Knowledge or interesting phenomena about plants or weather.

The knowledge or interesting phenomena about plants and weather are as follows:

1. Japanese cherry blossoms are in full bloom: from March to April every year, Japanese cherry blossoms are in full bloom, which is a beautiful scenery. The flowering time and place of cherry blossoms are usually predicted in advance and attract thousands of tourists to watch.

2. The longest day in a year: the summer solstice, that is, June 20th or 2 1 day, is the longest day and the shortest night in a year. It is not only directly related to the orbit of the earth, but also related to the inclination angle of the earth's rotation.

3. Leaf color change: The color change of plant leaves can reflect different seasons and climatic conditions. In autumn, due to the decrease of temperature and sunshine, the leaves of plants will change from green to red or yellow, which is also called autumn color.

4. First Snow: In many places, the first snow is considered to be a very magical and romantic thing. The first snow usually appears one or two weeks before winter, which is a sign of the coming ice and snow season.

5. Drought in history: There have been many droughts in history, such as the three-year drought in China and the great famine in the United States. Drought will affect agriculture, economy and ecosystem to varying degrees, and it needs to be effectively dealt with.

6. Aurora: Aurora is a beautiful astronomical phenomenon, which usually appears in the Arctic and Antarctic regions. Aurora is formed by the release of energy between the magnetic field and charged particles when the solar wind hits the earth's magnetic field in the ionosphere.

7. Transformation: Plants convert light energy into chemical energy through photosynthesis, which is used for their own growth and reproduction, and is also the main source of oxygen on the earth. Plants are particularly important for the survival of human beings and animals.

8. Tornado: Tornado is a strong storm with a wind speed of 500 km/h, which is extremely destructive. Tornadoes often appear in tropical cyclones, storms and cold waves, causing serious losses to residents, houses and crops.

9. Desertification: Desertification is a serious global ecological problem. Under the influence of drought and excessive human activities, the land lost its productivity and eventually became a dry and barren desert. Desertification has brought a serious impact on the ecosystem and human life.

10, sea of clouds: The sea of clouds is an atmospheric phenomenon, which usually appears in some mountainous areas with complex terrain. Because the humid air cools and condenses when the mountain rises, it forms the fog formed by the clouds sinking into the valley, just like the ocean, so it is named the sea of clouds.
