Question

in regions near the north and south poles the sun does not set for several months in the summer. these areas such as the northern parts of alaska and norway are called land of the midnight sun because the sun remains visisble 24 hours a day. why is the sun visible for so many hours during the day

Answer 1

I think it has something to do with the equinox.Where the sun is is at the upper part of the hemisphere

Answer 2

Since the earth's rotational axis is tilted 23 degrees from the ecliptic (the path of the sun in our sky) for part of the year the northern hemisphere is tilted towards the sun and for part of the surface the sun doesn't set because it circles the sky always above the horizon.

Try this yourself.
Get an orange and paint an equator on it. Get a long skewer and stick it through the orange all the way through from the "north" to the "south" pole. Now get a flashlight about 2 feet from the orange and point it at the orange's equator. Now without moving the flashlight tilt the orange so one "pole" is about 20 degrees towards the flashlight. Without changing the flashlight or the orientation of the orange, move the whole orange/skewer thing in a circle around the flashlight and you will see that when the northern "hemisphere" is pointed at the flashlight part of the orange on the other side of the flashlight is lit up.
You gotta try this for yourself, and then you'll see what I mean.
Its actually pretty cool.

Answer 3

In Alaska during the longest day of the year (The sun never sets) they have a huge festival.

Because of the tilt of the earth at times the sun never sets in either the North or South pole. It's all about the angle the Earth, in relationship with the Sun.

Answer 4

This is easy. During summer the north pole is tilted towards the sun so even though the earth is spinning the north pole is relatively stationary with respect to the sun so the sun just "sits" just above the horizon all day long! In winter the opposite happens and it's dark all day long.

Answer 5

Earth tilts as it moves around the Sun. If the North Pole is tilted toward the Sun, it will be sunny all the time at the North Pole. The South Pole will be dark all the time because it is tilted away from the Sun.

Answer 6

Day and night are determined by the tilt and turn of the earth. When the part of the earth is tilted toward the sun, it is daytime, the part tilted away is nighttime. Since the poles stay tilted toward the sun for long periods of time, they have long days. They don't tilt towards the sun at the same time, but that's the basic idea.

Answer 7

The Earth is tilted 23.5 degrees, so the Sun always hits the top of the Earth and at times, the bottom when it is tilted the other way.

Answer 8

The Earth is tilited almost directly at the sun the whole time in the summer.In the winter,it is the opposite

Answer 9

Because of the way the earth is tilted.
