How is solar radiation distributed throughout the Earth?
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor dust and ozone and 48 percent passes through the atmosphere and is absorbed by the surface. Thus about 71 percent of the total incoming solar energy is absorbed by the Earth system. … The remaining 48% is absorbed at the surface.
What are the three factors that determine the unequal distribution of sun energy on Earth?
The inclination of the Earth’s orbital plane and the fact that it is elliptical together with the inclination of the Earth’s rotational axis are therefore the cause of the differences between the various climatic zones of the Earth of the alternation of the seasons and of the meteorological variations connected to …
What are the effects of unequal duration and unequal distribution of sunlight?
EXPLANATION: The factors which influence the unequal distribution of sunlight is the Angle of Incidence. The rays of the sun heat the earth surface at different angles because of the round shape of the earth. It also depends on the duration of the day and the sunshine and the transparency within the atmosphere.
What are two reasons that solar radiation is different at different latitudes?
Different parts of Earth’s surface receive different amounts of sunlight (Figure below). The Sun’s rays strike Earth’s surface most directly at the equator. This focuses the rays on a small area.
How does reflection of solar radiation from Earth’s surface add to the effects of uneven solar heating in creating a pole to equator heat imbalance?
How does reflection of solar radiation from Earth’s surface add to the effects of uneven solar heating in creating a pole-to-equator heat imbalance? … -The overall effect of these albedo differences is to increase the solar heating imbalance between the poles and the tropics.
How does unequal distribution of heat over the earth causes variation of weather and climate?
The amount of heat received by different parts of the earth is not the same. This variation causes pressure difference in the atmosphere. … Thus the weather and climate are ultimately caused by the unequal distribution of heat over the planet earth over space and time.
Which of the following is most responsible for the uneven distribution of solar energy on Earth?
Earth’s spherical shape results in an uneven distribution of sunlight reaching Earth’s surface. This uneven distribution is most directly responsible for differences in what climatic variable at different latitudes on Earth’s surface? the length of a year is determined by the amount of time it takes what to happen?
What causes solar radiation?
Cloud cover air pollution latitude of a location and the time of the year can all cause variations in solar radiance at the Earth’s surface. The amount of energy reaching the surface of the Earth every hour is greater than the amount of energy used by the Earth’s population over an entire year.
How does solar radiation affect the atmosphere?
As solar radiation passes through the atmosphere gasses dust and aerosols absorb the incident photons. Specific gasses notably ozone (O3) carbon dioxide (CO2) and water vapor (H2O) have very high absorption of photons that have energies close to the bond energies of these atmospheric gases.
What type of radiation is solar radiation?
All of the energy from the Sun that reaches the Earth arrives as solar radiation part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light ultraviolet light infrared radio waves X-rays and gamma rays. Radiation is one way to transfer heat.
How do solar flares affect the amount of radiation emitted from the sun?
The most powerful solar flares are huge bursts of x-rays and electrified hot gas called coronal mass ejections (CMEs) which hurl solar matter into space. … The explosion that creates the CME accelerates the protons around the Sun to nearly the speed of light.
What happens to solar radiation after it reaches Earth?
What happens to solar radiation after it reaches Earth? … – Nearly 70% of solar radiation is absorbed by the earth’s atmosphere and oceans and the rest is reflected back into space. The absorbed radiation is re-emitted as infrared radiation.
How does solar energy affect Earth’s atmosphere and surfaces?
The radiation warms the Earth’s surface and the surface radiates some of the energy back out in the form of infrared waves. As they rise through the atmosphere they are intercepted by greenhouse gases such as water vapor and carbon dioxide. Greenhouse gases trap the heat that reflects back up into the atmosphere.
What are three causes of uneven heating of Earth?
The factors that contribute to the uneven heating of earth by the sun include latitude seasons and the time of the day. Most important point to remember in uneven heating is temperature differences.
What factors causes the sun to heat the Earth unevenly?
The factors that contribute to the uneven heating of the Earth by the sun include latitude seasons and the time of the day.
What is caused by unequal heating of Earth’s surface?
Unequal heating of the earth’s surface causes temperature differences which cause pressure differences. Lower temperatures (heavy air) cause higher air pressure. Wind direction is described as where the wind is coming from. For example a northerly wind blows from the north to the south.
What is the consequence of having unequal amounts of incoming radiation as a function of latitude?
At higher latitudes the angle of solar radiation is smaller causing energy to be spread over a larger area of the surface and cooler temperatures.
What affects net radiation?
What factors affect the amount of solar energy that reaches the Earth’s surface?
Latitude climate and weather patterns are major factors that affect insolation—the amount of solar radiation received on a given surface area during a specific amount of time. Locations in lower latitudes and in arid climates generally receive higher amounts of insolation than other locations.
What is the dependent variable that impacts the amount of solar energy in a location?
There are two main variables that affect the amount of solar energy delivered at every part of the world: a) Sun rays inclination at the specific geographical point and b) Thickness of the atmosphere between the specific point and the sun.
How does the uneven heating of Earth’s surface affect Earth’s weather patterns?
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 uneven heating of the earth cause wind?
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.
How does the uneven heating of the earth cause ocean currents?
Earth receives more solar radiation at the equator than it does at the poles this uneven distribution of heat creates pressure differences which in turn cause the movement of air or wind. Because the poles are either north or south of the equator winds have a northward or southward flow.
What is albedo effect?
What energy source is a result of the uneven heating of Earth?
Energy from moving air
Wind is caused by uneven heating of the earth’s surface by the sun. Because the earth’s surface is made up of different types of land and water it absorbs the sun’s heat at different rates.
How does radiation heat up the atmosphere Class 6?
Explanation: The sun’s radiation hits the ground on Earth which results in heating of it. Now since the ground is heated the temperature is high so it rises up due to conduction. This is how heat energy is released into the atmosphere.
Why does the equator receive more solar radiation?
The equatorial region receives more solar radiation not only because the Sun’s rays hit the region more directly (i.e. at less of an angle) but also because they travel through less of the atmosphere to get there. … The main consequence is that less energy is received in polar regions so temperatures are cooler.
What is spectral distribution of solar radiation?
Which of the following affects the amount of solar radiation received by a location or water body *?
4. Which of the following affects the amount of solar radiation received by a location or water body?
