How many hours of sunlight occur at the equator as opposed to the poles?

The answer is that at the equator, the daily hours of sunlight are almost exactly 12 hours, while at the poles, a day includes either 24 hours of sunlight or 24 hours of night (ignoring the effect of cloud cover).
However, all parts of the Earth's surface will receive approximately the same amount of sunlight annually, that is, the time when the Sun is above the horizon. The difference is in the timing, with some areas receiving longer days for one half of the year, while the other half receives shorter days. These are the summer and winter seasons.
In the Earth's equatorial region, between the Tropic of Cancer (about 23.5°N) and the Tropic of Capricorn (about 23.5°S), days and nights are always about the same, 12 hours each, with some periods of twilight before dawn and after sunset. The actual day is very slightly longer than 12 hours.
At the higher latitudes, nearing the poles, the period of sunlight begins to reach the other extreme, with sunlight for 24 hours for at least some days in the year, and 24 hours of night or twilight in the opposite season. The poles themselves experience 6 months of continuous day, with the Sun circling the horizon, followed by 6 months of twilight or night, when the Sun never rises (it may provide twilight conditions for several weeks).

Where do hurricanes occur on the equator?
No, Hurricanes occur in the tropics, but at the equator there is not enough Coriolis force to start them turning.
Why does photosynthesis occur in leaves?
Photosynthesis needs sunlight to occur. Therefore photosynthesis does not occur in the roots because they do not receive any sunlight. The leaves are the parts of the plant most exposed to the light.
Where does earth's greatest speed of rotation occur?
At the equator
What happens if the ozone layer is extinguished?
we will all die unless the scientists invent something like a heat proof suits. The issue though is completely impossible as long as we have sunlight and oxugen. Sunlight reacts with oxygen to create ozone. This is why we only see thinning occur during the winter months at each pole and no thinning near the equator where sunlight is consistant.
What thing have to happen for photosynthesis to occur?
What is needed to occur is Water, Carbon Dioxide, chorophyll, sunlight for the Photosynthesis to occur.
Do seasons occur at all the latitudes?
The closer you get to the equator, the less seasonal variation you see, since the equator gets slightly more than twelve hours of sunlight every day of the year.
Where do swamps occur?
They usually occur in desert or places on the equator.
Why do most earthquakes occur in the north-east of the equator?
Why did you specify northeast of the equator
Where do hurricanes occur on the equator?
No, Hurricanes occur in the tropics, but at the equator there is not enough Coriolis force to start them turning.
How do the days and nights occur?
Days and nights occur because of the diurnal rotation of the earth. The sun stays still, and the earth spins once a day, so for 12 hours half the earth is in sunlight.
Why does photosynthesis occur in leaves?
Photosynthesis needs sunlight to occur. Therefore photosynthesis does not occur in the roots because they do not receive any sunlight. The leaves are the parts of the plant most exposed to the light.
Where does cold temperature occur?
In places away from the equator
Where does earth's greatest speed of rotation occur?
At the equator

What energy is need for photosynthesis to occur?
Sunlight
What countries on the equator are mostly desert?
There are no countries on the equator that are mostly desert. Because the region of the equator is noted for its heavy rainfall, deserts do not occur there.
What thing have to happen for photosynthesis to occur?
What is needed to occur is Water, Carbon Dioxide, chorophyll, sunlight for the Photosynthesis to occur.
