Which statement accurately describes lines of latitude, also called parallels, on a map? a. They measure distance east and west of the equator.

b. They measure distance north and south of the prime meridian.

c. They measure distance east and west of the prime meridian.

d. They measure distance north and south of the equator.

Answers

They measure the distance north and south of the prime meridian is the statement accurately describes lines of latitude, also called parallels, on a map. Hence, option B is correct.

What are lines of latitude?

Latitude lines, often called parallels, are imaginary lines that divide the world in half. They run from east to west, yet they calculate your distance north or south.

The equator is the most well-known parallel. At 0 degrees latitude, it evenly divides the Earth into the Northern and Southern hemispheres.  Meridians are imaginary lines that divide the world; they are also referred to as lines of longitude.

Running from north to south, they gauge the distance either east or west, from pole to pole. The prime meridian travels through Greenwich, England, at a longitude of 0 degrees.

Thus,  option B is correct.
