Why are evaporation rates higher over the oceans than on land?

Why are evaporation rates higher over the oceans than on land?

Why are evaporation rates higher over the oceans than over land? 97% of the Earth’s water can be found in our oceans. More water = more potential evaporation. Evaporation depends on wind speed, temperature, and humidity which are all higher in the oceans than on land.

Where is ocean evaporation greatest?

In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area. Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents.

Is more water evaporated into the atmosphere from the oceans or from land?

Terms in this set (93) Globally, from which source does more water evaporate into the atmosphere, ocean or land? Ocean water evaporates to form gaseous water and moves into the atmosphere, where it condenses into liquid water and falls out of the atmosphere to land as rain.

Why does the ocean have most evaporation?

Evaporation from the oceans is the primary mechanism supporting the surface-to-atmosphere portion of the water cycle. 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.

What happens to the surface of the water when the rate of evaporation is greater?

A substance that has a larger surface area will evaporate faster, as there are more surface molecules per unit of volume that are potentially able to escape. the higher the temperature of the substance the greater the kinetic energy of the molecules at its surface and therefore the faster the rate of their evaporation.

Where does evaporation mostly occur?

Approximately 80% of all evaporation is from the oceans, with the remaining 20% coming from inland water and vegetation. Winds transport the evaporated water around the globe, influencing the humidity of the air throughout the world.

How does surface area affect evaporation?

Evaporation increases with an increase in the surface area If the surface area is increased, then the amount is of liquid that is exposed to air is larger. More molecules can escape with a wider surface area. For e.g. We spread out clothes to dry. We do that because that speeds up the process of vaporization.

Which is more common, precipitation or evaporation over land?

Evaporation is more prevalent over the oceans than precipitation, while over the land, precipitation routinely exceeds evaporation. Most of the water that evaporates from the oceans falls back into the oceans as precipitation. Only about 10 percent of the water evaporated from the oceans is transported over land and falls as precipitation.

Where does most of the evaporated water go?

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.

How to Calculate evaporation from the surface of the ocean?

To estimate evaporation from the surface of the World Ocean methods are applied which are based on the following formula: Е = ξ*u*(qS –q) (1) where qS –q – is specific humidity deficit calculated from the temperature of the water surface; u – is wind velocity; ξ – is parameter of evaporation.

Why is evaporation important to the production of fresh water?

Evaporation from the oceans is vital to the production of fresh water. Because more than 70 percent of the Earth’s surface is covered by oceans, they are the major source of water in the atmosphere. When that water evaporates, the salt is left behind. The fresh-water vapor then condenses into clouds,…
