Why is the amount of evaporation over the ocean greater than the amount of precipitation over the ocean?

Why is the amount of evaporation over the ocean greater than the amount of precipitation over the ocean?

The rate of evaporation exceeds the rate of precipitation over the oceans , which are therefore a net source of moisture; this moisture is then transported to the landmasses, which are a net sink for moisture, where precipitation exceeds evapotranspiration .

Is the amount of water on Earth increasing or decreasing?

Water flows endlessly between the ocean, atmosphere, and land. Earth’s water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.

Why is there more evaporation from the sea than from the 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.

What would happen if water didn’t exist?

With no water supply, all vegetation would soon die out and the world would resemble a brownish dot, rather than a green and blue one. Clouds would cease to formulate and precipitation would stop as a necessary consequence, meaning that the weather would be dictated almost entirely by wind patterns

What would happen if water wasn’t polar?

The reason water is a liquid at room temperature is that the water molecules stick to each other with hydrogen bonds and make it difficult for any one water molecule to break free and evaporate (become a gas). If water was non-polar, it could not form hydrogen bonds and therefore would be a gas at room temperature.

What would happen if water disappeared in 100 words?

Answer Expert Verified All life (living) would die, if all the water from the earth, disappeared. The oceans would lie bare, covered by several inches to feet of salt. Water is a large component of all living cells, animals, plants etc and thus they would all be completely destroyed

What will happen if most of the fresh water on earth is finished?

If this happened, it wouldn’t take long for the common water supply to become unsanitary under these conditions. The polluted water supply would kill aquatic life, further reducing the available food supply. Water-borne diseases, such as diarrhea, would spread

What do you think happened to the water that disappeared in clothes?

When wet clothes are keep in the sunlight, Due to the sun’s hot rays, the molecules of water which present in the clothes gain energy and evaporates. So it becomes water vapour (gaseous form of water) and evaporates there by leaving the clothes. Hence the clothes get dry up

What kind of resources is the poet referring to?

the resources referred to by the poet is water. it is one of the most indispensable resources of life. it can be said to be one of the precondition of the life like air

How is a thing of beauty is a joy forever?

Ans: According to John Keats a thing of beauty is a joy of forever. It is a constant source of happiness and pleasure. Its loveliness increases every moment. It will never pass into nothingness

What is the endless fountain of immortal drink?

Complete answer: This endless fountain of the immortal drink is pouring from the heaven’s brink. In the poem, the poet gives the description of the beautiful things on earth and states that all these beautiful things are God’s gift to us which is pouring from heaven.

What is the theme of the central idea of the poem?

Theme is the lesson about life or statement about human nature that the poem expresses. To determine theme, start by figuring out the main idea. Then keep looking around the poem for details such as the structure, sounds, word choice, and any poetic devices

How do you find the central idea of a poem?

The central theme of a poem represents its controlling idea. This idea is crafted and developed throughout the poem and can be identified by assessing the poem’s rhythm, setting, tone, mood, diction and, occasionally, title.

What is the message of the poem Invictus?

Invictus is a poem which focuses on the human spirit and its ability to overcome adversity. It is a rallying cry for those who find themselves in dark and trying situations, who have to dig deep and fight for their lives. The poet certainly knew hard times and needed all his strength to battle against disease

What is the message of the road not taken?

The main theme of “The Road Not Taken” is that life is full of choices which will define our destinies. The speaker spends a while deliberating when he comes to a fork in the road, which symbolizes a choice he must make in his life

What is the message of the poem Death be not proud?

Lesson Summary Overall, John Donne’s poem ‘Death Be Not Proud’ is a masterful argument against the power of Death. The theme, or the message, of the poem is that Death is not some all-powerful being that humans should fear. Instead, Death is actually a slave to the human race and has no power over our souls

How is death treated in Donne’s poetry?

Most of John Donne’s works dealt with death directly or indirectly but death is an unimportant matter for him while others fear for death. He wanted to have superiority over the horrible face of death rather than being its slave and victim

Why is the amount of evaporation over the ocean greater than the amount of precipitation over the ocean?

