## Are lines of longitude also called parallels?

The lines running North to South are called “Meridians” or “lines of longitude” (Figure 2), while the lines running East to West are called “Parallels” or “lines of latitude” (Figure 3). Note that the lines are parallel when we look at the earth from the equator.

## Are latitude lines always parallel?

Horizontal mapping lines on Earth are lines of latitude. They are known as “parallels” of latitude, because they run parallel to the equator.

## Are lines of longitude parallel to the equator?

The lines from pole to pole are lines of constant longitude, or meridians. The circles parallel to the Equator are circles of constant latitude, or parallels. The graticule shows the latitude and longitude of points on the surface. In this example, meridians are spaced at 6° intervals and parallels at 4° intervals.

Equator

## How many imaginary lines do we have?

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.

## What is another name of longitude?

Longitude is the measurement east or west of the prime meridian. 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.

## What’s another name given to the main line of longitude?

The lines are called meridians of longitude and they are also measured in degrees (°) and minutes (‘). The most important line of longitude is the Greenwich or Prime Meridian (0°). This line runs through the Greenwich Observatory in London. All the other lines of longitude are given a number between 0° and 180°.

## What are the five important latitudes?

Important lines of latitude:

• the equator (0°)
• the Tropic of Cancer (23.5° north)
• the Tropic of Capricorn (23.5° south)
• the Arctic circle (66.5° north)
• the Antarctic circle (66.5° south)
• the North Pole (90° north)
• the South Pole (90° south)

## Is longitude a circle?

Longitudes are, therefore, imaginary circles that intersect the North and South Poles and the Equator. Half of a longitudinal circle is known as a Meridian.

## Do longitude lines go up to 90 degrees?

Lines of longitude go from zero at the Prime Meridian up to 180 at the International Date Line. The designator of east or west will indicate the relative direction the line of longitude is from the Prime Meridian.

## How many miles are between longitude lines?

60 nautical miles

## Is north latitude or longitude?

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.
