How to tell the direction when you get lost at night?

1, I don't know the direction in the mountains. At this time, I can observe the rocks. The wet side covered with moss is north, and the dry glossy surface is south.

2. If there are ants in the lost place, you can observe the ant hole. In general, the ant hole is facing south.

3. There are stumps where you can't tell the direction. You can look at the annual rings. The width of the annual rings is south, and you can also observe a tree. The dense side is south, and vice versa.

4. Get instant results in the open space during the day, and write down the positions of the two shadow vertices at different times. The two points of the middle vertical line are due north, and you will find the north direction.

In clear weather, it is a good way to make your watch clock point to the direction of the sun. The bisector of the angle between the hour hand and twelve o'clock points to the north, as long as you have a watch.

6. If you get lost at night, you can tell the direction by observing the Polaris in the sky, but only if you know the Polaris and find the right direction, you'd better write it down and wait until you walk during the day.

A guide on earth

The geographical direction is not exactly the same as the usual direction, mainly referring to the east, west, south and north. The east is the same direction as the earth's rotation, the west is the opposite direction to the earth's rotation, and the east-west direction is also the direction of latitude circle. There is no end to the east-west direction on the earth. If we start from somewhere along the latitude direction and go east, we will never reach the end of the east, just walk around the latitude circle.

On the contrary, the north-south direction on the earth is polar. When we start from the equator and go north or south, we will finally go to the North Pole and South Pole, and when we cross the North Pole or South Pole, the direction will change. In the North Pole and South Pole, there is no east or west direction. There is only one direction in the North Pole-south; There is only one direction in Antarctica-north.

When we get a map without bearing marks, how can we determine the direction of a place on the map? First, let's see if the map is marked with latitude and longitude lines. The latitude indicates the east-west direction and the longitude indicates the north-south direction. If the edge of the map is marked with orientation marks, then the orientation needle arrow refers to the north. If there is no mark on the map, it means that it is north above, south below, west on the left and east on the right.
