Latitude lines go up to degrees at the North pole and ___ degrees down the South Pole.

Latitude lines go up to 90 degrees at the North pole and 90 degrees down the South pole.

Explanation:

Humans, in order to satisfy their needs, have created imaginary lines across Earth. One of these lines cut Earth from north to south, thus are roughly vertical, while the other ones cut Earth from east to west, thus are horizontal. The lines that run from east to west are called latitude lines, while the ones that run fron north to south are called longitude lines.

The latitude lines start off from the Equator which cuts Earth into two equal parts - Northern Hemisphere and Southern Hemisphere. The Equator has 0 degrees latitude and the latitude lines extend to 90 degrees north and 90 degrees south. These lines are used for navigation, determining coordinates, but are also good indicators of Earth's climate zones and biomes.
