What causes water to evaporate from the ocean lakes and rivers?

What causes water to evaporate from the ocean lakes and rivers?

The water that falls as rain is constantly recycled because water can change from a liquid to a gas (a process known as evaporation) and back to a liquid again (condensation). The water from rivers, seas and oceans is turned into water vapour by the sun’s heat and by the wind.

Why does water evaporate from the ocean?

During the day, the sun heats up the air and ocean surface, causing water molecules to evaporate. Evaporation occurs when a liquid molecule of water escapes into the air as a gas. Over the ocean, evaporation appears to remain constant, both day and night. Water in the air in gas form is known as water vapor.

Why does most rain fall on the ocean and most water evaporate from it?

The rain that falls on land runs off into rivers and streams, or soaks into the ground. Eventually, most of it makes its way back to the oceans. Since the oceans contain about 97 percent of Earth’s surface water, they make the biggest contribution to evaporation.

Does water evaporate from plants rivers and oceans?

Water evaporates from within soils and through vegetation and from bodies of water (such as rivers, lakes and oceans). This evaporated water accumulates as water vapour in clouds and returns to the Earth as rain or snow.

What causes evaporation?

In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. When it is cool enough, the water vapor condenses and returns to liquid water.

Why don t the oceans simply reabsorb the water that evaporates?

because the oceans already have a ton of water in them so they don’t really need to absorb the water again that evaporates…

Why does the ocean not evaporate?

Why doesn’t 71% water of the earth dry or evaporate? The simple answer: Because it rains. The not so simple answer: By some estimates, the Earth has already lost about a quarter of its water, and it is predicted to lose almost all of its water in a billion or so years from now.

What happens when ocean water evaporates?

The water is evaporated into the air, forms or goes into clouds, and then returns in the form of precipitation. This is what is called the water cycle. When ocean saltwater evaporates, the salt in the water is left in the water. This causes the saltwater to become heavily laden with salt.

How much water evaporates from the ocean each day?

This gives us a total of 496,000 cubic kilometers of water evaporated/transpirated from the oceans and continents per year. To answer your question, roughly 1400 cubic kilometers (1.4 x 10^15 liters) of water is evaporated each day on earth.

What is evaporation explain it?

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.

Why does more water evaporate off oceans than on land?

After all, the large surface area of the oceans (over 70 percent of the Earth’s surface is covered by the oceans) provides the opportunity for large-scale evaporation to occur. Evaporation is more prevalent over the oceans than precipitation, while over the land, precipitation routinely exceeds evaporation.

How does the ocean lose water to the air?

The ocean loses water to the air when the water evaporates and turns into water vapor (steam). The winds in the atmosphere mix up the water vapor over the land and ocean, so that there is a net movement of water from land to ocean of 37 trillion tons of water per year.

What happens to the water that evaporates from the oceans?

Most of the water that evaporates from the oceans falls back into the oceans as precipitation. Only about 10 per cent of the water evaporated from the oceans is transported over land and falls as precipitation. Once evaporated, a water molecule spends about 10 days in the air.

Why does water become salty when it evaporates?

Water evaporates, but not the dissolved minerals that get in the water when it flows along the ground. When the water that is evaporated off is not replenished by precipitation, the water becomes more and more salty as those minerals accumulate.

What happens to the water in lakes during summer?

Even though the surface continues to warm all summer, the less dense water still stays on top of the lake. Even in summer the bottom half of the lake still stays almost as cold as it was in winter. During summer, the less dense warmer water stays on top of the colder water; no mixing of water occurs.

Why don’t lakes and bodies of water evaporate?

There are two main reasons for this: first, the amount of water present in lakes and large water bodies is huge (at least compared to what you might have in a beaker/tub). Therefore, the process of evaporation is quite slow, which is why you don’t notice the difference in their water levels.
