Answer:
The autumnal equinox occurs in September when the days start getting shorter and the nights are longer in the Northern Hemisphere
During a new moon phase, spring tides produce the greatest difference between high and low tides.
Tides are caused by gravity pulling the water of the oceans and causing it to bulge toward the large masses of the moon and sun.
During a lunar eclipse, the moon briefly passes through the penumbra, where it receives much less sunlight causing the moon to appear dim.
When the moon passes between the sun and the earth a/an solar eclipse occurs which momentarily blocks the sun's rays from reaching certain areas of the earth.
When the moon passes through the umbra, the earth's atmosphere refracts red light towards the moon.
