Which way do meridians run and what do they measure?

Answer 1

Lines of latitude run laterally across the earth from east to west. They measure the degrees of arc north and south of the equator which is at 0 degrees. Washington, DC, lies about 38 degrees North.

Answer 2

A meridian on a map doesn't measure anything, any more than a mark on a ruler does.

A meridian is a collection of all the points on Earth that have the same longitude.

The longitude of any of them is the angle, measured east or west on the curved

surface of the Earth, between the Prime Meridian and that point.

Answer 3

Meridians are imaginary lines that run from North to South. The lines are the lines of "longitude" that circle the Earth. The main line is at zero degrees longitude, is called the "Prime Meridian", and runs directly through the town of Greenwich, England. Its opposite, at 180 degrees longitude, is the "International Date Line" and runs down the middle of the Pacific Ocean.

They are used to measure time as the term "meridian" comes from the Latin "meridies", which means "mid day". The sun crosses a given meridian midway between the times of sunrise and sunset on that meridian. This term also gives rise to the abbreviations AM and PM (which differentiate the morning hours from afternoon hours on a 12 hour clock). AM means Ante (before) Meridian and PM means Post (after) Meridian.

Answer 4

latitude lines are imaginary lines running around the earth hoizontally from the equator wich is line 0 then from there they go north to the pole to 90 degreees north then south from the equator to the south pole to 90 degrees south all these lines are parallel to the equator hope this answers your question if not say so

Answer 5

Meridians run north-south and measure distances east-west on the Earth's surface. They are lines of longitude that converge at the poles and help pinpoint locations on a map or globe.
