# How the duration of sunlight changes from the equator to the poles with respect to the angle of incidence during the solstice?

## How the duration of sunlight changes from the equator to the poles with respect to the angle of incidence during the solstice?

Answer: The sunlight falls directly on the equator, but as it moves from equator towards poles the angle of incidence increases and it becomes inclined at the poles. This where the lines of the latitude divide the Earth into three heat zones namely the Torrid zone. Here the sun rays are vertical.

### What is the length of daylight at the North Pole?

24 hours
› “The North Pole has sunlight 24 hours a day now and will until early autumn.

#### Why does the length of the day become longer as you move north of the equator?

The Sun is directly over the Equator and the days and nights are equal length everywhere. As time passes the Sun’s position moves North and more of the Northern hemisphere is in direct sunlight. The days get longer.

How do the amount of daylight hours change as you move from the equator to the North Pole during summer?

The Earth’s movement around this axis causes the change between day and night. During summer in the Northern Hemisphere, daylight hours increase the farther north you go. The Arctic gets very little darkness at night. The seasonal changes in daylight hours are small near the Equator and more extreme close to the poles.

Why do the North Pole and South Pole have six months of day and six months of night?

The earth is tilted on its axis, because of which very poor sunlight is allowed to reach the north and south poles. When the north pole is tilted towards the sun,it experiences continuous day light for six months. And when the pole is tilted on the other side, it experiences continuous night for six months.

## Why the rotation of the Earth gives us the sense of time?

Answer: Our clock time is based on the earth’s rotation with respect to the sun from solar noon to solar noon. This is a solar day, and it is divided into 24 hours. Because Earth travels about 1 / 365 of the way around the sun during one day, there is a small difference between solar time and sidereal time.

### Do the days get longer and shorter at the equator?

How does the length of day and night vary at the equator throughout the year? Daylight at the equator is always a bit longer than darkness, the result of the refraction of light through the atmosphere that allows us to see the sun a few minutes before it rises and a few minutes after it sets.

#### When do daylight hours change in the northern hemisphere?

During summer in the Northern Hemisphere, daylight hours increase the farther north you go. The Arctic gets very little darkness at night. The seasonal changes in daylight hours are small near the Equator and more extreme close to the poles.

Is the length of the day longer at the equator?

In the Northern Hemisphere, the length of the day is longer during the months when the North Pole is tilted towards the Sun and shorter during the months when it’s tilted away from the Sun. The reverse is true for the Southern Hemisphere. The Equator is exactly halfway in between the poles.

When do daylight hours change in the Arctic?

The Arctic gets very little darkness at night. The seasonal changes in daylight hours are small near the Equator and more extreme close to the poles. There are four events that mark the passing stages of the sun, equinoxes and solstices. The two solstices happen June 20 or 21 and December 21 or 22.

## Is the sun always up for exactly 12 hours at the equator?

It is always exactly 12 hours. In the Northern Hemisphere, the length of the day is longer during the months when the North Pole is tilted towards the Sun and shorter during the months when it’s tilted away from the Sun. The reverse is true for the Southern Hemisphere.
