The moon, sun, earth, and tides

Moon phases

There are 8 different types of moon phases, but we are going to talk about waxing and waning moons. A waxing moon is when illumination increases and a waning? Well that's the opposite. There are four different types of waxing and waning moons. Waxing Crescent and gibbous, waning Crescent and gibbous. Also, there is the 1st and 3rd quarters, new moon and full moon.

Tides

Tides are when earth's water gets pulled by the moon and it makes bulges on the side of earth that is facing the moon, otherwise known as high and low tides. Diurnal is one high and low tide a day, semidiurnal is 2 high aand low tides a day. Spring tides occur when the sun, moon, and earth are in a straight line, and during a full moon or new moon. The sun and moon are working together. Neap tides occur when the sun and moon are perpendicular to each other and during quarter moons. They are working against each other.

Eclipses

There are two different types of eclipses: lunar and solar. A lunar eclipse is when the moon is in earth's shadow and a solar is when the earth is in the moon's shadow. A total eclipse is when the whole body of the sun or the moon is obscured from view. This is when that body is in the umbra shadow . A partial eclipse is when part of the sun or moon is obscured. This is when that body is in the prenumbra shadow.
