Some things simply beg for simplification and cartographers were able to see the advantage in this basic premise, weights and measurements may have come first, but soon everyone understood the concept of directions.
North is always "up" on maps.
On standard maps and globes, the Equator goes side to side.
As arbitrary as it may be, it is up and down, side to side. The x and y axis' it's the way maps were first drawn and have always been. A compass points north. The sign of the cross starts N S E W.orbefore the invention of the compass people were able to measure their latitude (north - south) with the aid of the Polaris. It took much longer before they were able to determine their longitude (east - west).
It is always in the sky but when it is dark on one side of the earth, the sun is up on the other side. So yes, the sun is always up.
They aren't if you turn them right-side up.
North - South; up and down most maps.
The idea or belief that north should always be up and east at the right was established by the Egyptian astronomer Ptolemy (90-168 AD). "Perhaps this was because the better-known places in his world were in the northern hemisphere, and on a flat map these were most convenient for study if they were in the upper right-hand corner," historian Daniel Boorstin opines. Mapmakers haven't always followed Ptolemy; during the Middle Ages, Boorstin notes, maps often had east on top--whence the expression "to orient." But north prevailed over the long haul. By the time Southern Hemispheroids had become numerically significant enough to complain, the north-side-up convention was too well established to change.
Parallels are lines that go up and down the map, latitudes are lines that go across the map from side to side.
According to Google.com Maps: Vacaville Calif. is 165 miles South of Redding, Calif. It's down if South is Down, and North is Up, which it is on most maps.
The side of the moon facing the sun is always lit up, while the opposite side remains in darkness. This phenomenon is due to the moon's synchronous rotation, which results in one side always facing the sun.
Up
because it is up north.
