Anonymous users2024-02-12When water on Earth is irradiated by sunlight, it becomes water vapor and evaporates into the air. When water vapour meets cold air at high altitude, it condenses into small water droplets. These small droplets are small, with a diameter of only millimeters and a maximum of millimeters.
They are small and light, held in the air by updrafts in the air. It was these small droplets of water that gathered together in the air to form clouds. For these small droplets to fall to the ground as raindrops, they would have to increase in size by more than 1 million times.
How do these small droplets grow their size to more than 1 million times? It mainly relies on two means, one of which is condensation and condensation increase. The second is to rely on the collision and increase of cloud droplets.
In the early stages of raindrop formation, cloud droplets mainly rely on the continuous absorption of water vapor around the cloud body to condense and condense themselves. If the water and gas energy sources in the cloud are constantly replenished and the surface of the cloud droplets is often supersaturated, then this condensation process will continue, causing the cloud droplets to grow and become raindrops. However, sometimes the amount of water vapor in the cloud is limited, and in the same cloud, the water vapor is often in short supply, so that it is impossible to make each cloud drop increase into a larger raindrop, and some smaller cloud droplets have to be merged into the larger cloud droplets.
If water droplets and ice crystals coexist in the cloud, the process of condensation and bloom increase will be greatly accelerated. When the droplets in the cloud increase to a certain extent, due to the increasing size and weight of the large droplets, they will not only catch up with the slower small droplets in the process of descending, but will also "swallow" more small droplets and make themselves stronger. When the large cloud droplets grow larger and larger, and finally the air can no longer support them, they fall straight from the clouds to the ground, becoming our common rain.

Anonymous users2024-02-04It is absolutely not possible to fill the water with water, and the seedlings will die. What you should do is strengthen the cultivator, be sure to go a little deeper, and then water it with a small amount of water. In short, you should pay attention to diligent farming, not watering.

In addition to preventing soil-borne diseases through "antibacterial bacteria", the beneficial bacteria in biological fertilizer can also play a role in nitrogen fixation, phosphorus and potassium solving, and reducing salt damage.

If baking soda is excessive: Ca(OH)2+2NaHCO3==CaCO3 +Na2CO3+2H2O
If lime water is excessive: Ca(OH)2 + NaHCO3 == CaCO3 + NaOH + H2O

The universe is large**, and then the dust and materials in the universe accretion together due to gravity or collision to form countless planets, our earth is one of them, in addition, the sun, Venus, Mercury and other stars are the same. After the formation of the Earth, it was a hot planet and was still constantly receiving the impact of stars in the universe, and at that time, volcanic eruptions, thunder and lightning and other phenomena were frequent. The magma erupts from the ground and cools down to form the earth's crust ......After 4.6 billion years of evolution, the Earth is what it is today. >>>More
Thunder, also written as "靁" in ancient times, refers to the sound waves formed by the rapid expansion of the surrounding air and the impact of high energy released at the same time due to the passage of lightning, which is generally manifested as a rumbling sound accompanied by the lightning phenomenon. Because sound and light travel at different speeds in the atmosphere, one can determine the distance at which lightning occurs by calculating the time interval between them. In the air, the speed of sound is about 340 meters and seconds, so lightning occurs about every 3 seconds at a kilometer (or 5 seconds a mile). >>>More
The water vapor in the air is condensed into small water spots or Xiaoice crystals at high altitude, and the small water spots or Xiaoice crystals collide and merge with each other, becoming larger and larger, and when the air cannot support it, it will fall, and when the low-altitude temperature is higher than O, it is rain. >>>More
Tsunamis are usually caused by the seafloor with an epicenter within 50 km below the seafloor and above the Richter scale. The wavelength of the tsunami is larger than the maximum depth of the ocean, and the propagation near the seabed is not much hindered, regardless of the depth of the ocean, the wave can propagate past, the tsunami propagation speed in the ocean is about 500 to 1,000 kilometers per hour, and the distance between the two adjacent waves may also be as far as 500 to 650 kilometers, when the tsunami wave enters the land shed, due to the shallow depth, the wave height suddenly increases, and the waves rolled up by its wave movement can reach tens of meters high, and form a "water wall". >>>More
