question 3: which of the following is not caused by the moon

b. moonrise
c. sunrise
d. tides

The correct answers are:

1. C. during a new Moon;

The spring tides occur twice a month, after new Moon, and after full Moon. They cause the biggest differences in the high and low tides, with the high tides being abnormally high, and the low tides being abnormally low.

2. C. perigee;

The perigee is the point at which the Moon is closest to the Earth. This happens because the Earth is not right in the middle of the Moon's revolution, thus making one part of it being closer, and other part being further away.

3. C. sunrise;

The Moon has no influence on the sunrise whatsoever. The sunrise depends only on the movement of the Earth in comparison to the Sun, with the part is the becoming exposed to it as the Earth rotates being the part that is experiencing the sunrise.
