What’s another name for lines of longitude?

What’s another name for lines of longitude? Lines of longitude are also known as meridians.

Lines of longitude and latitude create a grid pattern on the globe for navigation. The Earth is split into 360 lines of longitude. The Prime Meridian runs through Greenwich, England, while the equator serves as the zeroth pace for latitude.

What is latitude with diagram?

Lines of latitude measure north-south position between the poles. The equator is defined as 0 degrees, the North Pole is 90 degrees north, and the South Pole is 90 degrees south. Lines of latitude are all parallel to each other, thus they are often referred to as parallels.

What are the 5 major lines of longitude?

The five major parallels of latitudes from north to south are called: Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and the Antarctic Circle. Five major parallels of latitudes.

What do we call each half of Earth?

Powered by. Any circle drawn around the Earth divides it into two equal halves called hemispheres. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western. … The Earth can also be divided into hemispheres along meridians, or lines of longitude.

Why is 180 W and 180 e the same line?

The 180th meridian or antimeridian is the meridian 180° both east and west of the Prime Meridian, with which it forms a great circle dividing the earth into the Western and Eastern Hemispheres. It is common to both east longitude and west longitude.


How many latitudes are there in total?

Lines of latitude are called parallels and in total there are 180 degrees of latitude. The distance between each degree of latitude is about 69 miles (110 kilometers).

Which is the longest latitude?

The Equator is the longest circle of latitude and is the only circle of latitude which also is a great circle.

Is latitude vertical or horizontal?

Hemisphere – one half of the planet Page 2 Latitude – horizontal lines on a map that run east and west. They measure north and south of the equator. Longitude – the vertical lines on a map that run north and south. They measure east and west of the Prime Meridian.

What are the 7 major lines of longitude?


The 7 major lines of latitude are:

  • North Pole.
  • Arctic Circle.
  • Tropic of Cancer.
  • Equator.
  • Tropic of Capricorn.
  • Antarctic circle.
  • South Pole.

What are the 2 major longitudes?

Some Important Longitudes include:

1. Prime Meridian = Longitude 0o (Greenwich Meridian). 2. International Date Line (Longitude 180o).

What are the two main longitude lines?

Meridians (lines running from pole to pole) connect points with the same longitude. The prime meridian, which passes near the Royal Observatory, Greenwich, England, is defined as 0° longitude by convention. Positive longitudes are east of the prime meridian, and negative ones are west.

Is Earth a perfect sphere?

Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.

What are the 7 continents and their hemispheres?


The Earth is divided into seven continents: Africa, Antarctica, Asia, Australia, Europe, North America and South America.

  • Africa. ••• Africa is mostly in the Eastern Hemisphere and is almost entirely surrounded by water. …
  • Antarctica. ••• …
  • Asia. ••• …
  • Australia. ••• …

  • South America. •••

Which country is in all four hemispheres?

Once combined, the 33 stunning, paradisiac islands and atolls make Kiribati the only country in the world to cross all four hemispheres.

Is 180 a valid longitude?

Overview. The valid range of latitude in degrees is -90 and +90 for the southern and northern hemisphere, respectively. Longitude is in the range -180 and +180 specifying coordinates west and east of the Prime Meridian, respectively.

Is 180 East and 180 West the same?

Basically, 180 east and west are the same. In other words, [45,180] is the exact same location as [45,180].

What is another name for 180 degrees longitude?

The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at 180 degrees. It is the basis for the International Date Line.

Why is North Pole 90 degree?

It is the precise point of the intersection of the Earth’s axis and the Earth’s surface. From the North Pole, all directions are south. Its latitude is 90 degrees north, and all lines of longitude meet there (as well as at the South Pole, on the opposite end of the Earth).

Why there are 180 latitudes and 360 longitudes?

Latitude lines are comprehensive circles, with the middle at 0° and the pole at 90°. The South Pole and the North Pole have separated by 180° apart, The longitude lines cross from the North Pole to the South Pole. … This is why it begins at zero and finishes at 360 longitudes.

What lines are called meridians?

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 is the most famous line of longitude?

The most famous line of longitude is the prime meridian which passes through Greenwich, England. The prime meridian is at 0 degrees longitude. There are 180 degrees of longitude to the east (right) and 180 degrees of longitude to the west (left) of the prime meridian.

Which is the shortest latitude?

Arctic Circle (66°33′48.3″ N) Tropic of Cancer (23°26′11.7″ N) Equator (0° latitude) is the shortest latitude.

Which is the longest line in the Globe?

Answer: The longest is the equator, whose latitude is zero, while at the poles, at latitudes 90° north and 90° south (or –90°), the circles shrink to a point. Both longitudes or meridians, interconnecting the north pole and the south pole, are equivalent lines of similar length.

Is latitude up or sideways?

Have students look at the U.S. map and find the lines running across and up and down the page. Tell students that the lines running across the page are lines of latitude, and the lines running up and down the page are lines of longitude. Latitude runs 0–90° north and south. Longitude runs 0–180° east and west.

Is latitude first or second?

Handy tip: when giving a co-ordinate, latitude (north or south) always precedes longitude (east or west). Latitude and longitude are divided in degrees (°), minutes (‘) and seconds (“).

Are lines of latitude?

Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallels. … The Equator is the line of 0 degrees latitude.
