$\huge\colorbox{lavender}{Answer}$

So many questions

lemme answer ¯\_(ツ)_/¯

• Longitudes are known as meridians because in Geographical sense, meridians are great circles which are not parallel to each other but intersect each other at the North and the South Poles. ... All longitudes are great circles which meet at the Poles.

• 1. The length of the lines of latitudes decrease with distance from the equator. 2. All lines of latitude are circles parallel to the equator.

• the meridians are drawn vertically.
• the meridians are used to determine local time and to mark time zones.
• meridians are not parallel to each other. All meridians meet at the poles.
• every meridian is a semi circle.
• if drawn 1 degree apart, there would be 360 meridians.

• The North Temperate Zone extends between the Arctic Circle at 66° 33′ N and the Tropic of Cancer at 23° 27′ N. The South Temperate Zone extends between the Tropic of Capricorn at 23° 27′ S and the Antarctic Circle at 66° 33′ S.

• Torrid Zone is the hottest because it is very close to the equator. At this zone, the sun is very close to the earth and it receives the maximum heat from the sun.

• Polar regions have extremely cold temperatures. The regions are far away from the equator. They get less direct sunlight than other areas.

• The local time of a place is fixed according the movement of Sun in Sky based on which local time is calculated. Explanation: This time is differing from the standard time. Earth is rotating on its axis and get the sunlight in the various parts of the earth

• If watches are adjusted according to this time then it will be known as local time. But the highest position of the sun can be found only on a sunny day. Therefore it is correct to say that local time is the Sun-time.

• So, for 30 degrees, shift in time will be 30*4 = 120 minutes or 2 hours . For East direction, time is ahead of GMT. Therefore, local time of the given place is 2 pm.

• As the local TIMe differs by 4 minutes at every longitude, it would create a lot of confusion regarding time for any country as a whole which may stretch across several longitudes. Therefore each country selects a central meridian and the local time of this meridian is the standard time of that country.

• 24 time zones
• The world is divided into 24 time zones.

• London has a higher latitude ( close to the Arctic circle ) and it is in the temperate region , so it receives oblique rays of the sun making the temperature cooler .

• The International Date Line is an imaginary line that runs across the surface of the earth at 1800longitude. Since this longitude is diametrically opposite to that of the Greenwich Meridian, it results in a difference of 24 hours on crossing the line.

• If we had one single time zone for Earth, noon would be the middle of the day in some places, but it would be morning, evening, and the middle of the night in others. Since different parts of Earth enter and exit daylight at different times, we need different time zones.

• A circle of a sphere is a circle that lies on a sphere. Such a circle can be formed as the intersection of a sphere and a plane, or of two spheres. A circle on a sphere whose plane passes through the center of the sphere is called a great circle; otherwise it is a small circle.

don't forget to mark as brainest :) ☆thank u for question ☆

Answer 2

Answer:

I am telling answer 5

this is because all the places located on the same longitude have noon at the same time.
