How is the rain in the sky formed and why?

Rain is a natural phenomenon.

Water droplets falling from clouds. Water on land and ocean surfaces evaporates into water vapor.

The water vapor rises to a certain height and then condenses into small water droplets. These small droplets make up the clouds, which collide with each other in the clouds and merge into larger droplets. When it becomes too big for the air to hold, it falls from the clouds, forming rain.

<> water absorbs heat and becomes steam on the ground, rises to the upper steam in the sky, due to the low temperature of the upper steam, the volume of water vapor decreases and the proportion increases, the steam falls, because the following is high temperature steam, it falls again in the process of absorbing heat, and when it rises, it encounters low temperature and falls again, so the gas molecules gradually shrink, and finally concentrate at the bottom of the vapor layer, forming a low temperature zone below, and the cloud is formed with the concentration of water vapor to the cold area. As the cloud grows, the convection inside the cloud becomes more intense, the temperature gets cooler and lower, and finally raindrops form.

Why does it rain in the sky, rain is the water droplets that fall from the clouds, the water on the surface of the land and the sea evaporates into water vapor, the water vapor rises to a certain height and becomes water droplets when it is cold, these water droplets form clouds, they collide with each other in the clouds, merge into a large one, and when it is big enough to hold it, the air goes down from the clouds and forms rain.

When rivers, lakes, and oceans are illuminated by the sun, the water turns into steam. The water vapor rises, changes into small water droplets, and finally into clouds. The small water droplets and ice crystals that make up the clouds collide with each other as they move, increasing in size.

The water droplets in the lower layers of the clouds are getting larger and larger, while as the ice crystals in the upper layers of the clouds are getting bigger and bigger, they fall between the droplets in the lower layers of the clouds. When these water droplets become too large for the updraft to contain, it rains.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if there are any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, the like is the biggest help to me, thank you.

Due to the water vapor on the surface of the land and sea, it is constantly evaporating, and the needle holder keeps rising, and then it will condense into small water droplets, and when the small water droplets become larger, they will fall from the clouds, and then they will become rain. Because water has to absorb heat and turn into water vapor, when it rises into the air, the volume will shrink, and in the process of absorbing heat, it will fall, and the gas molecules will gradually become smaller, and then the temperature will drop, and the water vapor will condense into small water droplets, and when the weight of the small water droplets becomes larger, it will fall and become rain.

This is mainly due to the evaporation of the surface of the land and the sea, which forms water vapor, which rises to a certain height and becomes water droplets, which then collide in the clouds, thus forming the rain falling. Because this is a natural phenomenon, mainly because it is affected by the atmospheric circulation.

This is because there is a lot of water in the air, which then condenses into small droplets and lands, which is caused by low temperatures.

We already know that clouds are made up of many small water droplets and Xiaoice crystals, and that raindrops and snowflakes grow and grow larger. So, how do small water droplets and Xiaoice crystals grow and grow in the cloud? In a water cloud, the cloud droplets are all small droplets.

They are mainly increased by continuing to condense and colliding with each other. Therefore, in a water cloud, for the cloud droplet to increase to the size of a raindrop, the cloud first needs to be very thick, dense, and watery, so that it can continue to condense and grow; Secondly, there needs to be a strong vertical motion in the water cloud, so as to increase the chance of multiple collisions and merging. In the thinner and more stable water clouds, the cloud droplets do not have enough opportunity to condense and merge and grow, and can only cause cloudy, cloudy skies, and little rain.

The water on the surface of the land and sea evaporates into water vapor, and the water vapor rises to a certain height and becomes small water droplets when it is cold, and these small water droplets form clouds, which collide with each other in the clouds and merge into large water droplets, and when it is too large for the air to support, it falls from the clouds and forms rain.

Rain is the water droplets that fall from the clouds, the water on the surface of the land and the sea evaporates into water vapor, the water vapor rises to a certain height and becomes small water droplets when it is cold, these small water droplets make up the clouds, they collide with each other in the clouds, merge into large water droplets, and when it is too big for the air to support, it falls from the clouds and forms rain.

Rain is a natural precipitation phenomenon that is produced by disturbances in the atmospheric cycle, is an indispensable part of the Earth's water cycle, and is the only way for almost all terrestrial plants far from rivers to replenish fresh water. Raindrops fell from the sky, big and small, fast and slow. Rain is the most important source of fresh water in human life, and plants must also be nourished by rain and dew to thrive.

The main component of rainwater is water, there is a small amount of sulfur dioxide, nitrogen dioxide, usually the pH value of rainwater is about, the pH value is less than the rainwater is acid rain, in case of thunderstorms, rainwater will contain a small amount of ozone molecules, as well as a variety of impurities and floating dust in the air.

1. The small balls that fall from the sky are so transparent, so beautiful, and so round.

2. The summer rain is pure and warm, we all have to be a running child in the summer, although you have your favorite, even if the feet are muddy, we fall and get up, get up and fall again.

3. It sounds like a very crisp ball, ticking and ticking.

4. The light, crisp and beautiful balls are like a string of beautiful dreams, so complete, so free, so transparent, and so beautiful.

5. The raindrops are like pearls, sprinkled on the surface of the river, and the water surface is calm and unbridled.

Rain is produced by atmospheric circulatory disturbances. The specific formation process is as follows:

1. Water on the surface of land and sea evaporates into water vapor.

2. After the water vapor rises to a certain height, it turns into small water droplets when it is cold.

3. These small droplets form the cloud, and they collide with each other in the cloud and merge into large droplets.

4. When it is so big that the air can't hold it, it falls from the clouds and forms rain.

Water on Earth is irradiated by sunlight and evaporates into the air as water vapor. 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 the largest is only 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.

Rain is caused by the rise of moisture mixed with air impurities to form clouds, and as the mass increases, precipitation conditions are formed, and rain occurs.

Specifically, it can be understood as:

Clouds made up of liquid water droplets, including supercooled water droplets, are called hydrogenic clouds. If there are conditions for the cloud droplets to increase into raindrops and make the raindrops have a certain rate of decline, then it is rain or drizzle that falls. Clouds made up of ice crystals are called cryogenic clouds, while clouds that are made up of water droplets (mainly supercooled water droplets) and ice crystals together are called hybrid clouds.

Ice crystals or snowflakes that fall from ice-forming clouds or mixed clouds fall into the air layer above 0, and after melting, they also become raindrops that fall to the ground, forming rainfall.
