Question

Почему вода в реках не кончается

Answer 1

Это происходит благодаря куруговороту воды в природе и её свойству текучести. Через атмосферу в мелкие  ручьи поступает влага (дожди, туманы, снег), но более важным источником явл. подземные воды нашей планеты.

Answer 2

Потому что реки питают другие реки (более маленькие), ручьи и т.п. Так же реки питают грунтовые воды.

Answer 3

Why doesn't water in rivers run out?

Water in rivers doesn't run out because of the water cycle, which is a continuous process that redistributes water on Earth. The water cycle involves the evaporation of water from bodies of water, such as rivers, lakes, and oceans, the condensation of water vapor into clouds, and the precipitation of water back onto the Earth's surface in the form of rain, snow, or other forms of precipitation. This continuous cycle ensures that water is constantly replenished in rivers and other bodies of water.

Evaporation: When the sun's heat causes water to evaporate from rivers, lakes, and oceans, it turns into water vapor and rises into the atmosphere.

Condensation: As the water vapor rises, it cools and condenses into tiny water droplets, forming clouds.

Precipitation: When the water droplets in the clouds become too heavy, they fall back to the Earth's surface as precipitation, which can include rain, snow, sleet, or hail.

Runoff: The precipitation that falls onto the Earth's surface flows into rivers, streams, and other bodies of water, replenishing them.

This continuous cycle ensures that water is constantly moving and being redistributed, preventing rivers from running out of water. Even if a river appears to have low water levels at certain times, it is likely due to factors such as seasonal variations, droughts, or human water usage, rather than the complete depletion of water in the river.

The water cycle is a natural process that has been occurring for billions of years, maintaining the Earth's water supply and sustaining life on our planet.
