Question

What is the source of the water cycle?

Answer 1

Hint: The amount of water on Earth is very unusual. Water is essential for life on Earth and aids in the integration of the planet's lands, oceans, and atmosphere into a single system. The hydrological cycle - a never-ending worldwide process of water movement from clouds to land, to the ocean, and back to clouds - includes precipitation, evaporation, freezing and melting, and condensation.

Complete answer:
There are three main steps in the water cycle: i) Evaporation: primarily from the ocean's surface, but also from the surface of other bodies of water, as well as from plants.
ii) Condensation: Clouds are formed by condensation.
iii) Precipitation: Rain is caused by precipitation.

Evaporation from the oceans is the primary source of water in the water cycle. When rain falls, some of it will flow on the land surface (runoff), while others will be absorbed by vegetation, and finally, some will percolate underground (infiltration) to fill aquifers, resulting in springs feeding rivers.

Water will be returned to the oceans via runoff and rivers, where it will evaporate and return to the atmosphere. During evaporation, vegetation will return some of the water to the atmosphere as water vapour. The cycle has come to an end.

Water is an important natural resource that can be found in various forms throughout the environment. It is critical to comprehend how water moves through the ecosystem in order to effectively control it. Fresh water is limited and at risk. One of the most critical natural resource concerns facing humanity is the provision of sufficient clean, fresh water.

Due to rising population, economic expansion, and climate change, water scarcity is becoming a global issue. A shortage of clean, fresh water can stymie efforts to eliminate poverty and advance national development, leading to poor health, low productivity, food insecurity, and limited economic growth.
