Why do places on earth experience 24 hours of sunlight?

The earth is on an axis and is slightly titled to one side, a bit like the sign in brackets ( / ), so when the top end is facing the sun, the north pole has 6 months of daylight whilst the south has 6 months of darkness.... why?Well as you probably know it takes 12 months (1 year) for the earth to get around the Sun, so because the earth is tilted, the north pole will face the sun for half of the time it takes to get around the sun (6 months) and then it would be the bottom end, the south pole facing the sun.

So people who live around the equator, will always receive around about 12 hours daylight and 12 hours darkness all year around. Whilst people living between the equator and north pole will have longer days with sunlight whilst the north pole is facing the sun (summer) and shorter days with daylight whilst the south pole is facing the sun (winter). Yet for people living between equator and south pole it is reversed, that's why when its summer in the UK or USA its winter down in Australia and vice versa. i hope this has answered your question! :)
