  • There would be no human or animal life on earth except what could live in the oceans.
  • There would be no rain, so there would be
  • no crops, no rice, no wheat, no vegetables
  • no animals to eat except fish
  • no trees
  • no rivers
  • no drinking water except existing lakes

Then rain will stop coming down, all plants and trees will die, which means photosynthesis will stop, and all of the oxygen will eventually be replaced with carbon dioxide, which will kill all beings that breathe oxygen. The earth would survive, but very different from today.

It would end. All water would freeze.

The sun is the energy that makes the water cycle do what it does. So if there was no sun the water cycle wouldn't work..

With no Sun there would have been no Solar System hence no Earth, let alone any water to evaporate etc.

Water requires relatively more heat to raise it's temperature than most substances due to hydrogen bonds. It is important because plants have no way of regulating their temperature. Biochemical processes are temperature sensitive and can be destroyed at high temperatures. A medium that resists changes in temperature becomes very important.

There are three parts to thee water cycle: evaporation, condensation, and precipitation. The only part that requires the sun is evaporation. If there was no sun, none of the water in the oceans, rivers, or lakes would evaporate. This would break the the cycle and stop clouds from forming from condensation. If there are no clouds, it can't rain. So all the water would just stay where it was.

It would end. All water would freeze.

The sun is the energy that makes the water cycle do what it does. So if there was no sun the water cycle wouldn't work..

You've missed something rather more fundamental.

With no Sun there would be no Solar System hence no Earth. (The - or any - Solar System relies on a central star to act as accretion centre and hold it all together.)

Earth would become an ice-planet, warmed only by the heat remaining in the core. Any surface water is likely to turn to ice.

There would be no water cycle, all water would be frozen in a many mile thick layer over the entire earth forever.

What is the source of enegry in the water cycle?

The source of energy that causes the water cycle to happen is the sun. Without the sun water would not evaporate and then it would not condense. If there is no water condensed into clouds then there wouldn't be any rain or precipitation.

Without heat from the sun the water cycle would not work .


What would happen to the water cycle if the sun heated the atmosphere evenly?

If the sun heated the atmosphere evenly, the water vapor in the air wouldn't move from 1 place to another.


Is the sun the most important in the water cycle?

The sun is so critical to the water cycle because if their was no sun there would be no evaporation and the whole Water Cycle would collapse. It also is important because maybe there would be no more water in our life.


What would happen to Earth's hydrological cycle if the evaporation of water suddeny stopped?

A more relevant question would be what would happen to Earth's hydrological cycle if precipitation stopped. For there to be no more evaporation, our sun would have to die. If the Sun died, so would all plant and animal life...eventually...including us.


What would happen if the sun were to disapper?

if the sun would vanish the temperatures on the earth would drop drastically the oceans may get frozen . The plants would not be able to prepare food by the process of photosynthesis . the water cycle would not happen ultimately it would lead to mankind being destroyed


What is the water cycle powered by?

The Water cycle is powered by the sun.


How does the sun control the water cycle on earth?

The sun begins the water cycle by evaporating the water in seas and/or oceans.


What supplies the energy in water cycle?

The sun. The sun's energy comes in the form of heat. This begins the cycle with evaporation.


Why the sun is important to the water cycle?

the sun is important to the water cycle because without the sun the water wont evaporate.
