Once the incoming solar radiation is absorbed by Earth’s surface, it is then given off as heat energy. This heat energy is then dispersed up into the atmosphere. This energy then warms the surrounding air and is absorbed by clouds.
Water vapor in the atmosphere then absorbs this heat and condenses into tiny droplets. This allows the water droplets to become clouds which allows temperatures to stay cooler on the Earth’s surface.
This cooled air then flows downwards and creates wind. The wind then warms any surface it touches. This warm air then rises back up into the atmosphere until it cools and sinks back down, as a result, creating a cycle known as the atmospheric circulation.
Any excess heat then escapes the atmosphere through infrared radiation, allowing the Earth to maintain a stable climate.
What happens to solar radiation when it exits the atmosphere?
When solar radiation exits the atmosphere, it enters what is known as the vacuum of space. This vacuum is a void that requires something to transfer energy through, as it is incapable of transferring energy through a medium like air.
The laws of physics dictate that any energy that enters a vacuum is basically lost, meaning that the solar radiation is eventually lost as the radiation cover vast distances from the point at which it left the atmosphere.
As the radiation passes through the vacuum, it may deviate slightly due to the gravitational pull of nearby bodies. However, it’s ultimate course does eventually lead back to the sun, meaning that the radiation simply returns to the source from which it came, having no impact on anything else on the way.
What happens to all the solar radiation arriving at the Earth every day why doesn’t the Earth continue to warm up in response to the solar illumination?
The short answer is that the Earth does continue to warm up in response to the solar radiation – the average global temperature has increased by nearly 1. 7 degrees Fahrenheit since 1880 according to NASA.
However, this process is moderated on a number of fronts. Some solar radiation is reflected off the Earth’s surface due to features like snow and ice, clouds, and desert sand. This can bring about a cooling effect.
In addition to reflected radiation, some of the solar radiation is absorbed by the atmosphere and converted to infrared radiation which is then either absorbed by the greenhouse gasses of the atmosphere, or it escapes back out of the atmosphere into the universe.
Lastly, some of the solar radiation is absorbed by the Earth’s surface which warms the Earth’s surface air and acts as a heat source for the natural changes in the climate. This constant process of energy balance helps maintain the Earth’s atmosphere and temperature, keeping it relatively stable.
What will happen to our solar system if the sun will suddenly disappear?
The effects of the sun suddenly disappearing would be catastrophic for our solar system. All of the planets would be flung out of their orbits, possibly colliding with each other or going beyond the reaches of our system.
Life on Earth would be completely extinguished as the lack of sunlight would make it impossible for our planet to sustain life. Additionally, an absence of the sun would cause the other planets in the system, such as Jupiter and Saturn, to rapidly cool and become lifeless balls of rock and ice.
Without the sun’s immense gravitational push, asteroids and comets would be sent on a trajectory that could either collide with our planets or exit the boundaries of our solar system altogether. Without the light and warmth of the sun, it would be much colder in the solar system and our planets would be unable to absorb energy from elsewhere.
In short, if the sun suddenly disappeared, our solar system would be put in danger of becoming a dead and lifeless place.
Where will most of the energy go after it is reflected from the Earth’s surface?
Most of the energy that is reflected from the Earth’s surface will be scattered back into the atmosphere. Depending on the angle of the incoming energy, some of the energy may be directly reflected back into space, while some may be scattered in other directions and eventually be absorbed by the Earth’s surface.
The atmosphere also acts like a greenhouse, trapping some of the energy and reflecting it back down towards the surface. This means that a significant amount of the energy that is reflected will end up being reabsorbed by the Earth’s surface, although a small amount may escape back into space or be scattered in other directions.
What happens to the following when heat is absorbed?
When heat is absorbed, molecules in the material subjected to the heat begin to move faster, increasing their kinetic energy. This leads to a rise in temperature, causing atoms or molecules to become more excited and energetic.
This increased activity from the additional heat energy causes particles to spread out, meaning that the material expands as heat energy is absorbed. This is why walls and other materials expand on hot days.
Most materials absorb heat by directly absorbing energy from their surroundings. For example, when a metal object is held near a flame, the metal absorbs heat energy directly from the flame and becomes warmer.
Heat can also be transferred from one material to another by the process of convection, which is the transfer of heat from one place to another by the movement of heated fluids. Additionally, some materials can also absorb heat energy by the process of radiation, where infrared radiation from an object is absorbed by the material and converted into heat energy.
What would happen if the Sun did not send radiation to Earth’s surface?
If the Sun did not send radiation to Earth’s surface, it would have devastating impacts on the planet and all living organisms. Without the Sun’s radiation, there would be no source of warmth or energy for fueling plants and animals.
The lack of radiation would cause temperatures to drop significantly, likely resulting in global cooling, extreme weather changes, and longer winters.
The reduced sunlight would also prevent photosynthesis, which is the process by which all green plants produce energy from light, resulting in the death of all plant life. As plants provide the foundational energy source for the food web, this would lead to the extinction of countless animal species.
In addition, the lack of a light source would cause permanent darkness, which would make it difficult for many animals to navigate their environment, reproduce, and find food sources.
In summary, if the Sun did not send radiation to Earth’s surface, it would have catastrophic effects on all life forms, causing extreme global cooling, photosynthesis to cease, and darkness to blanket the planet.
What happens to the incoming solar radiation?
When incoming solar radiation reaches Earth, it is either absorbed or reflected by surface features such as land, water, and atmosphere. Land surfaces absorb most of the radiation, while water absorbs much less; this is why land areas tend to be warmer than aquatic bodies of water.
