What are the signs before it rains?
When the air pressure is low and the air humidity is high, the wings of insects will become heavy and unable to fly high because of the humidity. Swallows have to fly very low to catch them. Therefore, there is a folk saying that "the swallow flies low and it will rain".

3, small fish breathable: the fish in the pond suddenly floated to the surface of the water, as if inhaling in a big mouth. This means that it is going to rain. The reason is that fish need to absorb oxygen from the water, and when it rains, the air pressure is low, and the amount of air in the water decreases. The fish can't stand it, so they float.

4, puppy breathing: before it rains, the dog will shrink into a ball on the haystack and use its mouth as a heater.

5. Toads come out of the hole: because the skin is brittle, I am afraid of dryness. So in general, you can only see toads croaking at night. If it rains, they will go out to play in caves.

6. Earthworms on the road: Small earthworms live in wet places. If earthworms can come out to move, it means that the air is already wet. Pay attention to the rain at this time.

7, chickens do not enter the nest: chickens are afraid of heat because there are no sweat glands, especially before it rains in summer. If the chickens are driven into the nest, they still stay in the shade, which means it will rain heavily soon.

What are the wonderful phenomena in nature?

Aurora, solar eclipse, volcanic eruption, waterfall, fluorescent beach 1 and aurora are colorful luminous phenomena, which are produced by bright and beautiful glow at night when charged particles from the sun (solar wind) enter the earth's magnetic field. It is called the Southern Lights in Antarctica and the Northern Lights in the Arctic. Aurora is produced by the high-energy charged particle flow (solar wind) from the earth's magnetosphere or the sun exciting (or ionizing) molecules or atoms in the upper atmosphere. 2, eclipse eclipse, also known as eclipse, is the movement of the moon between the sun and the earth. If the three are in a straight line, the moon will block the light from the sun to the earth, and the shadow behind the moon will just fall on the earth. At this time, the eclipse happened. 3. Volcano eruption, a geological term, is a peculiar geological phenomenon, a manifestation of crustal movement, and the strongest display of heat energy inside the earth on the surface. It is the release of magma and other ejecta from the crater to the surface in a short time. Because the magma contains a large number of volatiles and the confining pressure of the overlying strata, these volatiles cannot overflow when dissolved in the magma. When the magma rises close to the surface, the pressure decreases and the volatiles are released sharply, thus forming a volcanic eruption. 4. Waterfall Waterfall is the water flowing from the place where the mountain wall or river bed suddenly falls. From a distance, it looks like a white cloth hanging. Geologically, it is called falling into the water, that is, when the river flows through faults, depressions and other areas, it falls vertically from the sky. Waterfalls are temporary features during the existence of rivers and will eventually disappear. 5. Fluorescent Beach "Fluorescent Beach", also known as "Mars Tide", is formed by luminous plankton. This phenomenon was accidentally discovered by Will Ho during his honeymoon trip in Maldives. 2065438+200565438+1On October 22nd, a blue fluorescent beach appeared in China, which was very spectacular.

What are the wonderful phenomena in nature (don't be too detailed

1, rainbow rainbow is formed by small water droplets in the sky. The role of water droplets is similar to that of prisms refracting natural light, forming various monochromatic lights in the sky, which is really amazing! However, due to the deterioration of environment and weather, rainbows become less and less common after rain. 2. Meteor shower Whenever some well-known comets orbit close to the earth, there will be meteor shower wonders on the earth, such as the Leonid meteor shower. First, the comet approaches the sun and is irradiated by high energy, evaporated, vaporized and shattered when it approaches the earth. Influenced by the gravity of the earth, comet fragments fell to the earth. When passing through the atmosphere, they glow and heat due to high-speed friction with the air, and countless comet fragments "meteor showers" fall from the ground. But most meteor showers burn in the atmosphere. 3. Lightning storm clouds usually generate charges, with negative charges at the bottom and positive charges at the top. They also generate positive charges on the ground and move with the clouds. Positive and negative charges attract each other, but air is not a good conductor. Positive charges rush to tree tops, hills, tall buildings and even above human bodies, trying to meet negatively charged clouds, while negatively charged dendritic tentacles extend downward and get closer to the ground. Finally, the positive and negative charges finally overcome the air barrier and connect. A huge current rushed from the ground to the clouds along the conductive path, producing a bright flash. The length of lightning may be only a few kilometers, but the longest can reach hundreds of kilometers. There are four suns in the sky at the same time. It is normal for four suns to appear in the sky at the same time. This is a physical phenomenon called "vacation". This kind of landscape can only be formed under specific climatic environment or meteorological conditions. Holidays appear in the sky because the temperature is low, the water vapor in the air is sufficient, and the water vapor condenses into ice crystals in the clouds. When ice crystals are refracted or reflected by sunlight, there will be a "holiday" phenomenon. There are many kinds of "holidays", some of which are ring-shaped and called halo. Some become light spots. The mysterious and veiled Shennongjia in China is located at the junction of Sichuan and Hubei between the Yangtze River and Hanshui River in China, and is known as the "Roof of Central China". It covers an area of 3,250 square kilometers, with forest land accounting for more than 85%. Average elevation1700m, highest point 3105m. There are many climate types. When it comes to Shennongjia, people can't help thinking of "savage". From ancient times to the present, a large number of records and legends about savages make it difficult to distinguish between true and false. From 1977 to 1980, the relevant departments organized two large-scale savage expeditions and collected a lot of evidence of the existence of savages, such as their hair, footprints and feces. And also found the bamboo nest where the savage lived. The results of the investigation seem to show that there is indeed a strange animal unknown to people in Shennongjia.
