What natural compasses are there in the wild?

Polaris, Moon, Tree Wheel, Bamboo and Ant Cave are all famous natural compasses.

1, Polaris

What is nature's compass? Polaris is the best natural compass in nature. Polaris, also known as Polaris and Purple MSI, refers to the star closest to the north celestial pole, that is, a bright star at the North Pole of the earth. Looking for Polaris at night can determine the direction. If you want to find the North Star, you must first find the Big Dipper, which looks like a water spoon. When you look at the two stars (Tian Xuan and Tian Shu) beside the water spoon, their brightness is about five times that of Polaris.

2. the moon

What is a natural compass? The moon is the only natural satellite on the earth. It reflects sunlight and is the most common compass in nature. Because of the different running directions, the receiving service often changes. At night, the moon rises in the east and sets in the west, receiving different images such as spheres, semicircles and new moons, which are called "moon phases".

The change of the moon phase has certain regularity in time and direction. As long as we know the moon phase and time, we can find the direction. For example, the direction of the moon at night is: the first quarter moon, 6 pm in the south and12 pm in the west; 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; The last moment of the moon is 0/2 o'clock in the east at night and 6 o'clock in the south the next morning.

3. Tree rings

After the trees are cut down, many concentric rings can be seen on the stump, which are called rings in botany. People have realized that tree rings record the ever-changing traces of nature and are extremely valuable scientific data. As a compass of nature, trees usually face south when the rings are wide and face north when the rings are dense.

They grow faster in the south than in the north, and the spacing is larger. There are sparse annual rings on the south side of the tree. The reason is that the south is sunny. There is more sunshine and rain than in the north. The south side gets more nutrition and becomes stronger, so the growth ring appears sparse; Similarly, the north side is denser, because it is dark and has less nutrients than the south side.

4. Bamboo

Bamboo is called "four gentlemen in flowers". Although there are many kinds, many of them originated in China, which is a symbol of China's inheritance. Many people may not know that bamboo can also be used as a compass for nature. Generally speaking, you can tell the direction according to the color, stripes, leaves and outline of bamboo.

Bamboo is green to the south, and the shady side, that is, the north, is easy to grow moss; The stripes of bamboo and the tips of most leaves point south; From the profile, the south side is more dispersed and less dense than the north side; In the absence of wind, the top of bamboo leans to the south.

5. Ant Cave

If you look closely at the nest, you will find that the orientation of the nest can also be used as a compass for nature. Because the hole of the ant hole is basically facing south, you can know your direction when you see the ant hole. The ant cave faces south, and it is not wet, so it is convenient to find food. This is mainly the habit of ants. They like warm soil and usually live in dry and non-humid areas. So, the nest faces south.