Soil moisture and vegetation can also affect absorption. After absorption, some of the radiation is transformed into longwave infrared radiation, which is then emitted back into the atmosphere. Clouds also affect incoming solar radiation, as each cloud particle absorbs and scatters radiation.
Ultimately, some of the incoming solar radiation is responsible for warming the Earth, while some of the energy is returned to space. This balance of incoming and outgoing energy determines Earth’s climate.
What would happen to Earth’s temperature if the energy absorbed from the sun was less than the emitted energy leaving the Earth?
If the energy absorbed from the sun were to be less than the energy emitted from the Earth, the overall temperature of the Earth would decrease significantly. This would be due to the fact that the Earth relies upon the sun’s energy to warm the planet, but if less energy was absorbed, then the Earth would be unable to maintain its current temperature.
The decrease in temperatures could cause a number of problems. Sea levels could drop due to increased melting of the polar ice caps, and the growing season for many crops would be shortened or even eliminated.
There could also be potential for more extreme weather due to changes in air pressure caused by the overall decrease in temperature. Of course, it’s important to remember that any change to Earth’s temperature would cause a cascade of unpredictable effects that could have far-reaching consequences.
When solar radiation hits the surface of the Earth what happens to most of it?
When solar radiation hits the surface of the Earth, most of it is absorbed by the land and water. This absorbed energy then warms the surface of the Earth, which in turn heats the air above it. The warm air rises, allowing cooler air from the surrounding environment to move in and take its place.
This process helps maintain a fairly constant global temperature. Additionally, some of the solar radiation is reflected by the Earth’s surface, also helping to maintain a relatively constant global temperature.
The remaining energy is either radiated back into space or absorbed by the atmosphere. This absorbed energy is then used to drive weather patterns throughout the planet.
What happens to energy since it Cannot be destroyed?
Energy cannot be destroyed, meaning that the total amount of energy in the universe always remains the same. This is due to the fact that energy is always conserved, meaning that it can be transformed from one form to another, but the total amount of energy remains constant.
In other words, energy is neither created nor destroyed – it only changes forms. For instance, when an object falls to the ground due to gravity, the potential energy of the object is converted into kinetic energy – the energy of motion – once it reaches the ground.
Similarly, the combustion of gasoline releases energy in the form of thermal energy, or heat. All of these examples demonstrate that energy is transformed from one form to another but never lost, which is why energy is conserved.
How is incoming solar radiation reflected?
Solar radiation is reflected in two primary ways: reflection and scattering of the light. Reflection is when all of the light that hits a surface is bounced away, which occurs when the light strikes a non-absorbent surface such as water or glass.
This can be seen when sunlight bounces off a mirror or a body of water and is then scattered in different directions. Scattering is when the light is partially absorbed by the surface and then scattered around the area in the form of smaller particles.
This is seen when sunlight hits clouds, dust particles, and other objects in the atmosphere. This incoming radiation is then dispersed and reflected in different directions, which allows for it to reach different areas and eventually provide heat and light that is necessary for life.
How is solar energy absorbed and emitted by Earth’s surface?
Solar energy is absorbed by Earth’s surface in a variety of ways. The most common way for solar energy to be absorbed is through direct solar radiation. This type of radiation is directly produced by the Sun and is present in the form of visible light and infrared radiation.
When direct solar radiation hits Earth’s surface (such as the oceans and landmasses), its energy is transferred to the surface and can either be released as heat or reflected back into space. Additionally, ultraviolet radiation from the sun can also be absorbed by atmospheric gases, which then can be released as heat energy by the Earth’s surface.
Heat energy that is absorbed by Earth’s surface can then be emitted back into the atmosphere in a variety of ways. This is usually done through evaporation, which is when liquid molecules in the atmosphere are heated and transferred into a gas before they are emitted back into the atmosphere.
Conduction and convection are also forms of heat transfer that occur when the Earth’s surface heats the air and water molecules in the atmosphere. These heat energy emissions can also be converted into electricity, producing what is known as solar thermal energy.
Ultimately, solar energy is absorbed and emitted by the Earth’s surface in a variety of ways, which all serve to provide us with heat and electricity.
What is the amount of solar energy received by the Earth called?
The amount of solar energy that reaches Earth’s atmosphere and is then available for life forms to absorb is known as the solar irradiance, or the solar constant. The solar irradiance received by Earth on a given day is approximately 1,366 Watts per square meter (W/m2).
This amount can vary slightly depending on the distance between Earth and the Sun. In a way, the solar constant acts as a measure of the total daily energy available to life on Earth. The energy that is imbedded within the solar irradiance causes nearly all of the phenomena on Earth, including the existence of the weather, the rotation of the planet, the growth of plants and animals, and the availability of geothermal energy.
In short, it is essential for life on Earth as we know it.
Which part of the earth receives the most solar energy answer?
The part of the earth that receives the most solar energy is the equatorial region. The equator is an imaginary line that encircles the earth near its center, and is the halfway point between the North Pole and the South Pole.
This region lies in close proximity to the sun, resulting in it receiving the most direct rays of sunlight. The equatorial regions have the longest days and the highest amount of incoming solar energy year-round.
This is because the sun’s rays hit the equator more directly than other parts of the world. The equatorial region also experiences the warmest temperatures and the highest amount of humidity due to its proximity to the sun’s rays.
Due to its abundance of sunlight, the equatorial region is home to some of the most densely populated and lush areas on the planet and has led to a rich and diverse array of flora and fauna.
