How to distinguish the four directions of southeast, northwest, and northwest

There are several ways to distinguish the four directions:

1.Use the compass: Place the compass on flat ground, hold the map, adjust the direction of the map so that it matches the direction of the compass, and then make the north on the map point to the same as the compass's pointer, in this case, the direction of the compass is south.

2.Use of plants: In the northern hemisphere, trees are generally dense in the south and sparse in the north. In the Southern Hemisphere it is the opposite.

3.Look at the sun: At sunrise, the direction facing the sun is east, behind is west, right is south, and left is north. At noon, facing the sun is south, with north behind you, east to your right, and west to your left.

4.At night, the North Star is north on the north side and south on the other.

5.Use the stars: Take the North Star as the standard, first find the Big Dipper, and take the two stars at the mouth of the spoon to draw a straight line as an extension line, and at the place where it extends to about twice the distance, you will see a very bright star, which is the North Star. The direction of the North Star is north.

6.Mobile map: Open the map software of your phone, due to the rotation of the earth, an arrow will always be displayed on the map, the head of the arrow points to the south, and the tail is the north.

The above are several commonly used methods, and you can choose the appropriate method according to the actual situation.

Facing the sun, the front is east and the back is west. When there is the sun, look at the sun, walk towards the sun in the morning, the front is east, the back is west, the left is north, and the right is south, and at night it is the opposite.

The four directions of southeast, northwest, and northwest are easy to distinguish. First, find a reference.

Generally look for the sun, the sun rises and sets, the direction of the sun rises is east, the direction of the sun setting is west, the east and west are 180 degrees, and then press clockwise.

To identify the two directions of south and north, 90 degrees clockwise in the east is south, and 90 degrees clockwise in the west is north, so that the southeast, northwest and northwest are separated by 90 degrees.

Wake up in the morning. Facing the sun. The front is east. The back is west. To the right is South. On the left is North.

To determine the direction on the map, first of all, see if there are longitude and latitude lines, if there are longitude and latitude lines, use the longitude to determine the north-south direction, and use the latitude lines to determine the east-west direction.

Secondly, if there is no latitude and longitude line, just look at the "pointing mark", generally pointing to the north, after determining the direction of due north, turn 90 degrees clockwise, and determine the three directions of "southeast and west". Again, if there are no latitude and longitude lines and pointing markers, use "up north and down south, left west and right east" to determine the direction.

In real life, we often use the judgment of the southeast, northwest, and northwest directions, and we can use geographical things to determine the direction. If you are in the city, then it is more convenient to use road signs to determine the direction, of course, you can also use many mobile phone apps to determine the direction. In our country, if you can see solar panels, you can use the orientation to roughly determine the position due south.

If you are in the wild, we can also use the sun's bearing to determine the "southeast, northwest" direction. Excluding high latitudes, whether in the northern and southern hemispheres, the sunrise and sunset directions are determined, that is, "rising in the east and setting in the west", so we can roughly determine the direction according to the sunrise and sunset.

The origin of the southeast, northwest, and northwest

The ancients relied on natural scenes to identify the four directions, and created the words for southeast, north, west and other directions.

East: Ri in the wood, which means the rising sun, and the place where the rising sun rises is the east.

South: The outer frame is the deformation of the wooden character, the meaning of the sheep, that is, the grass and trees bear the full sunshine in the south, and the branches and leaves will grow luxuriantly, so the sunny place is the south.

West: The ancient form is that the bird is on the nest, that is, the sun sinks in the west and the bird returns to the nest to perch, and the bird returns to the nest, which becomes the direction of the word west.

North: The ancient ** became two people facing each other, and the palace room mostly sat in the north and faced south, and the back of the north became the north of the north.

Here's how to identify them:1. Polaris: Polaris is the best compass, and the direction in which it is located is due north.

2. Immediate results: In the clear day, insert a straight skewer vertically into the ground, form a shadow under the irradiation of the sun, put the stone at the apex of the shadow, about fifteen minutes later, when the straight skewer shadow moves to another place, put another piece to the shadow fixed point, connect the two stones into a straight line, the side facing the sun is south, and the opposite direction is north.

3. Use the watch: the hours are folded half to the sun, 12 refers to the north, for example, four o'clock in the afternoon is 16 o'clock, 16 divided by 2 is equal to 8, the 8 o'clock position is aimed at the sun, and the direction of the 12 o'clock position is the north.

4. Use tree rings: the rings on the south side of the tree ring are sparse, and the rings on the north side of the tree ring are relatively tight.

5. Use ant caves: Ant caves are mostly located in the south of big trees, and the entrance of the cave faces south.

The direction of the sun rising in the early morning is east, and the direction of the sun setting in the evening is west, and the north and south can be distinguished according to the relative position relationship of each direction, "up north, down south, left west, right east". If it's a night when the stars are bright, you can find the direction by looking for the location of the North Star, which is in the north.

The direction can also be determined based on the growth and development of the plant: usually the dense canopy is on the south side and the north on the other. The direction can also be judged according to the morphology of the tree's rings

The sparse side of the rings points to the south, and the dense side points to the north. In areas where there are a lot of rocky outcrops, you can also look at the rocks to determine the direction: the mossy side of the rock is the north side, and the dry and bare side is the south side.

With a watch, a watch that needs a dial is 4 p.m., and it is 16 o'clock in 24-hour clock, and then divide by 2 to get 8. If the "8" on the dial is aligned with the sun, then the direction of the "12" will be north.

Immediate results: In a clear day, put a straight skewer vertically into the ground, the straight skewer will form a shadow under the sun's illumination, place the stone at the apex of the shadow, about 15 minutes later, when the straight skewer shadow moves to another place, put another one to the shadow point, connect the two stones into a straight line, the side facing the sun is south, and the opposite direction is north.

The method is as follows: 1. Observe the celestial phenomena: the most common observation of celestial phenomena is to observe the North Star, at night, find the Big Dipper constellation shaped like a spoon, there is a bright star at seven times the distance at the end of the spoon, that is, the North Star, directly below it is due north, clockwise is east, south, west.

2. Sun and Moon: The sun rises in the east and sets in the west, and a general direction can generally be seen when observing the sunset and the sunset.

3. It can also be determined by the following methods: erect a straight stick on a flat ground (Liang Tan Bei is more than 1 meter high), first make a mark at the top of the shadow of the straight stick (such as putting a stone), the shadow of the brother of the straight stick will move with the movement of the sun, 10 to 60 minutes later, make another mark at the top of the shadow of the stick, draw a straight line between the two marks, and.
