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.
Where is the rate of evaporation faster?
Water evaporates faster if the temperature is higher, the air is dry, and if there’s wind. The same is true outside in the natural environment. Evaporation rates are generally higher in
hot, dry and windy climates
.
Which ocean has the highest evaporation rate?
The Red Sea
is the ocean basin that has the highest net evaporation [19], and provides large amounts of moisture that precipitate between the Gulf of Guinea and Indochina (JJA) and between the African Great Lakes and Asia (DJF).
How surface area affects evaporation?
Effect of the Surface area:
Evaporation increases with the increase in surface area
. It is because, the larger the surface area that is exposed to air, the more molecules will escape into the air. … When the water is heated, the water molecules tend to move rapidly. This makes the molecules escape faster.
Which factor increases the rate of evaporation?
Temperature
: As the temperature increases, the rate of evaporation also increases. Temperature and rate of evaporation are proportional to each other. Surface area: As the surface area increases, the rate of evaporation increases. The surface area and rate of evaporation are proportional to each other.
Where does more precipitation occur?
The global distribution of precipitation is influenced by the general circulation of the atmosphere, proximity to large bodies of water, and topography. Precipitation is most
abundant where air rises
, and least abundant where it sinks. It also tends to be greater near oceans and lakes, and in higher elevations.
Why does most evaporation occur over the ocean?
Explanation: Most of the Earth’s surface is
covered by the oceans
, and in the oceans — unlike on land — all the surface area is covered by water and available for water evaporation. … This is balanced by the flow of rivers back to the oceans.
Where does ocean precipitation occur?
Precipitation happens when the
water from the ocean evaporates and rises
, cools and then condenses to form clouds. The clouds move along to mountainous areas or high areas, pushed along by the wind. They then precipitate over the land.
What are the four factors affecting the rate of evaporation?
Liquids changes into vapour by the process of evaporation. The factors that affect the rate of evaporation of liquids are
temperature, surface area, wind speed, and humidity
.
What is the rate of evaporation?
Evaporation rate is known as the
rate at which a material vaporizes (or evaporates)
, meaning it will change from liquid to vapor when compared to the rate of vaporization of a specific known material. This quantity represents a ratio, which means it is unitless.
What is evaporation state the factors affecting evaporation?
The rate of evaporation is affected by, (1)
Temperature
: Evaporation increases with an increase in temperature. (2) Surface Area: Evaporation increases with an increase in surface area. (3) Humidity: Evaporation decreases with an increase in humidity. (4) Wind speed: Evaporation increases with wind speed.
What is evaporation state the factors on which the rate of evaporation depends?
The rate of evaporation depends on the
liquid’s exposed surface area
(faster when increased), the humidity of surroundings (slower when increased), the presence of wind (faster when increased) and the temperature (faster when increased).
Which of the following affects the rate of evaporation?
The rate of evaporation is affected by the following factors:
Temperature
: The rate of evaporation increases with an increase in temperature. Surface area: The rate of evaporation increases with an increase in surface area. Humidity: The amount of water vapour present in the air is called humidity.
Where the most weather changes occur?
Most weather happens in
the troposphere
, the part of Earth’s atmosphere that is closest to the ground.
Which area has highest rainfall in Pakistan?
The highest rainfall of 620 millimetres (24 in) was recorded in
Islamabad
in 24 hours on 23 July 2001. The record-breaking rain fell in just 10 hours.
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 do you think will evaporation be greatest near the equator or away from the equator?
Over two-thirds of total global evaporation occurs within 30° of the Equator, because of the higher temperatures in equatorial and tropical areas. Evaporation reaches its greatest values not at the Equator itself, but
between latitudes of 10° and 20° in both hemispheres
.
Why is precipitation high at the equator?
Near the Earth’s equator, solar heating is intense year round. The Sun heats the ocean, evaporating tremendous amounts of water. …
As air rises, it cools, and water vapor condenses into rain
. This daily cycle of heating, evaporation, and convection creates a persistent band of showers and storms around Earth’s middle.
How does evaporation occur?
Evaporation happens
when a liquid substance becomes a gas
. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. … Heat from the sun, or solar energy, powers the evaporation process.
Where does more precipitation occur from the oceans or from the land?
This does vary geographically, though. 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.
Where is most of the water on Earth stored?
The oceans
are, by far, the largest reservoir of water on earth — over 96% of all of Earth’s water exists in the oceans.
What is the most effective method for increasing the rate of evaporation of a given amount of water?
TL;DR: When trying to make water evaporate quickly, it is best to spread the water over a large surface area and
apply heat
as evenly as possible. If using hot air to evaporate water, increased velocity will increase the speed of evaporation.
What is evaporation what will happen to the rate of evaporation on increasing the surface area discuss with an example?
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.
What is high evaporation rate?
For example, a substance with a high evaporation rate will
readily form a vapor which could be inhaled or explode
. Evaporation rates generally have an inverse relationship to boiling points; i.e. the higher the boiling point, the lower the rate of evaporation.
What is evaporation solvent rate?
Evaporation Rate –
How fast the solvent will evaporate in given air flow
. More usually described as Relative Evaporation Rate (RER) with respect to a standard solvent such as n-butyl acetate, nBuAc.
Which of the following has no effect on the rate of evaporation?
Insoluble compounds
are not going to affect the rate of the evaporation. Therefore option D is the correct option. Note: The insoluble impurities are going to stay in the solution and do not affect the process of the evaporation of the solvent from the solution.
What determines the rate of evaporation quizlet?
The larger the surface area of the water the greater the air water interface
and the faster the rate of evaporation. the higher the vapor pressure (moisture content) the closer the air is being saturated and the slower the evaporation rate.
What is evaporation How does the rate of evaporation depend on the speed of wind explain with the help of an example?
Wind speed is one of the factors that affects the rate of evaporation. The rate of
evaporation increases with the wind speed
. … For example:on windy days,fast moving air takes away water vapours from the atmosphere, thereby decreasing its amount, and making room for more. As a result, more evaporation occurs.
Where does climate and weather occur?
Almost all familiar weather phenomena occur in
the troposphere
(the lower part of the atmosphere). Weather does occur in the stratosphere and can affect weather lower down in the troposphere, but the exact mechanisms are poorly understood.
What factor controls evaporation?
Evaporation is the physical process of conversion of a liquid into its vapour state from its surface, with the absorption of heat, at any temperature below the boiling point. The factors affecting Evaporation are : …
Wind, the more the wind blows
, the more is the rate of evaporation.
What is meant by evaporation What are the factors on which the rate of evaporation depend upon B How does evaporation causes cooling?
*
Temperature
: The rate of evaporation increases with an increase in temperature. … When evaporation occurs then than the liquid (mostly water) absorbs all the heat from the surroundings and take it with it and we feel cool. evaporation causes cooling effect because the heat energy is abosorbed by surrounding particles.
Which element is found in the highest concentration in the atmosphere?
By far, the most abundant gas in the Earth’s atmosphere is
nitrogen
, which accounts for about 78% of the mass of dry air. Oxygen is the next most abundant gas, present at levels of 20 to 21%.
What is the main source of atmospheric moisture?
Although
the oceans
are the principal source of atmospheric moisture, transpiration from plant, is also important. But in and areas, transpiration adds little moisture to the atmosphere.
