## Do latitude lines go up and down?

Introduce the concepts of latitude and longitude. 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 longitude the first or second number?

Longitude, the lines that run up and down on a map or globe, is always listed second when assigning a measurement. The prime meridian is found at 0° longitude, and there are 180° going both east and west from the prime meridian to the International Date Line.

### What are the two numbers for latitude and longitude?

The two numbers are a location’s latitude number and its longitude number (“Lat/Long”). Using Lat/Long is different from using a street address. Instead of having a specific street address, Lat/Long works with a numbered grid system, like what you see when you look at graph paper.

### How is a minute of longitude divided into 60 seconds?

Each minute of longitude can be further divided into 60 seconds. 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.

How are latitude and longitude lines work together?

How Latitude and Longitude Work Together. There are 60 minutes in each degree. Each minute is divided into 60 seconds. Seconds can be further divided into tenths, hundredths, or even thousandths. For example, the U.S. Capitol is located at 38°53’23″N, 77°00’27″W (38 degrees, 53 minutes, and 23 seconds north of the equator and 77 degrees,…

How are the degrees and longitudes of the earth related?

How Latitude and Longitude Work Together. To precisely locate points on the earth’s surface, degrees longitude and latitude have been divided into minutes (‘) and seconds (“). There are 60 minutes in each degree.
