe are mapped by the location f places over the various latitudes and altitudes. And the sun is not with the same both rise and set at both the hemispheres.

2. Yes, there exist changes of 12 hours in sunlight and darkness on earth due to the rotational speed of the earth on its axis as the earth is tilted 23.5 degrees so in both the hemisphere there exists equinoxes and solstices.

3. True, as the known fact the earth rotates in anticlockwise direction hence the eastern side gets to see the sun first and western side later this rule applies everywhere in the earth on both the equinoxes.

4. True, The celestial poles and equator are two points on earth that represent the equinoxes and the point that falls directly over the poles is called the zenith and the plane that touches is called the galactic plane.
