Seasons and the shape of the moon

Seasons are caused from the position and orbit rotation of the earth from the sun. Your weather of the particular region you live will depend on the axis you are closest to.

However the truth is distance from the sun is not related to how hot or cold the weather is.

The moon has different shapes because the light from the sun casts a shadow from earth. The shape depends on where the earth and sun are during orbit.

We showed where the moon is (time matters) in the classroom effects it's shape.

I'm not sure how correct all this is.

  1. You need to be more clear with your answers, these seem incomplete.

    As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can. Midway between these two times, in spring and autumn, the spin axis of the earth points 90 degrees away from the sun. This means that on this date, day and night have about the same length: 12 hours each, more or less.

  2. You should also redo your explanation for the lunar cycle
