Why does it rain?。。。。。 said

1.Because the moisture on the surface of the earth will evaporate in the air after being heated, so that there will be more and more moisture in the air, and then it is the action of dust in the air, and the water vapor will condense together when it encounters dust, and it will fall down when it can not be suspended, and finally form rain.

2.Because you're sad.

For the Earth's atmospheric circulation.

Because the sky has times when it's sad, just like you cry when you're sad.

Because there are problem children like you.

Because the heavens are sad at times.

It's raining a lot over there, so you seem to be helpless to ask this question.

Evaporation of water vapor can occur at any time, but not rain all the time. In the air, when the temperature is high, the amount of water vapor that can be held is large, and when the temperature is low, the amount of water vapor that can be held in the air is less. When the air moves from high temperature to low temperature, the water vapor will change from unsaturated to supersaturated, and then the water vapor will condense into water droplets, and when the weight of the water droplets exceeds the buoyancy of the air, rain will fall.

For example, in the afternoon of summer, due to the strong water vapor evaporation, rise, condensation, and form showers; Frontal rain formed by the southward movement of cold air and the hot and humid air flow from the southeast, and so on.

As rivers, rivers, lakes, and seas are exposed to the sun, water becomes water vapor. The water vapor rises and turns into small water droplets or Xiaoice crystals, and the air flow below is constantly transporting the water vapor to the clouds. The small water droplets and Xiaoice crystals in the cloud collide with each other in motion, and the volume will increase.

The water droplets in the lower layer of the cloud slowly get larger, and as the volume of the ice crystals in the upper layer of the cloud increases, the water droplets fall between the droplets in the lower part of the cloud, and the water droplets become larger and larger. When these droplets are so big that the updrafts can't hold them back, it rains.

The sun evaporates the water on the earth, and the water forms clouds as vapor, and when the clouds can't bear too much steam, they naturally fall into rain, which is just a process of physical change.

I cried because I was moved

That's like why are you eating?

I don't know about this, I'll go up and ask you in a few days.

It's like why my mother wants to get married.

Sunrise and sunset, wind and thunder, purely natural phenomenon, since it has become a law, there is no need to drill the tip of the horns, then I can only say that because it is going to rain, it will rain.

For if there is much rain in the sky, it will weigh the heavens greatly.

In order to alleviate the congestion in the sky, they have reached an agreement with each other to take the initiative to skydive at the bottom.

That's a human problem. Ha ha.

The reason why it rains is because of water vapor. A certain temperature will cause the water on the ground to form vapor and rise into the air, and when it accumulates to a certain extent, it will encounter cold air in the air, which will cause the water vapor to form water and fall to the ground, which is what we call rain. If the temperature on the ground is not high, strong cold air in the air will bloom and snowflakes will fall.

If the ground temperature is high, the air encounters strong cold air convection, and hail will form and fall.

There is generally no money in the sky, but there is also a phenomenon of money, which is caused by the tornado hitting the vault and blowing the money from this place to other places, not falling from the sky out of thin air. In our country, there was a spectacle of paying money in the Qing Dynasty.

We all know it's going to rain. Whenever we see a bird flying low, every time a fish floats, I know it's going to rain. After a while, it got dark and it started to rain.

Why does it rain in the sky, the rain is the water on the ground that turns into water vapor and floats into the clouds, and the water vapor in the clouds accumulates more and more, and when it encounters cold air, it becomes rain or hail or snow falls. In this way, we saw rain and snow!

God drank too much water. Put it out.

God, drink too much water.

Because it's going to rain, it's going to rain.

The weather is hot, and the water evaporates and accumulates into the sky to form clouds. Ice crystals accumulate and gradually increase in volume, and the cloud buoyancy cannot support the ice crystals, and the ice crystals fall and gradually melt and finally form water. It's a natural law.

As rivers, rivers, lakes, and seas are exposed to the sun, water becomes water vapor. The water vapor rises and turns into small droplets, and finally into clouds. The small water droplets or Xiaoice crystals that make up the cloud are supported by the air flow below, and the rising air flow is constantly transporting the water vapor below the cloud to the cloud.

The small water droplets and Xiaoice crystals in the cloud collide with each other in motion, and the volume will increase. The water droplets in the lower layer of the cloud gradually become larger, and as the volume of the ice crystals in the upper layer of the cloud increases, the water droplets fall between the droplets in the lower part of the cloud layer, and the water droplets become larger and larger. When these droplets are so big that the updrafts can't hold them, it rains.

Countless bubbles in the ocean are constantly appearing in the form of waves, and water molecules are constantly spraying into the sky. These molecules, which are rich in salt, are transported from the atmosphere by wind.

Pushing upwards, the water vapor rising from the ocean gathers in the form of water droplets and ice crystals to form clouds. Clouds are made up of water vapor that collects around ice crystals or soot in the air.

Qi formed. Since the water droplets in it are small (millimeters in diameter), they are suspended and scattered in the air. In this way, the sky is covered with clouds. In the ice crystals and.

Tiny water droplets that gather around the smoke form raindrops. In this way, water droplets that exceed the weight of the air leave the cloud and fall in the form of rain.

Scientists who study cloud patterns have come to a surprising conclusion about the formation of rain. Nimbus clouds form as one of the cumulonimbus clouds in a certain system and stage.

The formative stages of scientific research are as follows:

The first stage, movement: the cloud is driven by the wind at its location, i.e., moving.

The second stage, unionization: these small patches of clouds, propelled by the wind, unite in a certain area to form a new, larger cloud.

Stage 3, Accumulation: After the small cloud patches unite, the upward gravitational pull within the large cloud mass increases. The upward gravitational pull at the center of the cloud is stronger than the gravitational pull at the periphery. These are up.

The gravitational pull causes the cloud to expand vertically. In this way, the clouds expand upwards and converge one by one. At the same time, the cloud body is extended to a relatively low temperature.

Extend. As a result, the water droplets and hail particles on the cloud begin to increase. After the above phases, the water droplets and hail particles gain weight so that the upward gravitational pull cannot support them.

Eventually, it rains and hails from the clouds to the ground.
