SEASONS AND DAY&NIGHT
We get the seasons because of the earths position around the sun, so in summer the earth is directly facing the sun, more sunlight hits the earth causing it to be warmer and we get more sun.During Winter the earth is facing away from the sun which causes less sun rays to hit the earth but we still get sunlight. We get Day and Night from the way the earth rotates. It takes 24 hours for the earth to fully rotate, so during day time we're facing the sun and at night were facing away from it.
Orbit and rotation of sun
The sun is in the center of the universe and is the largest star and planet in the universe. It rotates every 25-36 earth days. The sun doesn't orbit any other planet, but all planets orbit around the sun.
Rotation and orbit of the earth
The earth rotates on its own axis, which is 23.5 degress and takes 24 hours to complete a full rotation and 365 1/4 days to complete a full revolution around the sun. The Earths tilt/axis is the reason why we have the change of seasons and climate change. The earths orbit revolves around the sun. The reason we have leap years is beacause each year we have 365 1/4 days and after 4 years it adds up to 1 extra day, which is february the 29th, whilst normally we only have 28 days in february.
orbit and rotation of the moon
The Moon orbits the earth, creating phases. Phases happen every month where the moon is a different shape, from what we can see from earth. There are 8 phases, and between the new moon and full moon they're waning and between the full moon to new moon they're waxing.
