Heat energy becomes gravitational potential energy.
The information in the encyclopedia is good, and it is copied for the reference of the landlord.
When 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 growth 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.

The process by which water turns into water vapor is called evaporation, and the phenomenon of water vapor turning into water is called condensation or liquefaction.
The vaporization process that occurs on the surface of the liquid when the temperature of the liquid is below the boiling point can occur at any temperature. Factors that affect the speed of evaporation: temperature, humidity, surface area of the liquid, air flow on the surface of the liquid, etc.
The amount of evaporation is usually expressed in millimeters of the thickness of the water layer that has been evaporated. In addition to denoting a physical phenomenon, "evaporation" is also called "evaporation" by its original meaning through association.
Condensation is the cooling of a gas into a liquid, such as water vapor when it is cooled into water. The lower the temperature, the faster the condensation. Its reverse process is called evaporation. Condensation is one of the liquefied forms, but it is not exactly the same as liquefaction.
Precautions. 1. The average distance between molecules in a liquid is much smaller than that in a gas. During vaporization, the average distance of molecules increases and the volume increases sharply, and it is necessary to overcome the gravitational force between molecules and resist the atmospheric pressure. Therefore, vaporization is endothermic.
The heat absorbed by a unit mass of liquid when it is transformed into vapor at the same temperature is called the latent heat of vaporization, or heat of vaporization for short.
The heat of vaporization decreases with increasing temperature because the liquid molecules have greater kinetic energy at higher temperatures, and the difference between the liquid and gas phases decreases. At the critical temperature, the substance is in a critical state, the difference between the gas phase and the liquid phase disappears, and the heat of vaporization is zero. Vaporization has two forms: evaporation and boiling.
2. Liquefied exothermy.
1) A 100 scald with water vapor tends to be much more severe than a 100 scald with boiling water – a large amount of heat is released when the water vapor liquefies.
2) Hand breath in winter - the water vapor in the mouth liquefies and exothermics to warm the hands.

Summary. In the water cycle, the water vapor of the clouds formed is the water vapor that evaporates from the earth and the water vapor that is in the air.
In the water cycle, the water vapor of the clouds formed comes from ** respectively.
In the water cycle, the water vapor of the clouds formed is the water vapor that evaporates from the earth and the water vapor that is in the air.
What does the surface runoff formed by rainfall produce to the surface during the flow process.
The surface runoff formed by rainfall has an erosive and transport effect on the surface during the flow process.
Erosion causes soil erosion in some of the ground protrusions, while sedimentation fills in some of the low-lying areas, creating different topographic structures on Earth.
The phenomenon of moisture in the atmosphere being transported from one region to another with the air flow is.
The transport of moisture from the atmosphere from one region to another is a link in the hydrological cycle.
There are two types of water vapor transport, horizontal transport is mainly to bring water vapor from the ocean to land, which is the main form of water vapor transport.
Vertical transport is the upward movement of air that transports water vapor from the lower levels to the upper levels to form clouds that cause rainfall.

Poor on the third night of the first month of September, the dew is like a pearl and the moon is like a bow, and we can see the dew on the autumn night because: it is because in autumn, the sun has a shorter sunshine time and the weather gradually cools, and the hot air of the southeast ocean is gradually replaced by the cold air of the north, and the temperature difference between day and night is large.
As a result, the water vapor is cooled and liquefied to form dewdrops.

Water stuffy thick limbs - water vapor.
Clouds - water droplets - rain.
The specific process is as follows:
Water – heated – turned into water vapor – floated in the air, turned into clouds – condensed into small droplets – small droplets gathered more and more – became rain or snow falling.
The vaporization of water from liquid to gaseous state is called endothermic process, and solidification to solid state is an exothermic process.
The melting of water from the solid state to the liquid state is called an endothermic process, and the sublimation to the gaseous state is an endothermic process.
Liquefaction of water from gaseous to liquid state is an exothermic process, and condensation to solid state is an exothermic process.

Clouds are small water droplets or Xiaoice crystals formed by the liquefaction of water vapor in the atmosphere when cold, and the mixture is a visible polymer floating in the air.
Clouds are the tangible result of the vast water cycle on Earth. When the sun shines on the Earth's surface, the water evaporates to form water vapor, and once the water vapor is supersaturated, water molecules collect around the dust (condensation nuclei) in the air, and the resulting water droplets or ice crystals scatter sunlight in all directions, which gives the appearance of clouds.

Summary. Generally, water evaporates from the ocean to form clouds above, and the rest is generally rain, because clouds are basically very small rain particles, and then clouds are formed, when the temperature in the clouds decreases, then the water vapor condenses to form water droplets, and then the clouds cannot bear the weight, and then it will fall and form rain.
When water evaporates from the ocean and rises to form clouds, what is left?
Your question has been seen and is being answered for you, please wait. I am a special guest of the sedan chair, and I am good at answering various questions about the field of education, and I am happy to serve you
Generally, water evaporates from the ocean to form clouds above, and the rest of the shed skin is generally rain, because the clouds are basically very small rain particles, and then the clouds are formed, when the temperature in the clouds decreases, then the water vapor condenses to form water droplets, and then the clouds do not bear the weight of carelessness, and the rock and foundation will then fall to form rainfall.
He usually doesn't leave the town to do anything else, because if it evaporates, it is basically water vapor, and after evaporation, the minerals and a small amount of micro-royal creatures in it are carried into the air with the rise of water vapor.

