Water, a kind of molecule that was formed by one hydrogen atom with two oxygen atoms that was tied covalently. Water cover around 3/4 part of the world. Its said as the source of life because almost all organisms need it to live.

Water can be found almost everywhere. It can be found from lakes, rivers, seas, etc. This water can be found in different form based on the climate and season where the water found. It can be solid in low temperature under 0 degree celcious which called ice, liquid in temperature between 0-100 degree celcious which called water, and vapor in high temperature above 100 degree celcious. This vapor called water vapor.

Water aren't constant only at one place. This is because water undergo long journey which usually called "water cycle". This cycle start with water evaporation on Earth that was caused by the Sun warm. Then, this water vapor go up until reach Troposphere Layer and acumulated, then form cloud. More water that was evaporated by the sun warm, the bigger the cloud. Thats why there're only a little cloud at the morning time due the little amount of water that was evaporated.

After the cloud formation, many particles that were come from seas and oceans are brought to the Troposphere layer and together with the temperature, condense the cloud back into water and fall back to Earth as rain. This rainfall amount is same with the water amount that was evaporate. This amount are always same because if the amount aren't same, this world will be a dead planet due the unbalance of the environment.

After fall back to Earth as rain, this water will infiltrate into the soil and undergo a long journey to go back to the sea. After reach the sea, this water will undergo the water cycle again.
