Water is a common chemical substance that is essential for the survival of all known forms of life. In common usage, water refers only to its liquid form or state, but the substance also has a solid state, ice, and a gas state. state, water vapor or steam. About 1,460 petatons (Pt) (1,021 kilograms) of water cover 71% of the Earth's surface, mostly in oceans and other large bodies of water, with 1.6% of water underground in aquifers and 0.001 % in the air. in the form of vapor, clouds (formed by solid and liquid water particles suspended in the air), and precipitation.[1] and ponds 0.6% Some of Earth's water is contained in water towers, biological bodies, manufactured products, and food supplies.

How is water formed? English composition
States of water
solid, liquid, gas
Water exists in three different states: solid, liquid or
gaseous.
Clouds, snow and rain. are all made of some form of water
A cloud is made up of
tiny water droplets and/or ice crystals, a snowflake is an aggregate of several
ice crystals and rain is just liquid water.
Water existing as a gas is called water vapor.

Water can come from one kind of The shape changes to another. The heat of the sun causes water to evaporate in oceans, seas, rivers and lakes. Evaporation also takes heat from the ground and water from plants and animals. Formed by water vapor. This shape of clouds in the sky.
When dark clouds approached the mountain, they were forced up. As clouds rise, they cool. The higher they go, the cooler they get. This will cause more condensation of water vapor. As a result, the water tears in the clouds become bigger and bigger until they become heavy and fall to the ground and turn into rain.
Some of the rain falls to the ground and evaporates again. Part of it sinks to the ground. It can be used by thirsty plants. It can reach well or spring water. Most of the water returns to rivers,seas and oceans. Then the process started again. This process is called the water cycle.
The uses and functions of water English composition
WWater is very important to us. If you don't have water for three days, you will die. We can use water for flowers, for swimming, for washing and for many other things. We use it for cooking, generating electricity, putting out fires and many other things. and so on. We use millions of liters of water every day.
Do you know how water gets to your home? It circulates in water pipes. Some are long and wide, but others are short and narrow. Then the water goes through the water pipes to the tanks. It then passes through the water pipes to the river and to special plants (we call water plants) that purify the water. When the water is purified, we can drink it. don't leave any dicechets in the water we align with and keep the water clean.
Water is essential to living things. For example, if there is not enough water in a human body, a person may. feeling uncomfortable or getting sick easily. To make matters worse, you can die of thirst. Similarly, plants can wither or die from lack of water. Nations need water to stay alive.
Judging by the importance of water, we should know how to store it. The first thing is to stop polluting water, because what we really need is clean water. At the same time, be sure to turn off the tap immediately after using water. And we should use water efficiently to avoid wasting it. One way is to recycle as much water as possible. To summarize, we should save on water in order to maintain the abundance of water, which is an essential element for life.

.Water is very important for living beings. Without water, there can be no life on earth. All animals and plants need water.
Water is found almost everywhere. In some parts of the world there is water in the air.
As we have all discovered, water can be a solid, a liquid or a gas. When it is strong, it can be as hard as possible. brick, when it's a liquid, you can pour it out of a container when it's a ga.
Although about 70% of the Earth's surface is covered in water, many places in the world still lack water. So we should make good use of water. on earth

Water is almost everywhere. Even in the driest places in the world, there is water in the air.
Water, as you know, comes in solid, liquid and gaseous states. When solid, it can be as hard as a brick; when it is liquid, you can pour it out of a container; when it's gaseous, you can't see or smell it.
Although 70% of the Earth's surface is covered in water, many places around the world are still water-deficient. We must therefore make good use of water on earth. 2.
