What direction do lines of longitude run?

What are lines of longitude known as?

From where to where do lines of longitude run?

All lines of longitude are equal in length.

How many degrees of longitude are there?

What is the longitude line of 0 degrees known as?

What hemispheres does the Prime Meridian divide the world into?

What happens to the distance between lines of longitude as you move toward the poles?

What is the distance between longitudes at the equator?

What is the line of longitude where the degree is zero known as?

What is another name for the Prime Meridian as it passes through the Royal Observatory?

What is the line on Earth where one calendar day becomes the next?

The International Date Line is always found 180 degrees from the Prime Meridian.

How many one-hour slices and two 30-minute slices are there that divide the world into different time zones?

What happens to the calendar when traveling from east to west over the International Date Line?

Divides the Earth into the Eastern and Western Hemispheres.
Passes through the Royal Observatory in Greenwich, England, and is also called the Greenwich Meridian.

The distance between longitude lines is consistent at the equator, approximately 69 miles (111 km).
As latitude increases, particularly toward the poles, the distance between lines of longitude decreases to zero at the North and South Poles.

Located generally at 180 degrees opposite of the Prime Meridian.
Adjusts around specific regions and islands to prevent splitting countries into differing calendar days.

The world is segmented into 23 one-hour slices and two 30-minute slices for time zones.
Crossing the International Date Line when traveling from east to west adds a day to the calendar.
