Does earth's tilt make day

Answer 1

No.
Earth's rotation makes day and night.
Earth's tilt affects the seasons and the ice ages.

You can demonstrate this with an orange and a flash light.

Stick a toothpick straight into the top and bottom of the orange.
This will help you rotate the orange.

Put a mark on the side of the orange about 1 inch down from the top.
This mark will represent you at about where North America or Europe is.
Not at the North Pole and not at the equator.

Shine the flash light at the side of the orange.

Now hold the top toothpick and rotate the orange.
Make sure the orange and the toothpicks are straight up and down.
As the mark (you) is in front of the flash light, that's day time.
As the mark (you) is behind the orange and away from the flash light, that's night time.

This time hold the top toothpick and lean the whole thing towards the flash light.
Make sure the orange and both toothpicks are leaning at an angle towards the flash light. Just lean it over about 1 inch, not too much.
This is the tilt of the earth.
Now when you rotate the orange, notice that the mark (you) stays in the light for more time than it stays in the dark.
This is why the days are longer in the summer.

Now hold the top toothpick and lean the orange away from the flash light.
This time when you rotate the orange notice that the mark (you) spends more time in the dark than it does in the light.
This is why the days are shorter in the winter.
