It's simply due to the Earth's spinning.
Areas near the equator have only about twelve hours of daylight, along with about 12 hours of night, each day.
Away from the equator this equal balance of daylight and night happens only around times called the "equinoxes".
No matter which way the poles tilt, the equator always receives enough direct sunlight to prevent a winter. Though, if there are no clouds to trap in the heat of the day, the equator can be very cold at night.
The equator does not pass through the Arctic Ocean.
The equator goes though South Africa, Africa and new Guinea
An equator
The equator passes through South America, Africa, and Asia.
Though you would expect twelve hours of day and twelve hours of night at the Equator, that is not the case. Because of atmospheric refraction and the size of the Sun, it actually exceeds 12 hours by about 7 minutes each day.
Snipes are wading birds with long bills. They are found in wetlands in Europe and Asia. In winter they migrate south towards the Equator. There is a North American snipe, though not the same species.
The Arctic Ocean
No, the number of hours in a day is constant and is determined by the rotational speed (or angular velocity) of the earth. Even though the equator has a larger diameter than somewhere near the poles, the angular velocity is the same for the entire earth.Please see the related link for an explanation in more detail.If your question is asking are the daylight hours for every day equal to 12 hours at the equator, then the answer is no. The Earth precesses as it moves through the sky, and hence the angle of the sun varies throughout the year. This is why you get the White Nights in some parts of northern Russia (i.e. daylight for all 24 hours) during some parts of the year.
Absolutely not. In the biological world, most processes strive towards equilibrium, though it hardly ever occurs.
Even though it is hot at lower altitudes at the equator, mountains are at a much higher altitude and thus can have ice on them.
The gravitational pull of the earth is pretty much the same anywhere between the poles and the equator creating a centripetal force pulling things in towards the earth.. However, the rotation of the planet results in an outward centrifugal force pushing things away from the earth. This force is greatest at the equator. Even though the gravitational pull is the same everywhere, the centrifugal force at the equator gives the impression of a very slightly lower gravitational pull.
