What are bearings (in geography)?

i wanna know what bearings are in geography....

Update:

and whats the difference between bearings and degrees?

or are they the same thing?

For your followup question. As the answers say, perhaps in too much detail, a bearing and a heading are measured in degrees, like distance is measured in miles.

If my ship is headed east, its heading is 90 degrees because north is the starting point and there 360 degrees in a circle (because it is easy to divide by many different numbers (2, 4, 6, 9, 10, 12, 15, 30, 60, 72, 90, 180).

If your ship is approaching, my mate might report "Captain, a large cargo vessel is on a bearing of 75 degrees to port." Using the word bearing means "angle relative to the centerline of my ship." Two ships (or cars or planes) that hold the same bearing for a period of time will collide unless on parallel courses at the same speed.

Bearings Geography

Compass bearing in Geography is used to determine or give the exact location of a place. This is done using degree measure. When working with compass bearing, you should always measure the angle from the North cardinal. Below is some useful information for you to read.

A compass can tell you which direction you are going, this is known as your heading. A compass can also tell you the direction an object is from you. Those directions are known as bearings. Once bearings of objects are known, you can use a map or a chart to find out where you are. You can then figure out which direction you want to go and use the compass to make sure you follow that heading.

A compass works by using a magnetized needle that orients itself with the earth's natural magnetic field to point in the direction of magnetic north. The bearing or heading is then read from numbers on the compass to indicate directions such as north, south, east, or west.

The numbers that are on a compass represent degrees of a circle. The degrees are numbered from 0° to 360°, clockwise around the circle, with 0° and 360° being the same thing. 0° (and by default 360°) represents north; 90° represents east; 180° represents south; 270° represents west.

If your heading, the direction you are going, is toward the east, you are said to be on a heading of 90°. Likewise if your heading is toward the west, you are said to be on a heading of 270°. Bearing Example

If you are on a boat (Boat A)and there is a lighthouse directly east of you, the bearing of that lighthouse is 90°. Another lighthouse directly south of you, would be at a bearing of 180°. It does not matter which way your boat is pointing, what we are measuring is the direction of the lighthouse from the boat as it would be shown on a chart.

Compasses are sensitive to magnetic fields, and can be affected by small metal or magnetic objects. If a compass is used near a metal belt buckle, a camera, a radio, or other metal or electronic items, it may not be accurate. The first step when using a compass is to make sure that there are no metal objects nearby. For some compasses, such as those on a metal ship or airplane, this is not possible. In those cases special steps are taken to correct for the "compass error", also known as magnetic deviation. Note that magnetic deviation is different than magnetic variation, both of which are described below.

Compasses can either be hand held or mounted on an object such as a boat. A hand held is used by pointing it toward the object you are interested in. The marks on a compass are then read to find the bearing of the object.

A compass attached to a boat should be installed so that the bearing taken is of the heading of the boat is in the direction indicated by the compass. Taking a bearing of an object not directly ahead of the boat can be difficult, and in those cases a hand bearing compass might be preferred.

Bearings taken from a compass are usually read in degrees of a circle with 0° being toward the magnetic north pole, 180° is south, 90° is East and 270° is West. Bearings taken by a compass are magnetic bearings, and not true bearings. When using a compass, you need to take into account the difference between true and magnetic north.

In marine navigation, a bearing is the direction one object is from another object, usually, the direction of an object from one's own vessel. In aircraft navigation, a bearing is the actual (corrected) compass direction of the forward course of the aircraft. In land navigation, a bearing is the angle between a line connecting two points and a north-south line, or meridian
