What factors cause differential heating?
- The curvature of the Earth results in spreading out of solar energy towards the poles and a concentration near the equator.
- The curvature of the Earth results in solar energy having a larger amount of atmosphere to travel through to reach the Earth’s surface near the poles than towards the equator.
What causes differential heating on planet Earth?
It is related to
how the sun’s rays strike the surface of the Earth
. At the equator, the rays strike the Earth almost perpendicular to its surface, warming up a small area.
What causes the differential heating of land and water?
Land gets more solar radiation than water
. Land is a better conductor of heat than water and so it heats up and also cools down faster than water. Water is a better conductor of heat than land and so it heats up and also cools down faster than land.
What is differential heating?
As we learned, differential heating is
the disparity in heating of air over land versus water
. Sea breezes occur when land heats up faster than water, rising and creating a low pressure system. The high pressure air from the sea influxes, creating a sea breeze.
What is differential heating and what causes it quizlet?
What is differential heating?
The different concentrations of sun that hit the earth’s surface
.
What factors contribute to the uneven heating of earth by the sun?
the earth is titled on its axis. the rays of the sun fall directly on the equator, heating the equator more than the other regions. they fall slanting or obliquely as you move north or south of the equator. the heat also depends on the revolution of the earth,when it is summer in the southern and visa versa.
What are the factors which influence the temperature of an area?
- The latitude of the place.
- The altitude of the place.
- Distance from the sea.
- The air- mass circulation.
- The presence of warm and cold ocean currents.
- Local aspects.
How does differential heating and cooling of land and water affect the monsoon of India?
The differential heating and cooling of land and water
creates low pressure on the landmass of India
while the seas around experience comparatively high pressure.
What is a good temperature differential?
To optimize both temperature- and humidity-comfort control, and to protect against excessive equipment cycling, the
cooling differential should be between 0.8°F and 2°F; the heating differential should be between 0.5°F and 1°F
. A heating differential below 0.5°F is too narrow and causes excessive cycles.
What causes the heating of the atmosphere?
The heat source for our planet is
the sun
. Energy from the sun is transferred through space and through the earth’s atmosphere to the earth’s surface. Since this energy warms the earth’s surface and atmosphere, some of it is or becomes heat energy.
How does global circulation relate to differential heating?
What is the primary energy source that produces the differential heating that causes air masses to move across the landscape?
Wind is the movement of air caused by the uneven heating of the Earth by
the sun
.
Which surface would have the lowest albedo quizlet?
What surface on Earth has the lowest Albedo? The surface of Earth with the lowest albedo are
rainforests
.
What are three causes of uneven heating of Earth?
What are 3 reasons why the earth’s surface does not heat equally?
Because the Earth is a sphere, the Sun heats equatorial regions more than polar regions. The atmosphere and ocean work non-stop to even out solar heating imbalances through
evaporation of surface water, convection, rainfall, winds, and ocean circulation
.
What are three factors that affect the heat distribution on Earth?
The latitude of the Place

What does a temperature differential mean?
The “temperature differential” is a pretty scientific term. It has to do with
the difference in temperature between the outside and the inside of your home
. When things are hot out, you want the difference in temperature to be greater since you want it to be cooler in your home.
How do I adjust the differential on my thermostat?
What temp should heat be coming out of vents?
In a properly functioning AC system, it should be approximately
15-20 degrees Fahrenheit
(F). Some HVAC experts may vary these numbers slightly, (14-20 or 16-21), but 15 to 20 is a good range to use for our purposes here.
What are the causes of heating and cooling of atmosphere?
Ans. The process of heating and cooling of the atmosphere takes place in four stages and these stages are
radiation, conduction, convection, and advection
. Radiation is the cycle by which sun-based energy arrives at the earth, and the earth loses energy to space.
What are two primary sources of heat in the atmosphere?
The flow of heat from Earth’s interior to the surface is estimated at 47±2 terawatts (TW) and comes from two main sources in roughly equal amounts:
the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth
.
What makes temperature different at different times?
As the Earth moves, the angle at which sunlight strikes different places on the Earth at the same time of day changes because
the Earth is tilted
. When a particular location is tilted towards the Sun, warmer temperatures occur (summer); when the same place is tilted away from the Sun, colder temperature occur (winter).
What are the 2 factors that cause the Earth to have 3 air cells which circulate thermal energy?
Two additional belts of circulating air exist in the temperate latitudes (between 30° and 60° latitude) and near the poles (between 60° and 90° latitude).
Solar warming of the tropics
drives atmospheric circulation in three cells.
How the differential heating and cooling of land and water affect the climate?
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. Different energy transfer processes also contribute to different rates of heating between land and water.
What kind of differential heating occurs affecting winds during the monsoon season?
The direction of monsoon winds is reversed due to a change in air pressure. –
Temperature variations
arise from uneven heating, which allows air currents (wind) to form, which then transfer heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures) (lower temperatures).
Which of the following factors affect surface and air temperatures?
Surface properties of terrain and vegetation—including
color and texture, transparency, conductivity, specific heat, evaporation, and condensation
—can dramatically affect surface and air temperatures. These properties influence the amount of heat energy absorbed and reflected by the surface.
What causes the differences in air pressure?
This change in pressure is caused by
changes in air density
, and air density is related to temperature. Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air.
What are the three mechanisms that cause air to be displaced into the atmosphere?
6.1. Cooling by uplift
There are three main ways by which uplift of air can occur:
convection, front and orographic (mountain) uplift
. In each case, the rising air is forced to cool by expansion, releasing condensation first as cloud, and if uplift and cooling continues, as rain, hail or snow.
Which surface will have the highest albedo?
Snow and ice
have the highest albedos of any parts of Earth’s surface: Some parts of Antarctica reflect up to 90% of incoming solar radiation. The Dry Valleys are one of the few areas of Antarctica not covered by ice.
What does albedo describe?
Albedo is
an expression of the ability of surfaces to reflect sunlight (heat from the sun)
. Light-coloured surfaces return a large part of the sunrays back to the atmosphere (high albedo). Dark surfaces absorb the rays from the sun (low albedo).
Where are the lowest albedos on Earth Found?
The smallest albedos occur over those
tropical ocean regions where clouds are sparsely distributed
. The ocean surface has an intrinsically low albedo so that when clouds and sea ice are absent, the Earth’s albedo over ocean areas is only 8–10%.
What is responsible for the uneven heating that drives?
The answer is due to uneven heating of the Earth by
the sun
. The Earth is a sphere, and so is the sun. When the earth orbits the sun, the center of the Earth gets more direct sunlight than the poles. This is exacerbated by the Earth’s tilt.
How the differential heating and cooling of land and water affect the climate?
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. Different energy transfer processes also contribute to different rates of heating between land and water.
What effect does this have on the heating at different latitudes of the Earth?
Because the angle of radiation varies depending on the latitude, surface temperatures on average are
warmer at lower latitudes and cooler at higher latitudes
(even though higher latitudes have more hours of daylight during the summer months).
