How does the uneven heating of land and water contribute to monsoons in India?
In India the land gets heated much more in summer than the water in the Indian ocean. This uneven heating of land’ and ‘water in Indian ocean’ during summer generates monsoon winds from the Indian ocean. … During summer wind blows from the oceans towards land. In winter the direction of wind flow gets reversed.
When water evaporates from a surface which of the following occur?
The evaporation of water happens over a wide range of temperatures. At any temperature the molecules of a substance are moving at a variety of speeds (kinetic energies). Evaporation happens when the molecules at the surface of a liquid move fast enough to break away from other molecules in the liquid and become a gas.
When water evaporates what happens to the energy that was used to evaporate the water?
When something evaporates it basically takes in heat and when it condenses it cools down by giving out the heat into the atmosphere. So the energy goes into the atmosphere or surroundings. Part of the energy is used to force the H and O atoms closer to one another.

Uneven Heating of Land vs Water
Differential Heating of Land and Water Surfaces – Class 5
Is there a difference between heating land and heating water?
It takes less energy to change the temperature of land compared to water. This means that land heats and cools more quickly than water and this difference affects the climate of different areas on Earth. … The result is that a greater volume of water is heated at a slower rate.
Why does land heat and cool faster than water?
Note: Land has lower heat capacity and requires less heat to increase its temperature and water has higher heat capacity and requires more heat to increase its temperature. Hence land heats up and cools down faster than water.
Water evaporation experiment
What factors cause land-water heating differences?
latitude altitude cloud cover and land-water heating differences.
Which of the following is incorrect regarding the differences in the heating of land and water?
Which of the following is incorrect regarding the differences in the heating of land and water? Land has a higher specific heat than water. refers to the fact that land is opaque and water is transparent. … latitude altitude land-water heating differences cloud cover ocean currents and sea-surface conditions.
How does water heat the earth?
Heat radiated from Earth’s surface is absorbed by water vapor molecules in the lower atmosphere. The water vapor molecules in turn radiate heat in all directions. Some of the heat returns to the Earth’s surface. Thus water vapor is a second source of warmth (in addition to sunlight) at the Earth’s surface.
How does the differential heating of land and water cause wind?
At night land cools quickly without the heat of the Sun. However water heats and cools much more slowly than land and consequently the air over the ocean becomes warmer than the air over land. … This creates a land breeze that causes winds from the land to the water at night.
Does land have a higher heat capacity than water?
The heat capacity is the product of the specific heat and the mass (in g) of the material. Oceans have a greater heat capacity than land because the specific heat of water is greater than that of dry soil and because a mixing of the upper ocean results in a much larger mass of water being heated than land.
Why do land and water areas warm and cool at different rates quizlet?
Land heats more rapidly and to higher temperatures than water. Land cools more rapidly and to lower temperatures than water. Why do land and water heat and cool differently? Water is highly mobile so as water is heating convection distributes the heat through a considerably larger mass.
How does differential heating and cooling of land and water help in understanding mechanism of monsoon?
Differential heating and cooling of land and water creates low pressure on the land of India while the seas around experience comparatively high pressure leading to the shifting of winds from south to north.
What causes differences in temperature?
The temperature of the air is caused by the combination of air water and land working together. Those three factors heat and cool areas at different rates. Temperature also varies by the time of day the season or even the year.
Why does land absorb heat faster?
Land surfaces absorb much more solar radiation than water. This is due to the fact that most land surfaces are darker than water which of course means more absorption of solar radiation and heat. … Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy.
Can the temperature of land affect the temperature of air as the air moves over the land?
During the day the land surface heats up faster than the water surface. Therefore the air above the land is warmer than the air above the ocean. Now recall that warmer air is lighter than cooler air.
What is the effect of heat on land and water?
Solar heating of the Earth’s surface is uneven because land heats faster than water and this causes air to warm expand and rise over land while it cools and sinks over the cooler water surfaces.
What causes the temperature difference between land and sea when heated by solar radiation?
The heat consumed by the oceans is spread over a larger depth than the heat absorbed by land surfaces due to mixing. … – The amount of solar energy reaching the earth’s surface defines the degree and direction of differential heating between land and sea.
In what ways do land and water areas respond differently to equal insolation?
