Moon

There are 8 phases in the moon. There is anew moon which the sun is facing the back of the moon. There are 2 kinds of crescents a waning which is always on the left side of the sun and then there is a waxing which is always on the right they also just show a sliver of the moon. There is also 2 types of gibbous moon the waning and the waxing they show more than half of there moon. 1st and 3rd quarter is when the moon is showing half. The 1st quarter is on the right and 3rd quarter is on the left. The full moon is when all of the moon is showing then it repeats the whole thing over again.

Eclipses

A solar eclipse casts a shadow and when the earth is in the penumbra and umbra or the sun's shadow."Then the portion of the earth has an eclipse of the sun." In the shadow of the umbra you have a view of the total eclipse but if you are in the penumbra you can only see part of the solar eclipse when there can only be a new moon in a solar eclipse. A lunar eclipse occurs when there is a full moon. Earth casts a shadow that the moon comes into then the same thing happens with a lunar eclipse when they go into an umbra and a penumbra.

Seasons

Seasons occur when the earth is moving on it's axis by 23.5 degrees. That means the sun would strike the parts of earth at different times.which means if the northern hemisphere was summer at this time it that would mean that it would be winter on the opposite side of the northern hemisphere.

Tides

There are two different types of tides a Neap Tide and a Spring Tide. A Spring Tide is when the two types are a full and new moon. A Neap Tide is when the third and first quarter moon. The moon and sun make the tides the moon is closer to the earth so the moon has a more affect on the tides. A Neap Tide has a 90 degree angle and a Spring Tide has an 180 degrees angle.
