An equinox occurs twice a year, when the tilt of the Earth's axis is inclined neither away from nor towards the Sun, the centre of the Sun being in the same plane as the Earth's equator.
The Torrid Zone is the hottest zone on the earth as it receives the vertical rays of the sun throughout the year, as the apparent movement of the sun is between the Tropics.
A globe is useful when we want to study the earth as a whole as we can see the water bodies, the axis, the tilt and the location of the countries on the globe.
The angular distance of the North Pole and South Pole from the equator is 90°So, the latitude of the North Pole is 90°N and that of South Pole is 90°S.
The equator is also said to be the $0^o$ latitude.
Answer
The Equator is called the $0^o$latitude as other lines of latitude are measured from the equator at $1^o$ in both north and south directions and parallel to each other.
Angular distance from the equator on both sides (North and South) is called latitude. Latitudes are 180° - 90° north of equator and 90° south of equator.
There is a needle fixed through the globe in a tilted manner which is called its axis. The imaginary line passing through the centre of the Earth and joining the two poles.
Why is it 5.30 p.m. in India and 12.00 noon in London?
Answer
The time difference between India and London is five and a half hours. India is located east of Greenwich at 82° 30’E. So, it will be 5.30 p.m. in India when it is 12.00 noon in London. The time difference between each degree of longitude is 4 minutes and since India is in the east, the time here will be ahead of Greenwich Time.
Why does the torrid zone receive the maximum amount of heat?
Answer
The mid-day sun directly faces the area between the Tropics of Cancer and Capricorn. So the heat received is maximum at these latitudes. These latitudes fall under the Torrid Zone.
What are parallels of latitude and meridians of longitude?
Answer
All parallels circles from the equator up to the poles are called parallels of Latitudes. Meridians of longitude are the lines of reference running from the North pole to the South pole.
A globe is an exact miniature model of the earth. It shows the earth in its actual shape, with all continents, oceans, etc marked at their proper places.
Why did some countries adopt more than one standard time?
Answer
Some countries have a great longitudinal extent and so they have adopted more than one standard time. For example, in Russia, there are as many as 11 standard times.
An imaginary line running on the globe divides it into two equal parts. This line is known as the equator. The northern half part from the equator is called the Northern Hemisphere and southern half called the Southern Hemisphere.
The area between the Tropic of Cancer (23 V20 N) and the Arctic Circle (66 V20 S) in the Northern Hemisphere and the Tropic of Capricorn (23 W S) and the Antarctic Circle (66V20 S) in the Southern Hemisphere have moderate temperatures. These are therefore, called Temperate Zones.
