What phenomena in nature can help to identify the direction?

1, using the sun to distinguish, it is immediate. As we all know, the sun rises and sets in the west, and the direction of the shadow of the object in the morning is the west. 12, the sun is due south, and the shadow points to the north. In the afternoon, the sun is due west and the shadow points to the east.

With the moon, it rises and sets regularly. The moon rises 48-50 minutes later than the previous day. For example, on the fifteenth day of the lunar calendar 18, the moon rises in the east. On the twentieth day of the lunar calendar, the distance is 5 days, it rises about 4 hours later and appears in the eastern sky at about 22: 00. The phase change of the "full moon" is also regular.

Before the fifteenth lunar month, the bright part of the moon is on the right, and after the fifteenth, the bright part of the moon is on the left. The first half of the month is the first quarter moon, the middle of the month is the full moon, and the second half is the second quarter moon. Every month, the moon rises and falls according to the above two laws.

3. Look at the Big Dipper, which is like a huge spoon. It's easy to find in a clear night sky. From the direction of the extension line of the two stars on the spoon, there is a star about five times brighter than it, that is, Polaris.

4. Face shadow observation method: find a small wooden pole to stand in the center of the watch and rotate the angle of the watch so that the small wooden pole coincides with the hour hand. At this time, the midpoint of the angle formed by the hour hand and several points is the north, and the other end is the south. In addition, you can mark along the road to facilitate the return to the original road. You can carry a red cloth strip with you, tie it to a tree, or mark it with stones.

5. Observing the sky: The most common observation of the sky is observing the Polaris. At night, under the moonlit night sky, we will always find the Beidou constellation shaped like a spoon. There is a bright star seven times from the end of the spoon. That's Polaris, and just below it is the north.
