If you get lost in the wild, the natural compass sentence mentioned in the original text:
First of all, the sun:
The sun is a faithful guide,
It shows you the way in the sky,
In the south at noon,
The shadow on the ground points to the north.
Second, Polaris:
Polaris is a street lamp,
It always hangs high in the north.
If you can recognize it,
You won't break in in the dark.
Third, the tree:
If it rains,
Dashu will also come to help.
The thick side of the leaves is the south,
The side with sparse branches and leaves is the north.
Fourth, snow:
Snow is particularly afraid of the sun.
Snow in the ditch will show you the way.
See which side of the snow melts fast and which side melts slowly.
You can tell the difference between north and south.
Extended data:
Several compasses in nature and their identification methods;
1, sun
Use a straight stick and the sun to determine the direction. The main method is: use a straight rod (straight wooden stick) to make it perpendicular to the ground, and put a stone at the vertex A of the shadow of the straight rod; After about 10 minutes, when the vertex of the shadow of the straight bar moves to B, put another stone. Connect point A and point B into a straight line, and the direction of this straight line is the east-west direction. The direction perpendicular to the AB line is the north-south direction, and the end facing the sun is the south.
2, the moon
On the third and fourth day, the crescent moon, the sunset is low in the west; On the eighth day of the seventh lunar month, the sun just went down, just above our heads. In half a month, as soon as the sun goes down, the moon rises in the east.
The direction of the moon at night is: the first quarter moon, in the south at 6 pm, and in the west at 12 pm. The full moon (14- 18) is in the east at 6 pm, in the south at 12 pm, and in the west at 6 am the next day. First quarter moon, in the east at night 12, and in the south at 6 o'clock the next morning.
3. Trees
This method is also very simple. For example, north of the Tropic of Cancer, the sun shines from the south, and the trees in the south get more heat from the sun than the trees in the north. Therefore, the branches of independent trees grow luxuriantly to the south and sparsely to the north.
4, the ant's cave
Observe the caves of ants, most of which face south.
5. Moss
Where there are many rocks, you can also find an eye-catching rock to observe. The covered side of the rock is the north side and the dry and exposed side is the south side.
6. Polaris
Polaris is a bright star in the sky due north. If you find Polaris at night, you will find due north.
