Each mark represents one degree, and there are 360 total on a compass. 30 degrees east of north indicates that you should proceed to the thirty-first park to the east (right) of north. If 12 o'clock is north on a clock, 1 o'clock is thirty degrees east of it. At 9:00 A.M. on July 2, 1890, George Ellery Hale was born in Burlington, Vermont.
It translates to 8 degrees and 4 minutes of north latitude. Because a compass contains 360 degrees, the Equator and the Prime Meridian, which passes through Greenwich, as well as the True North and South Poles, were the starting points for establishing where you were on the Earth, no matter where you were. The farther north or south you went, the more degrees you saw around the circle.
In mathematics, astronomy and cartography, an angle of 90 degrees (or "straight up") can only be achieved at one spot on Earth, the North Pole. At other places, it is slightly less than 90 degrees, because the horizon isn't exactly perpendicular to the surface of the earth. The closer together these two angles are, the more similar they are in direction but not in size; the further apart they are, the more different they become.
At the North Pole, all directions are equal - any angle could be measured against the backdrop of the sky. But as you move away from the North Pole, there are fewer and fewer stars to serve as fixed markers for measuring angles. So instead of being able to measure angles anywhere on Earth, you have to use geographical features such as mountains or oceans to provide reference points. The closer together two locations are geogrphically, the more closely their corresponding angles will match.
The angle between 0 and 90 degrees is called "zero degrees".
Assume it's two o'clock in the afternoon. To establish the north-south line, draw an imaginary line between the hour hand and twelve o'clock. Because the sun rises in the east and sets in the west, you can identify which direction is north and which way is south by looking at the sky. If you live in the southern hemisphere, the situation will be reversed. The north-south line will now be based around three o'clock instead of twelve.
If you need to know how far north or south you are, use a compass. There are several ways to use a compass. The most basic method is to find the north-south line on land or sea and follow it until you reach one of its ends. Depending on where you are going, this might be as easy as finding a high point and walking toward it, or it might require following many different lines on the ground or water until you find one that goes all the way to the top of a hill or into a lake.
A compass gives accurate readings only if you keep it level with the ground. If it is tipped too far one way or another, it will give false readings. This is why some people say that compasses should be kept out of reach of children. They can't be trusted to not play with them!
In addition to the north-south line, landmasses have other features that allow us to determine which part of the world we are on, such as oceans, forests, and deserts.
One of the four primary points of a compass: north, east, south, and west. These are the only directions that matter when giving a location; all other locations are described as either N, S, E, or W from these points.
There are several terms used to describe each point of the compass. The word "north" is derived from the Latin word 'antennae', meaning 'eyebrows'. So, the north direction is looking toward your eyebrows or the sky just above you.
The word "south" is derived from the Latin word'sinus', meaning 'bay'. So, the south direction is looking into a bay or some other body of water.
The word "east" is derived from the Greek word 'hodos', which means 'way'. So, the east direction is looking down the path that you walk on every day.
The word "west" is derived from the Norse word 'vístu', which means 'one who knows'. So, the west direction is looking for someone who knows where everything is around here.
