Linlin got lost in the forest. There are several ways to help him find his own way.

The best way is to call 1 10, but there are others. The first "compass" is the sun. We live in the northern hemisphere. Except in the south of the Tropic of Cancer, the sun always shines from the south. In this way, the north-south direction can be easily determined. We all know that the sun rises in the east and sets in the west. The sun rises in the east in the morning, sets in the west at night, and is in our south at noon. However, you should not apply this method dogmatically. If you are in the southern hemisphere or between the Tropic of Cancer, the situation is another matter. The second kind of compass is 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. The third kind of compass is Polaris. Polaris is the best compass, and its direction is due north. But how to find Polaris? In fact, it is easy to find the familiar Big Dipper. The Big Dipper is like a water spoon. When the two stars on the side of the water spoon are stretched to about 5 times, there is a brighter star, the Polaris. On the opposite side of Polaris, there is also a constellation Andromeda, shaped like the English letter W, which can also help us find Polaris. Around 8 pm, if February-August, February 2- 10/October, you can use Ursa major to find Polaris, and Cassiopeia is better. The fourth kind of compass is 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. It can also be distinguished by tree rings. These rings face south in width and north in density. Because the south grows faster than the north, the annual ring interval is wider. The fifth kind of compass is snow. Similarly, take our northern hemisphere as an example. The snow on the southern hillside is denser and more granular. The snow on the northern hillside is softer and drier. When the snow melts, the snow on the south hillside melts more easily than the snow on the north hillside.

Add-Goose: Flying south in autumn.

Ant: The nest faces south.

You can also know from moss:

Moss is mostly in the north and less in the south.

If it is in the northern hemisphere, there are the following schemes-major premise: in the northern hemisphere! 1. During the day, you can use the watch guide to point any pointer at the sun, because the sun rotates 15 degrees in the sky every hour. If you use the watch as a protractor, you can see that the small grid between minutes is 360 degrees divided by 60 minutes, which is 6 degrees per grid. During the day, the local sun at 12 must be due south. If you get lost at 3 pm, you can point a needle at the sun, then multiply it by 15 degrees =45 degrees at 3 pm, then use the needle you choose as the starting edge, find 45 degrees counterclockwise, and the ending edge refers to the south. You can try. If you get lost in the morning, look clockwise. (o(∩_∩)o...)2. But if you get lost in the wild, you'd better have a compass. 3. It can also be judged by the color of the fruit that it is ripe in the south. Can be compared with apples. 4. Leaves are ok. The smooth side of the leaf is often south, which is convenient for photosynthesis, and the back of the vein is north.
