Excuse me, how do rock fossils tell the direction in the wild?
1. Find an eye-catching stone where there are many stones. The mossy side of the rock is the north side, and the dry and bare side is the south side.
2. Use the compass needle: When the magnetic needle of the compass needle is at rest, its N-end (usually marked) points to the north. Compass or compass can not only measure the true north direction, but also measure the specific direction of the target by aiming the compass collimator at the target or aiming the 0 scale on the dial at the target, so that the target, the 0 scale and the magnetic midpoint are on the same straight line. After the compass is horizontally stationary, the scale pointed by the N end is the direction from the measuring point to the target, for example, the N end of the magnetic needle points to 36.
The sun rises in the east and sets in the west, which is the most basic way to tell the direction.
4. Use Polaris: Polaris is located in the northern sky. When observed, its height from the ground is approximately equivalent to the local latitude. When looking for it, it is usually determined according to the Big Dipper (Ursa Major) or the W star (Hou Xian). The Big Dipper is seven bright stars, shaped like a spoon. It extends a straight line from the spoon head to the spoon mouth, which is about five times the distance between the two stars. There is a slightly darker star, the Polaris.
5. Independent trees usually have lush branches and leaves in the south, smooth bark, sparse branches in the north and rough bark. The south is usually dense with grass, while the north is wet and covered with moss.
