The Prime Meridian, a zero-degree longitude, divides the Earth into two equal halves—the Eastern Hemisphere and the Western Hemisphere—which contain 180 meridians each. All these meridians are equal in length and run from the North Pole to the South Pole.
What is the prime meridian short answer?
The prime meridian is the line of 0 longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. Any line of longitude (a meridian) can serve as the 0 longitude line.
What is the prime meridian Class 5?
The prime meridian is the imaginary line that divides Earth into two equal parts: the Eastern Hemisphere and the Western Hemisphere. The prime meridian is also used as the basis for the world’s time zones. The prime meridian appears on maps and globes. It is the starting point for the measuring system called longitude.
Why is prime meridian called so?
We measure these coordinates as lines of latitude and longitude. The 0° line of longitude starts at the Prime Meridian. It’s also called the Greenwich Meridian because it runs through Greenwich, England.
What is meridian answer?
A meridian is an imaginary line from the North Pole to the South Pole. Meridians are drawn on maps to help you describe the position of a place.
What are latitudes for Class 6?
Answer: One of the imaginary circles parallel to the Equator is called latitude.
What is Prime Meridian of India?
82°30’E which is the Standard Meridian of India passes through Mirzapur (Uttar Pradesh). The time of this meridian is taken as the standard time for the whole country. Was this answer helpful?
What is a globe Class 4?
A globe is a spherical model of Earth. It serves purposes that are similar to some maps. A model globe of Earth is known as a terrestrial globe. A model globe of the celestial sphere is called a celestial globe.
What is longitude Class 9?
In geography, longitude refers to the imaginary lines that bisect the globe through the North and South Poles (the ones that run vertically, as opposed to the lines of latitude that run horizontally, parallel to the equator).
What is grid in geography class 6?
Explanation: The network of longitudes and latitudes intersecting each other to form a web is known as a grid.
Why GMT is used?
Greenwich Mean Time (GMT) has been used to clearly designate epoch by avoiding confusing references to local time systems (zones). Historically, astronomers used Greenwich Mean Astronomical Time (GMAT), in which the astronomical day began at noon at longitude (0°), in accord with scientific tradition.
Is Prime Meridian A great circle?
All the meridians on Earth are great circles. Meridians, including the prime meridian, are the north-south lines we use to help describe exactly where we are on the Earth. All these lines of longitude meet at the poles, cutting the Earth neatly in half. The Equator is another of the Earth’s great circles.
What is other name of Prime Meridian?
Sometimes called the Greenwich Meridian or the International Meridian, Earth’s prime meridian crosses the original site of the Royal Observatory in Greenwich, England. It is the circular line by which other longitudinal lines, or meridians, are referenced — otherwise it wouldn’t be prime.
What is a globe class 6?
a. A globe is a spherical figure which is a miniature form of earth. It gives us a three-dimensional view of the whole Earth by showing distances, directions, areas, etc.
What are latitudes Class 5?
The imaginary lines that run from East to West are called Parallels or Lines of Latitude. The imaginary lines that run North to South from the poles are called Meridians or the lines of Longitude. Lines of Latitude are east-west circles around the globe.
Why do we have 6th class time?
Answer: We need a standard meridian for India because of the vast longitudinal extent of the mainland. Thus, there is a time lag of two hours from Gujarat to Arunachal Pradesh. Hence, time along the Standard Meridian of India passing through Mirzapur is taken as the Standard time for the whole country.
What is an equator Class 6?
Equator is an imaginary line running on the globe that divides it into two equal parts. The northern half of the earth is known as the Northern Hemisphere and Southern half is known as the Southern Hemisphere.
What is a leap year class 6?
(c) Every fourth year, February has 29 days instead of 28 days. Such a year with 366 days is called a leap year.
What is an axis Class 6?
Axis is an imaginary line that extends from the North pole to the South pole. The Earth rotates on its axis.
Where is the prime meridian?
The prime meridian is the line drawn north to south at 0° (0 degrees) longitude. Sentences: The prime meridian divides Earth into the Eastern Hemisphere and the Western Hemisphere. The prime meridian is at 0° (0 degrees) longitude.
What is the standard meridian of India Class 6?
82°30’E.
Hint – The Standard Meridian of India is located at 82°30’E. The time along this latitude is taken as the official time across the country.