The rate of evaporation exceeds the rate of precipitation over the oceans , which are therefore a net source of moisture; this moisture is then transported to the landmasses, which are a net sink for moisture, where precipitation exceeds evapotranspiration .

Why does pure water evaporate faster than seawater?

In the case of saltwater, you may have noticed that it evaporated a bit more slowly than pure water. This is because the water molecules are attracted to the dissolved salt ions and it requires more energy to break apart those water molecules for them to evaporate.

What happens to salt when water evaporates?

Show the animation: Evaporating Salt Water. The water molecules that evaporate become a gas called water vapor. Only the water evaporates, leaving the sodium and chloride ions behind. The sodium and chloride ions attract each other and re- form salt crystals.

How do you make water evaporate slower?

Cool the water down or limit its exposure to heat by keeping it in the shade, adding ice or cooling with refrigerated pipes. This lowers the kinetic energy available to the water molecules, which slows the evaporation rate.

What stops water from evaporating?

Chemical monolayers reduce evaporation by creating an insoluble film of a single layer of packed fatty alcohol molecules that acts as a physical barrier to water molecules escaping the surface (pores smaller than H2O) and a possible shield from air movements interacting with water surface molecules.

Does water evaporate more with lid on or off?

Cooking a soup, stew, or sauce uncovered allows water to evaporate, so if your goal is to reduce a sauce or thicken a soup, skip the lid. The longer you cook your dish, the more water that will evaporate and the thicker the liquid becomes—that means the flavors become more concentrated, too.

Does water evaporate faster in dry air?

Water evaporates faster if the temperature is higher, the air is dry, and if there’s wind. The lower the relative humidity, the drier the air, and the higher the evaporation rate. The more humid the air, the closer the air is to saturation, and less evaporation can occur.

How long does it take for a drop of water to evaporate at room temperature?

1.2 hours

Does water evaporate faster in hot weather?

Although water can evaporate at low temperatures, the rate of evaporation increases as the temperature increases. This makes sense because at higher temperatures, more molecules are moving faster; therefore, it is more likely for a molecule to have enough energy to break away from the liquid to become a gas.

Is the water still or moving?

Water, in its many forms, moves all over the Earth. Water vapor moves with the air currents, falling as rain from the clouds. Frozen glaciers creep slowly down from polar regions, then recede as they warm and melt.

At what temperature does water evaporate more rapidly?

212 degrees Fahrenheit

What 3 things can increase the rate of evaporation?

Factors That Affect the Rate of Evaporation

  • temperature of the liquid. A cup of hot water will evaporate more quickly than a cup of cold water.
  • exposed surface area of the liquid.
  • presence or absence of other substances in the liquid.
  • air movement.
  • concentration of the evaporating substance in the air.

How fast can water evaporate?

Scientists there found that the rate of evaporation can be below 76 centimeters (30 inches) per year at the low end, to 305 centimeters (120 inches) per year on the high end.

How quickly does acetone evaporate?

How long does it take for a drop of acetone to evaporate? Acetone evaporates rapidly, even from water and soil. Once in the atmosphere, it has a 22-day half-life and is degraded by UV light via photolysis (primarily into methane and ethane.)

Does acetone evaporate if left open?

Re: Acetone evaporation If the bottle is opened, then some of the acetone vapors will disperse and upset the equilibrium. As a result, more molecules can evaporate to balance the equilibrium. The evaporation takes energy from the liquid and the liquid temperature will fall.

Why does acetone evaporate so quickly?

Acetone has the weakest intermolecular forces, so it evaporated most quickly. Acetone does not participate in hydrogen bonding, so its intermolecular forces are comparatively weaker, and it evaporates most quickly.

Does acetone dissolve plastic bottles?

The Kind of Plastic There are all kinds of plastics. If a particular plastic bears a close enough similarity to acetone, the acetone will dissolve or at least affect its surface, softening, smearing or even dissolving the plastic. Other plastics, dissimilar to acetone, will remain unaffected by the solvent.

How do you slow down acetone evaporation?

The solvent strength makes acetone excellent for removing paints and finishes, so it is a common ingredient in paint and varnish removers. Evaporation is retarded by the inclusion of paraffin wax, which rises to the surface of thickly applied remover and forms a barrier.