There are often white clouds floating in the sky, these white clouds are formed by water vapor, and when it is cold, it will form water droplets or snowflakes, hail, etc. to fall, which shows that clouds also have its weight, some people calculate that a cubic kilometer of clouds contains about 500 tons of water vapor, and it is obvious that the clouds are denser than the air.
From the ground, a cubic kilometer of clouds is not very large, because the height of the clouds is more than 1,000 meters, and some clouds are even more than 5,000 meters. And when cloudy weather appears, such clouds can be said to abound, it can be said that as far as the eye can see, millions of tons of clouds are floating in the sky, why don't clouds of such weight fall? Why do you have to turn into raindrops, snowflakes or hail before they fall to the ground?
In fact, the main reason is that the water vapor particles in the clouds are too small, and the calculation finds that the raindrops with a diameter of about one centimeter fall at a speed of about one meter per second without wind in the air, and the raindrops of drizzle with a diameter of about 1 millimeter fall at a speed of one meter per second without wind in the air, and the speed of the small fog-like water droplets with a diameter of about one millimeter is only about 1 centimeter per second without wind.
Most of the water vapor in the clouds are small fog-like water droplets, some of which are Xiaoice crystals of the same size, and it stands to reason that they will also fall to the ground in a windless state, but due to the transpiration of the ground and the influence of wind, the clouds will not sink to the ground, because the temperature of the earth is higher on the surface, and the temperature in the air is lower.
<> However, when the rainfall conditions appear, the fog-like small water droplets in the clouds will become larger and larger under the collision with each other, thus forming larger raindrops, and they can overcome the evapotranspiration of the air and fall to the ground, if the temperature in the air is particularly low, these small water droplets will become snowflakes and hail, the weight of snowflakes is lighter, the surface area is larger, so the speed of landing is relatively slow, and the weight of hail is larger, and the speed of landing is relatively fast.
-
Because the Earth's gravitational pull is so strong that it attracts water vapor, and the Sun is so far away from the Earth, the Sun doesn't let the clouds disappear.
-
In the upper air, the temperature is relatively low, so the water vapor condenses into small water droplets to form clouds, and the temperature of the sunlight is not enough for these water vapors to evaporate completely. So the clouds don't go away.
-
Because the accumulation of water vapor in the air is affected by the earth's gravity and does not fly into space, it can only float in a specific area where its mass can be separated from the ground, and the solar heat energy cannot ignite the water molecules in the air, so it can only float and accumulate because of the decline in gravity.

When the temperature of water exceeds 100 degrees Celsius (or above the boiling point), the water molecules absorb enough internal energy to convert it into a repulsive force that breaks free from the constraints of the molecules, and the distance between the molecules begins to increase, and the water changes from liquid to gaseous water. This gaseous water does not contain any other substances and is theoretically distilled water (the air contains impurities) also known as water vapor.
When water is below the boiling point, water can also slowly evaporate into water vapor.
Scientifically speaking, at room temperature, water will slowly turn into water vapor and fly into the air, this phenomenon is called evaporation. The water on the earth became water vapor, and these water vapors formed white clouds in the sky; If the water vapor condenses into larger water droplets, the water droplets will fall down to form rain.
In this layer of the atmosphere more than ten kilometers from the ground, the closer to the ground, the higher the temperature and the denser the air; The higher you go, the cooler the temperature and the thinner the air.
On the other hand, the water surface of rivers, lakes and seas, as well as the water of soil, animals and plants, evaporates into the air at any time and becomes water vapor. When water vapour enters the atmosphere, it becomes clouds that cause rain, or condenses into frost and dew, and then returns to the ground, seeping into the soil or flowing into rivers, lakes and seas. Later, it evaporates (vaporizes) again, and then condenses (condensation) and declines.
The cycle goes on and on.
After the water vapor enters the lower atmosphere from the evaporation surface, the temperature here is high, and the water vapor contained is more, and if this hot and humid air is lifted, the temperature will gradually decrease, and at a certain height, the water vapor in the air will reach saturation. If the air continues to be lifted, excess water vapor will be precipitated. If the temperature there is higher than 0°C, the excess water vapor condenses into small droplets; If the temperature is below 0 °C, the excess water vapor condenses into Xiaoice crystals.
When these small water droplets and Xiaoice crystals gradually increase to the point where the human eye can recognize them, they are clouds.
It is common to see that the sky is sometimes cloudless, sometimes cloudy, and sometimes cloudy. Why are there clouds in the sky and no clouds? How exactly are clouds formed? What is it made of?
Clouds floating in the sky are made up of many tiny water droplets or ice crystals, and some are made up of small water droplets or Xiaoice crystals mixed together. Sometimes it also contains some large raindrops, ice and snow particles, and the base of the cloud does not touch the ground and has a certain thickness.

You haven't studied chemistry, so you should have studied physics! In fact, it's just a physical thing.
The internal state changes, the water vaporizes into water vapor through cooling (exothermy) capacity, which is the so-called cloud, and the water vapor (cloud) liquefies into water when it encounters cold, and the water falls by gravity to form rainfall! Sometimes it will hail If you want to know the answer, you can + me first! Sissy.
