What are meridians of longitude?

What are meridians of longitude?

Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arcdegree of longitude. The distance around the Earth measures 360 degrees.

What are the three features of Meridian?

All meridians are of the same length and each one is a semi-circle. If any two opposite meridians are taken together, they form a complete circle, which is a great circle. The distance between any two meridians is maximum at the Equator, which is about 11 km for one degree of longitude.

What are the important meridians of longitude?

The most important line of longitude is the Prime Meridian (0 degrees) which passes through Greenwich, England. All other lines of longitude are located east or west of this line. Longitude and Time: The Prime Meridian separates east and west in the same way the equator separates north and south.

How many meridians of longitude are there?

360 degrees

Why there is no higher latitude than 90 degree north and 90 degrees south?

Latitude is the angular distance from the plane of the Equator. Latitude only has to cover 180 degrees, from the North Pole to the South Pole. All circles make a maximum angle of 900 from the plane of the Equator. Therefore the maximum, latitude is 900 N in the Northern hemisphere and 900 S in the Southern Hemisphere.

Why can we go 180 degrees east and west but only 90 degrees north and south?

“Longitude” goes 360 degrees, 180 East to 180 West, to cover the entire 360 degrees around the equator. So latitude only has to cover 180 degrees, from the north pole to the south pole. Taking the equator to be 0 degrees, the north pole is 180/2= 90 degrees N, the south pole is 180/2= 90 degrees S.

Which is the longest and smallest longitude?

The radius of each longitude decreases from equator to the pole. The longest latitude is 0° latitude(equator) and the shortest is 90° latitude (both of the poles).

Which is the longest Meridian?

prime meridian
