All questions of Globe: Latitudes and Longitudes for Class 6 Exam

The Frigid Zone lies near the Poles. The climate in the Polar Regions is very cold that is why the area is known as the Frigid Zone. It includes the area around the North Pole and the South Pole.

° E
b) 82° E
c) 90° E
d) 76° E

c) 90° E

Latitude is based on an imaginary line that circles Earth halfway between the north and south poles. This line is called the and it divides Earth into northern and southern hemispheres. A hemisphere is one half of a sphere. is a distance in degrees north or south of the equator, which is 0degree.

The Antarctic Circle is located at 66½° S latitude. It marks the region south of which there is at least one day per year when the sun does not rise and at least one day when it does not set.

The Tropic of Capricorn is located at 23½° S latitude. It is one of the five major circles of latitude that mark maps of the Earth and signifies the most southerly position at which the sun can be directly overhead.

Unlike latitude, the distance between degrees of longitude varies greatly depending upon your location on the planet. They are farthest apart at the equator and converge at the poles. A degree of longitude is widest at the equator with a distance of 69.172 miles (111.321 kilometers).

The Temperate Zones have moderate temperatures and experience distinct seasonal changes. They lie between the Tropic of Cancer and the Arctic Circle in the Northern Hemisphere and between the Tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere.

The Temperate Zone lies between the Arctic Circle and the Tropic of Cancer in the Northern Hemisphere. This zone experiences moderate temperatures and distinct seasonal changes.

This is why prime meridian is also known as the Greenwich Meridian. In a geographical coordinate system, the Greenwich Meridian (or prime meridian) is the 0 degree line of longitude from which we measure 180 degree to the west and 180 degree to the east. Most coordinate systems define a zero line at the equator that runs east-west.

Explanation:
When the sun is directly above the equator, it creates a line that divides the Earth into two equal parts. This is known as the equinox. During the equinox, the days and nights are equal throughout the globe.

Reasons:
This happens because of the following reasons:

1. Angle of Incidence: When the sun is directly above the equator, the angle of incidence of the sun's rays is perpendicular to the Earth's surface. This means that the sunlight is falling directly on the equator, creating equal amounts of daylight and darkness.

2. Earth's Rotation: The Earth rotates on its axis, which creates the cycle of day and night. During the equinox, the Earth's axis is perpendicular to the sun's rays, which means that the daylight and darkness are spread equally across the globe.

Other Options:
The other options in the question are incorrect because:

A) Poles: The poles experience periods of complete darkness and complete daylight, depending on the season.

C) Tropic of Cancer: The Tropic of Cancer is located at 23.5 degrees north of the equator. When the sun is directly above the Tropic of Cancer, it is the summer solstice in the northern hemisphere and the winter solstice in the southern hemisphere. This means that the daylight and darkness are not equal across the globe.

D) Tropic of Capricorn: The Tropic of Capricorn is located at 23.5 degrees south of the equator. When the sun is directly above the Tropic of Capricorn, it is the winter solstice in the northern hemisphere and the summer solstice in the southern hemisphere. This means that the daylight and darkness are not equal across the globe.
