Dragonfly flying low: Because the air will be humid before it rains, and the dragonfly's wings are very thin, the moisture in the air will attach to the dragonfly's wings, which will put a certain amount of pressure on the dragonfly, so it cannot fly high. That's why people see a low-flying dragonfly and say it's about to rain, or why a dragonfly is flying low near a creek or waterbeach.

Nature is a magical and wonderful world, full of many mysteries that we don't know, and no matter how we explore and study, we will reap many surprises. Here are some of the mysteries that are still unsolved in nature.
1.Cosmic Dark Matter and Dark Energy: Scientists speculate that dark matter occupies a large part of the mass of the universe, accounting for about 98% of the mass of the universe.
The specific properties of these dark matter and dark energy are still being studied, and their existence and properties are crucial to solving many cosmic problems.
2.Bermuda Triangle's "Devil's Triangle": The Bermuda Triangle is considered a mysterious sea area where ships and planes have been missing for hundreds of years.
But scientists have yet to find out why. Early rumors and legends about the area add to its mystery and mystery.
3.Mysteries in the depths of the earth: The reality of the Earth's interior remains unanswered. For example, what is the material of the Earth's core, the specific causes and mechanisms of continental drift, etc., scientists are constantly exploring and researching in order to solve these mysteries.
4.The Origin of Life: Scientists have some basic speculations about the origin of life and life, but they still have not been able to give a specific answer. How exactly life came into being has always been a mystery.

Geophysics: Geophysics in nature is a great mystery, which involves the internal structure and movement of the earth, as well as the external phenomena of the earth, such as **, volcanic eruptions, meteorite impacts, etc.
Geobiology: Geobiology is the science that studies the phenomena and life of life on Earth. It involves several fields such as biology, geology, geophysics, etc., allowing people to better understand life and ecosystems on Earth.
Space Science: Space science is a big mystery that involves many fields such as astronomy, space technology, and astrophysics. People can observe and study celestial bodies and phenomena in space, such as stars, planets, satellites, comets, etc., as well as the environment and phenomena in space, such as space radiation, space junk, etc.
These mysteries show the wonder and mystery of nature, and also provide important clues and directions for human exploration of nature and science.
