There is none, the world is on an angle in which the sun can only shine 24/7 on the tip of the earth towards Iceland area etc. but this is only during one of the seasons, i cannot remember what one but as the earth rotates around the sun the angle at which the sun is cast onto the earth changes. my best answer would be far far north on the top of earth

Nowhere on Earth do you have day or night continuously. Comments: At a particular place we don't have day and night at the same time. But it's always day somewhere and night somewhere, on Earth. At a particular place, day follows night and night follows day. The reason is that the Earth rotates. That means that the Sun appears to move across the sky, rising at the start of day and setting when the night is going to start.
the different seasons and the length of day and night varies from place to place

it is caused by if the earth rotates, if the earth goes away from the sun it is night . so that is how night is caused. Day is caused by the earth rotates and, the sunlight hits that place. so that is how the day is caused.
Light reaction take place in day time. Dark reaction take place at night
Any place on earth that lie on the equator will have equal day and night time.
Day or Night
For you, day occurs when the earth turns you in a direction where the sun can shine directly on you. Night occurs when the earth turns you in a direction where the sun can't shine on you, because part of the earth is in the way.For someone else in a different place, day and night may happen at different times from your day and night.
