What is the reason for the seasons?
The seasons are earth are caused by the tilt of 23.5 degrees off its access. This causes the angel of refraction to greater in the winter for the Northern hemisphere, so less heat is absorbed because the energy is spread over a greater area. The earth is actually closer to the sun in the winter for the Northern hemisphere.
What causes the lunar phases?
Lunar Phases are caused by the rotation of the moon around the sun and the sun light being reflected off the moon. At a new moon, the moon is between the sun and earth there for it can be seen from earth because it is over powered by the sun, and not reflecting any light onto the earth. at first and third quarter, it is to the side of the moon. Then at full moon the earth is between the moon and the sun.
