paragraph on water conversion in 150 words
Answers
Answer:
Water is transferred from the surface to the atmosphere through evaporation, the process by which water changes from a liquid to a gas.
Approximately 80% of all evaporation is from the oceans, with the remaining 20% coming from inland water and vegetation. Winds transport the evaporated water around the globe, influencing the humidity of the air throughout the world. For example, a typical hot and humid summer day in the Midwestern United States is caused by winds blowing tropical oceanic air northward from the Gulf of Mexico.

Most evaporated water exists as a gas outside of clouds and evaporation is more intense in the presence of warmer temperatures. This is shown in the image above, where the strongest evaporation was occurring over the oceans and near the equator (indicated by shades of red and yellow).
Answer:
It is said that around 3.7 billion years ago, the earth cooled down and had warm oceans. In these warm water bodies, the first single-celled organisms evolved. Thus, water was instrumental in the origin of life.
70% of the earth is covered with water, and up to 70% of the human body is made of water. Today we have millions of marine species, but many plants and animals evolved to survive in non-saline conditions.
The human civilization rose on the banks of rivers. Early human beings settled down along the fertile river basins as it was easy for growing crops, and was convenient for transportation too.
Presently, agriculture demands for 70% of the freshwater needs. Industries and domestic uses share the rest thirty percent. But this precious resource has become scarce due to many human-made reasons.
