Answers
Answer:
1). Latitude is the angular distance of a place north or south of the Equator.
There are 180 parallels of latitudes apart from the Equator.
Each parallel of latitude is a circle.
2). The time of a place depends on the longitude that passes through it. Therefore, the standard time for each country is usually taken as the time of the central meridian that passes through it. ... Thus, we need a standard meridian for the country.
Indian Standard time (IST) is the time zone observed throughout India, with a time offset of UTC+05:30. India does not observe daylight saving time or other seasonal adjustments. In military and aviation time IST is designated E* ("Echo-Star"). It is indicated as Asia/Kolkata in the IANA time zone database.
3). The temperate zone is suitable for us to live because it has a moderate climate neither too hot nor too cold.
4). The earth has 360 imaginary lines called longitude or meridians running vertically between the poles. Each of this are called the degree. So the time difference between each longitude in 4 mins.
5). The Equator separates the Northern and Southern Hemispheres. The Equator is at 0° latitude. The Prime Meridian separates the Eastern and Western Hemispheres. The Prime Meridian runs through Greenwich, England and is at 0° longitude.
