## Is time based on longitude or latitude?

Divided up into an hourly rate, the earth rotates 15 degrees every hour (360/24). This number plays an important role in determining time zones. An important factor in determining time zones is the lines of latitude and longitude. Imaginary lines known as latitude and longitude divide the Earth.

## Do time zones always follow the lines of longitude?

In fact, because time zones do not follow neatly along lines of longitude, there are many places where three or more time zones meet.

## Does Latitude Affect time?

At latitude 0° (the Equator) day length will be approximately 12 hours. Areas on the Equator have a constant 12 hours of day light all year round. As latitude increases to 80° (polar circles – north or south) day length can be seen to increase to 24 hours or decrease to zero (depending on time of year).

## Do all places on the same line of longitude have the same time?

The earth rotates from west to east, day starts at different times in different places. Places east of the Greenwich meridian experience sunrise earlier than the place lying west of the prime meridian. All the places situated along the same meridian will have the same local time.

## Why are latitudes measured in degrees?

Latitude and Longitude are angles. The most common way to measure an angle is in degrees. Because the Equator goes all the way around the Earth, latitude is always between -90 (South Pole) and +90 (North Pole).

## Which way does latitude run?

Lines of latitude (parallels) run east-west around the globe and are used to measure distances NORTH and SOUTH of the equator. Since the equator is 0 , the latitude of the north pole, 1/4 of the way around the globe going in a northerly direction, would be 90 N. This is the highest latitude possible.

## Is Latitude side to side?

Lines of latitude are imaginary lines that run in an east-west (side-to-side) direction around the earth. Because the lines of latitude are parallel to each other, they are often referred to as parallels of latitude.

## How can you tell if longitude is east or west?

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.

## Why do the two circles of latitude never touch?

The Spherical Shape of the Hemisphere goes on tapering towards the Poles, eventually Slicing the Earth from the Equator by each line of the Latitude by the Smaller Circles until they meet at the Poles. Therefore the PARALLELS OF THE EQUATOR or Circles of Latitudes never meet Together or even touch each other.
