## Is longitude supposed to be negative?

Each line of longitude runs north and south and measures the number of degrees east or west of the Prime Meridian. Values range from positive 180 to negative 180 degrees.

## How do you read a negative latitude and longitude?

“A negative number for latitude such as -7.48° (if it’s negative the minus is always shown) is a SOUTH latitude!” “And for longitude if there’s no E or W and if the number is positive (such as 128.3425° or +128.34°) then the longitude is EAST.

## How do you know if longitude is east or west?

To measure longitude east or west of the Prime Meridian there are 180 vertical longitude lines east of the Prime Meridian and 180 vertical longitude lines west of the Prime Meridian so longitude locations are given as __ degrees east or __ degrees west.

## Is north latitude or longitude?

If you take a look at a map or globe of the world you may notice lines running east-west and north-south. The lines run east-west are known as lines of latitude. The lines running north-south are known as lines of longitude.

## Why is longitude a negative number?

If the number is negative it represents south of the Equator. The line of longitude is read as 2 degrees (2) 10.4418 minutes (10.4418) east. The coordinate for the line of longitude represents east of the Prime Meridian because it is positive. If the number is negative it represents west of the Prime Meridian.

## Which way is negative latitude?

Positive latitudes are north of the equator negative latitudes are south of the equator. Positive longitudes are east of the Prime Meridian negative longitudes are west of the Prime Meridian. Latitude and longitude are usually expressed in that sequence latitude before longitude.

## Does latitude go first?

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 (“). There are 60 minutes in a degree and 60 seconds in a minute (similar to measuring time).

## What distance is 1 degree of longitude?

One degree of latitude equals approximately 364 000 feet (69 miles) one minute equals 6 068 feet (1.15 miles) and one-second equals 101 feet. One-degree of longitude equals 288 200 feet (54.6 miles) one minute equals 4 800 feet (0.91 mile) and one second equals 80 feet.

## How do you write out latitude and longitude?

When writing latitude and longitude write latitude first followed by a comma and then longitude. For example the above lines of latitude and longitude would be written as “15°N 30°E.”

## How do you know if longitude is north or south?

2 Answers. Latitude is positive in north and negative in south. Similarly Longitude is positive in east and negative in west.

## Who bisects Earth?

The Equator or line of 0 degrees latitude divides the Earth into the Northern and Southern hemispheres.

## Is 0 degrees north or south?

Zero degrees latitude is the line designating the Equator and divides the Earth into two equal hemispheres (north and south). The Equator is the line of zero degrees latitude around the middle of Earth. Image: NASA public domain. Zero degrees longitude is an imaginary line known as the Prime Meridian.

## What is the 0 latitude line called?

The Equator
The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator with 90 degrees north of the Equator and 90 degrees south of the Equator. The latitude of the North Pole is 90 degrees N and the latitude of the South Pole is 90 degrees S.Nov 6 2012

## What are examples of longitude?

For example the longitude of Paris France is 2° 29′ E (2 degrees 29 minutes east). The longitude for Brasilia Brazil is 47° 55′ W (47 degrees 55 minutes west). A degree of longitude is about 111 kilometers (69 miles) at its widest. The widest areas of longitude are near the Equator where the Earth bulges out.

## How many longitudes are there?

360

Lines of latitude are known as parallels and there are 180 degrees of latitude in total. The total number of latitudes is also 180 the total number of longitudes is 360.

## What is difference between longitude and latitude?

Latitudes are measured in degrees. Longitudes: The vertical lines running north-south join the two poles.

What is the difference between Latitude and Longitude?
Latitude Longitude
It is known as parallels It is known as meridians
The length of the lines are different The length of the lines are the same

## Is negative latitude East or West?

Latitude/Longitude Formats

Note that negative latitudes represent the southern hemisphere and negative longitudes represent the western hemisphere. The fractional portion of decimal degrees are instead represented as the number of “minutes” between 0 and 60.

## Why do lines of latitude never intersect?

Circles of latitude are often called parallels because they are parallel to each other that is planes that contain any of these circles never intersect each other. A location’s position along a circle of latitude is given by its longitude. … A circle of latitude is perpendicular to all meridians.

## Is latitude north or west?

Lines of latitude run east and west. Lines of latitude run horizontally around the Earth and tell you how far north or south you are from the Equator.

## How long does it take Earth to pass one longitude?

The earth takes 24 hours to make one rotation which is 360° of longitudes.

## How many miles is 4 degrees latitude?

Each degree of latitude is approximately 69 miles (111 kilometers) apart. The range varies (due to the earth’s slightly ellipsoid shape) from 68.703 miles (110.567 km) at the equator to 69.407 (111.699 km) at the poles.

## Are degrees minutes seconds accurate?

Spatial Precision in DMS

The precision of geographic coordinates varies based on how they are formatted and regularly see coordinates in DMS with just the degrees without a decimal or minutes after them. The degrees are only precise to about 111 km so the coordinates are basically worthless.

## Where are the exact places on earth?

To help us locate places on the earth’s surface we use a coordinate system. This coordinate system is like placing a giant grid over the earth. This grid has lines extending from east to west called lines of latitude and lines extending from north to south called lines of longitude.

## Can you shorten coordinates?

When writing latitude and longitude write latitude first followed by a comma and then longitude. For example the above lines of latitude and longitude would be written as “15°N 30°E.”

## How do coordinates describe the places on earth?

Overview explaining the coordinate system of latitude and longitude which is used to describe the location of any place on Earth’s surface. … Given in degrees minutes and seconds geocentric latitude is the arc subtended by an angle at Earth’s centre and measured in a north-south plane poleward from the Equator.

## Which way does latitude run?

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.

## Are GPS coordinates the same as latitude and longitude?

GPS coordinates are a unique identifier of a precise geographic location on the earth usually expressed in alphanumeric characters. … GPS (global positioning system) coordinates are usually expressed as the combination of latitude and longitude.

## Why do we have 360 longitudes and only 181 latitudes?

Longitude lines runs from North to south pole means a complete circles and hence covers 360 degrees and that is why there are 360 longitudes. … Each section from equator to pole is 90 degrees and two poles have 2 quarters of circle/globe hence 90X2 180 lattitudes. adding the Equator it becomes 181 latitudes.

## What are parallels of latitude answer?

Complete answer: Parallels of latitude are the circles which are parallels from the equator to the poles whereas the lines of reference running from the North Pole to the South Pole are called meridians of longitude. … The meridian which passes through Greenwich is also known as Prime Meridian.

## What are parallels latitudes?

Parallels of latitudes can be referred to as the parallel circles from the equator up to the poles. They are usually measured in degrees. … Its distance from the equator to either of the poles is almost one-fourth of a circle round the earth it will measure ¼th of 360 degrees that is 90°.

## IS NULL Island real?

Null Island is an imaginary island located at 0°N 0°E (hence “Null”) in the South Atlantic Ocean. This point is where the Equator meets the Prime Meridian.
