question
How do you measure latitude at the poles?
answer
latitude starts at 0 degrees at the equator and is always 90 degrees (either north or south) at the equator
question
How do you measure longitude at the poles?
answer
lines of longitude (or meridians) start and end at the poles
question
Are lines of latitude always the same distance apart?
answer
Yes, so any place to you stand on a certain line of latitude, you will always be the same distance from the poles
question

answer
No, they get closer together as they get closer to the poles, and further apart as the get closer to the equator.
question

answer
Whether it is east or west of the prime meridian, for example 110 degrees east, or 55 degrees west
question
Besides the equator, what does every measure of latitude have to include?
answer
Whether it is north or south of the equator, for example, 25 degrees north or 75 degrees south
question
In measuring location in latitude and longitude, which is stated first?
answer
Usually latitude (but it doesn't really matter, because you'll know which it is by whether it says north, south, east or west after the number)
question
Is this a possible location on the earth: 100 degrees north by 200 degrees east? Why or why not?
answer
No! Measures with north and south (latitude) only go up to 90 and measures of east and west (longitude) only go up to 180.
