What are the simple ways to tell the direction?

The simple way to tell the direction is Polaris, the sun and plants.

Using the sunny sun, we can easily know the east and west according to the sunrise and sunset, and we can also judge the direction, but it can only be a rough estimate.

Polaris Polaris is located in the northern sky, and its exposed altitude angle is equivalent to the local latitude, so you can find Polaris quickly. Usually according to the Big Dipper (Ursa Major) or the W Star (Fairy Queen). The Big Dipper is seven bright stars, shaped like a spoon. The place where the two β -α directions of the spoon extend about 5 times is Polaris. ?

When you can't see the Big Dipper, you can look for the North Star according to the constellation W after Fairy. Cassiopeia consists of five bright stars, shaped like a "W" letter, and the distance between the opening direction and the opening width of the letter is about twice that of Polaris.

As the saying goes, "Everything grows on the sun". After mastering this characteristic, even on a cloudy day without the sun, we can judge the direction by observation. For example, the grass in the south of big stones and tree trunks grows vigorously, and the grass in the south withers faster in autumn; Bark is generally smooth in the south and rough in the north. There are many cracks and protrusions on the northern bark of some trees, which is especially obvious in birch.

The gum resin from conifers and firs on the trunk is more in the south than in the north, which is easy to form a larger block; In autumn, many fruit trees bear more fruits facing south, especially apples, red dates, persimmons and oranges. The fruit changes color first when it is ripe. Moss growing on stones likes humidity, and the north is more prosperous; Most of the snow melts in the south first.
