What compass exists in nature? Write at least thirteen types.

1. Shanyin is in the south and Shanyang is in the north. 2. Annual rings. 3. Ant cave. 4. Big Dipper. 5. Sunshine. 6. The sun. 7. Moss. 8. Polaris. 9. Wild geese. Wild geese fly south. 10. The shape, brightness and bright side of the moon. 11..The melting of snow. 12. Single plant. 13. Calculation based on terrain.

1. Shanyin is in the south and Shanyang is in the north.

The shady side of the mountain is in the south, and generally has dense vegetation. The sunny side of the mountain is to the north, with sparse vegetation and lots of sand and gravel.

2. Annual rings

The wide annual rings face south, and the dense ones face north.

3. Ant caves

Observe the ant caves. Most of the cave entrances face south.

4. The Big Dipper

At night, the stars are connected in a spoon shape, pointing north.

5. Sunlight

Put a pole vertically at noon. When the sun is upright at noon, there is no shadow. As time goes by, the sun will slowly move westward. At this time, the shadow will be The direction is east.

6. Sun

Use a straight wooden stick and the sun to determine the direction. The main method is: use a straight pole (straight wooden stick) to make it perpendicular to the ground, and place a stone at the vertex A of the shadow of the straight pole; after about 10 minutes, when the vertex of the shadow of the straight pole moves to B, then Place a stone. Connect two points A and B into a straight line. The direction of this straight line is the east-west direction. The direction perpendicular to the line AB is north-south, and the end facing the sun is south. ?

7. Moss

11.. Melting of snow?

The place where the snow melts is towards the south

12. Single plant

Lush One side is south, the other side is north.

13. Calculation based on terrain

If in our country, the terrain is higher in the west than in the east, we can consider it together with the flow direction of the river to get the direction.

, can be considered together with the flow direction of the river to derive the direction.
