PLSS..... ANS ME..... IT'S VERY IMPORTANT......PLS​

Answer 1

Answer:

here is your answer .

hope it's helpful for you.....

Explanation:

Latitude is the angular distance of a point on the earth’s surface, measured in degrees from the center of the earth.

As the earth is slightly flattened at the poles, the linear distance of a degree of latitude at the pole is a little longer than that at the equator.

For example at the equator (0°) it is 68.704 miles, at 45° it is 69.054 miles and at the poles it is 69.407 miles. The average is taken as 69 miles (111km).

1 mile = 1.607 km.

Important parallels of latitudes

Besides the equator (0°), the north pole (90°N) and the south pole (90° S), there are four important parallels of latitudes–

Tropic of Cancer (23½° N) in the northern hemisphere.

Tropic of Capricorn (23½° S) in the southern hemisphere.

Arctic circle at 66½° north of the equator.

Antarctic circle at 66½° south of the equator.

latitudinal heat zone on earth

The mid-day sun is exactly overhead at least once a year on all latitudes in between the Tropic of Cancer and the Tropic of Capricorn. This area, therefore, receives the maximum heat and is called the torrid zone.

The mid-day sun never shines overhead on any latitude beyond the Tropic of Cancer and the Tropic of Capricorn. The angle of the sun’s rays goes on decreasing towards the poles. As such, the areas bounded by the Tropic of Cancer and the Arctic circle in the northern hemisphere, and the Tropic of Capricorn and the Antarctic circle in the southern hemisphere, have moderate temperatures. These are, therefore, called temperate zones.

Areas lying between the Arctic circle and the north pole in the northern hemisphere and the Antarctic circle and the south pole in the southern hemisphere, are very cold. It is because here the sun does not raise much above the horizon. Therefore, its rays are always slanting. These are, therefore, called frigid zones
