The masssive movement
the movement of the sun, moon and earth really has a huge impact on earth. when the tilted earth rotates which takes 23+hours, half of the earth gets sun light (day) and half gets no light (night) when moon moves which is also known as the phases of the moon the gravity controls the oceans water level. it can be high, normal or low. waxing is when moon goes from being small to big and waning is when the moon goes from big to small, new moon is when the moon is invisible to sun,quater moon is when Half of the moon is missing and gibbous is when more then half of the moon shows. the sun light also as causes the seasons. the part which gets direct sun light has summer or spring, and where it gets indirect light its winter or fall. equator has no season because its in the middle.
