What happens to a water molecule during the water cycle?
Whatever path, the water comes out of the atmosphere and makes it to the surface. Water moves from the ground or oceans into the atmosphere through a process called evaporation. It’s a process that happens on a molecular level when the molecules of water are really energized and rise into the air.
How does warm water affect the water cycle?
Climate change is likely causing parts of the water cycle to speed up as warming global temperatures increase the rate of evaporation worldwide. More evaporation is causing more precipitation, on average. Higher evaporation and precipitation rates are not evenly distributed around the world.
How does the water cycle affect lakes?
Lakes are valuable natural resources, both for human and non-human life. One part of the water cycle that is obviously essential to all life on Earth is the freshwater existing on the land surface. Outflows from lakes and rivers include evaporation, movement of water into groundwater, and withdrawals by people.
How long does a water molecule stay in a lake?
Storage in the water cycle
| Reservoir | Estimated residence time |
|---|---|
| Groundwater | months–10,000 years |
| Glaciers | 40–400 years |
| Lake | 100 years |
| Ocean | 3,000–3,500 years |
What happens to water during the water cycle?
As it moves through the water cycle, water often changes from a liquid, to a solid (ice), to a gas (water vapor). Water in oceans and lakes is typically liquid; but it is solid ice in glaciers, and often invisible water vapor in the atmosphere. Clouds are tiny droplets of liquid water or small ice crystals.
Why is the water cycle important to all animals?
The water cycle is critical to all animals and life on Earth. All animals need to take in water, use it, and get rid of the excess—animals have their own mini-water cycle going all the time. And some, like this parrot, have even learned to use a park drinking fountain when they need a drink.
How is latent heat obtained in the water cycle?
Latent heat is heat obtained by water molecules as they transition from liquid or solid to vapor; the heat is released when the molecules condense from vapor back to liquid or solid form, creating cloud droplets and various forms of precipitation. Water vapor—and with it energy—is carried around the globe by weather systems.
How does groundwater contribute to the water cycle?
As part of the water cycle, groundwater is a major contributor to flow in many streams and rivers and has a strong influence on river and wetland habitats for plants and animals. People have been using groundwater for thousands of years and continue to use it today, largely for drinking water and irrigation.