Thermal Responses of Water Versus Other Earth Materials Due to their differences in specific heat oceans (water) heat up during the day differently than land. If the same amount of insolation strikes water and land the land will increase in temperature 4 degrees (K or C°) for every degree the water increases.
Why does the land lose heat more quickly at night than a body of water does?
So specific heat capacity of the water is higher compared to land. … So it takes much time for the heat to heat up the water than land. During night time the heat received by the land is reflected back into the atmosphere. So as the result it loses more heat quicker than the water during this time.
How does differential heating cause global circulation?
Earth’s orbit around the sun and its rotation on a tilted axis causes some parts of Earth to receive more solar radiation than others. This uneven heating produces global circulation patterns. For example the abundance of energy reaching the equator produces hot humid air that rises high into the atmosphere.
How does the difference in temperature between water and land affect weather systems?
Large bodies of water such as oceans seas and large lakes affect the climate of an area. Water heats and cools more slowly than land. Therefore in the summer the coastal regions will stay cooler and in winter warmer. A more moderate climate with a smaller temperature range is created.
How does temperature affect land and sea breezes?
The greater the temperature differences between land and sea the stronger the land breezes and sea breezes. After sunset the air mass above the coastal land quickly loses heat while the air mass above the water generally remains much closer to it’s daytime temperature.
What is unequal heating of air land and water?
The uneven heating of land and water leads to the creation of fronts. A frontal boundary is a dividing line between two different air masses. Fronts may also mark the position of unsettled weather such as thunderstorms. The strength of the front depends on how large the temperature difference becomes.
What is the fundamental difference between water and land that is responsible for sea land breezes and monsoons?
The water stays warmer than the land during the night and the winter. These differences in heating cause local winds known as land and sea breezes (Figure below). A sea breeze blows from sea to land during the day or in summer. That’s when air over the land is warmer than air over the water.
Why do temperatures differ between air land and water?
But why does this occur? Simply it is the result of uneven heating between the land and water. Land changes temperature faster than water does. Therefore as the sun shines and begins to heat the Earth’s surface the land’s temperature increases faster than the water’s temperature. See also how is water important to living things
Why does land heat up faster than water quizlet?
Terms in this set (5) Land heats up and cools down more quickly than water. … Heat energy is absorbed by the cooler land which then cools the atmosphere. Water heat Capacity. Water takes a longer to cool down so the air over water usually stays warmer longer.
How does uneven heating of land at different places produce wind?
Wind Is Caused By The Uneven Heating Of The Earth See also how many countries border portugal Thus the air absorbs different amounts of = heat making it warm in places and cool in others. As air gets warmer its particles spread out. In other words air expands on heating. This makes the air lighter or less dense so it rises.
Why do temperature contrasts decrease in a warmer climate?
Land has a much lower capacity than ocean to store heat. Why do temperature contrasts (e.g. Night vs Day) decrease in a warmer climate? Because temperature variations in our current climate are generally caused by variations in the distribution of sunlight. … Thus temperature contrasts will decrease.
What happens to the temperatures of water and soil after heating?
Evaporation: The evaporation of water from the soil requires a large amount of energy. Soil water utilises the energy from solar radiation to evaporate thereby rendering it unavailable for heating up of the soil. Thus the greater the rate of evaporation the more a soil is cooled and its temperature decreases.
How is the heating of land different from the heating of water quizlet?
How do the heating of land and water differ? Land heats more rapidly and to higher temperatures then water. Land also cools more rapidly and to lower temperatures than water.
How does the uneven heating of land vs water affect the weather in the desert?
As the air descends it increases in temperature once again due to heating from the land. … The tropics however are covered in water and plants which tend to change temperature much more slowly. This is why air in the desert is much hotter than air in the tropics even though deserts get less direct sunlight.
How Does Evaporation Affect Land-water Heating Differences??
How does evaporation affect land-water heating differences? Evaporation tends to lower temperatures more over water bodies than over land. During summer cities located near the coast are than those in the interior at the same latitude while in the winter they are .
Which cools off faster quizlet?
Because water has a higher specific heat than land it cools more quickly.
When water evaporates the energy that was used to evaporate the water ___?
Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together which is why water easily evaporates at the boiling point (212° F 100° C) but evaporates much more slowly at the freezing point.
