Ask for an expository essay on rain, information about rain, and an introduction to rain

Write more information about rain, and then look for the whole text in a certain order. Appropriate descriptions of rain scenes can be inserted into the expository text, but not too much.

1. Rain is a natural precipitation phenomenon, which is produced by the disturbance of the atmospheric circulation, and is the earth's water cycle.

An indispensable part 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. Water evaporates on the earth's surface, rises and cools to form rain. Rain is the most important source of freshwater resources for human life.

2. Water droplets from the clouds where rain falls, and water on the surface of the land and sea evaporates into water vapor.

After the water vapor rises to a certain height, it becomes a small droplet of water when it is cold, and these small droplets form a cloud, which collides with each other in the cloud and merges into large droplets, and when it is so large that the air cannot hold it, it falls from the cloud and forms rain.

3. Rain is the most important freshwater resource in human life, and plants should also rely on the moisture of rain and dew to thrive. But flooding caused by heavy rains can also bring huge disasters to humans.

1. Perhaps, when winter comes, people will hate rain! But by this time, the rain has already made up, and it often turns into beautiful snowflakes that come to the world. Expression role:

Makeup", wrote the beauty and charm of the spring rain "Floating to the world" wrote the dynamic beauty of the spring rain, expressing the author's love for the winter rain.

2. "Water droplets drip from the buds, more delicate than a girl's tears." There always seems to be a silk curtain of transparent mist hanging in mid-air, pulling the colorful prism of the sun. ”

3. "The grass turns like a reviving earthworm, making a rustling sound that can only be heard in spring." "The use of analogy vividly shows us the spring scene after the rain;

4. "Rain, the rain of my love, you always flow in front of my eyes all year round, you bring vitality to my life, you bring nourishment to my feelings, and you bring flow to my thoughts." "The use of metaphor, personification, analogy and other techniques vividly shows us the love of rain.

Every tree seems to have opened its particularly bright eyes, and the arms of the branches are suddenly soft, and the germinating leaves are simply undulating with green waves" "Using anthropomorphic and figurative techniques, the whole tree, as well as each part of her, is personified and visualized, making it rich in human form as a whole, "bright eyes", "arms are suddenly soft", "germinating leaves are like waves of green shade", which replaces the vividness and image of the book, and also gives readers a different feeling.

6. Only in the rain did I truly feel that the world was alive, with joy and tears. Appreciation: Different life circumstances make it different to listen to the rain.

雨, a commonly used Chinese word pronounced yǔ or yù, was first seen in oracle bone inscriptions, where the word for rain resembles water droplets falling from the sky. The original meaning is the droplet of water falling to the ground in the clouds; The water droplets that fall from the clouds to the ground are extended to friends, which can also be compared to dispersion; It can also be used as a metaphor for grace, which moistens all things on the earth like rain; "Rain" in these senses is pronounced as yǔ. It is used as a verb in classical Chinese, referring to rainfall, pronounced yù; It is also used as a metaphor for falling like rain.

Rain is also a radical and is often used as a symbol.

In ancient characters, the horizontal image of rain is like the sky, and the vertical image is like raindrops. The word "rain" on the oracle bone inscription is like a horizontal sky; The dots on the bottom are like water droplets. Drops of water that fall from the sky are rain.

In the word "rain" in the small seal, "one" is like the sky, "冂" is like clouds, and "four points and one vertical part" is like water dripping from the sky between the clouds. The original meaning is the water droplets that descend from the clouds to the surface of the earth.

The Formation of Rain has long been a mystery to mankind, but following the invention of radar, the various stages of rain formation have been determined.

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 glaciated clouds, while clouds made up of water droplets (mainly supercooled water droplets) and ice crystal entrapments 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.

The stages of formation of cumulonimbus clouds, which are one of the rain clouds, in a certain system and stage, are scientifically studied 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 primer in the center of the cloud is stronger than the surrounding gravity.

These upward gravitational pulls cause the cloud to expand vertically. In this way, the clouds expanded upwards and converged one by one. At the same time, the cloud extends to places with relatively low temperature and dust differences.

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.
