    The Earth’s energy budget is the balance between the incoming energy from the Sun and the outgoing energy from the Earth. The incoming energy is in the form of shortwave radiation, while the outgoing energy is in the form of longwave radiation. The Earth’s AtmosphereAtmosphere absorbs some of the incoming shortwave radiation, and the rest is reflected back into space. The atmosphere also emits longwave radiation, which is absorbed by the Earth’s surface. The Earth’s surface emits longwave radiation back into space, and some of it is absorbed by the atmosphere.

The Earth’s energy budget is in balance, which means that the amount of incoming energy is equal to the amount of outgoing energy. However, human activities are causing the Earth’s energy budget to change. Greenhouse gases in the atmosphere trap some of the outgoing longwave radiation, which causes the Earth to warm. This is called the greenhouse effect.

The greenhouse effect is a natural process that helps to keep the Earth warm. However, human activities are causing the greenhouse effect to become stronger, which is causing the Earth to warm at an alarming rate. This warming is causing a number of changes to the Earth’s climate, including rising sea levels, more extreme weather events, and changes in plant and animal life.

Albedo is the fraction of incoming solar radiation that is reflected back to space by a surface. The albedo of a surface depends on its composition and texture. For example, snow has a high albedo, while dark SoilSoil has a low albedo.

Atmospheric absorption is the process by which gases in the atmosphere absorb some of the incoming solar radiation. The amount of absorption depends on the wavelength of the radiation and the concentration of the gas. For example, water vapor absorbs most of the incoming infrared radiation.

The greenhouse effect is a natural process that helps to keep the Earth warm. However, human activities are causing the greenhouse effect to become stronger, which is causing the Earth to warm at an alarming rate.

Insolation is the amount of solar radiation that is received by a surface. The insolation at a particular location depends on the latitude, time of year, and time of day.

Latent heat is the heat that is absorbed or released when a substance changes phase. For example, when water changes from liquid to vapor, it absorbs latent heat. When water changes from vapor to liquid, it releases latent heat.

Net radiation is the difference between the incoming solar radiation and the outgoing longwave radiation. The net radiation at a particular location depends on the albedo, atmospheric absorption, and greenhouse effect.

Outgoing longwave radiation is the longwave radiation that is emitted by the Earth’s surface. The outgoing longwave radiation at a particular location depends on the temperature of the Earth’s surface.

Radiative forcing is the change in the Earth’s energy budget caused by a change in the concentration of greenhouse gases. Radiative forcing is positive when the change causes the Earth to warm, and negative when the change causes the Earth to cool.

Shortwave radiation is the electromagnetic radiation that is emitted by the Sun. Shortwave radiation has a wavelength of less than 4 micrometers.

Solar constant is the average amount of solar radiation that is received by the Earth’s atmosphere. The solar constant is equal to 1361 watts per square meter.

Stefan-Boltzmann law is the law that states that the power emitted by a blackbody is proportional to the fourth power of its temperature. The Stefan-Boltzmann constant is equal to 5.6703
Albedo

Albedo is the fraction of solar radiation that is reflected by a surface. It is a measure of how reflective a surface is. A surface with a high albedo reflects more sunlight than a surface with a low albedo.

Atmospheric absorption

The atmosphere absorbs some of the solar radiation that reaches it. This absorption is caused by greenhouse gases, such as water vapor and carbon dioxide. The absorbed radiation is then re-radiated back to Earth as heat.

Atmospheric greenhouse effect

The atmospheric greenhouse effect is the process by which the atmosphere traps heat from the sun. This heat is trapped by greenhouse gases, such as water vapor and carbon dioxide. The trapped heat warms the Earth’s surface.

Earth’s energy budget

The Earth’s energy budget is the balance of incoming and outgoing energy at the Earth’s surface. The incoming energy comes from the sun, while the outgoing energy is radiated back to space as heat. The Earth’s energy budget is in balance, meaning that the amount of incoming energy equals the amount of outgoing energy.

Electromagnetic radiation

Electromagnetic radiation is a form of energy that travels in waves. It is made up of photons, which are tiny particles of light. Electromagnetic radiation can be divided into different types, such as visible light, ultraviolet light, and infrared light.

Greenhouse gases

Greenhouse gases are gases in the atmosphere that trap heat. This trapping of heat warms the Earth’s surface. Greenhouse gases include water vapor, carbon dioxide, methane, and nitrous oxide.

Insolation

Insolation is the amount of solar radiation that reaches the Earth’s surface. It is measured in watts per square meter (W/m2). The amount of insolation varies depending on the time of day, the time of year, and the latitude.

Latent heat

Latent heat is the heat that is absorbed or released when a substance changes state. For example, when water changes from a liquid to a gas, it absorbs latent heat. This latent heat is used to power the water cycle.

Net radiation

Net radiation is the difference between incoming and outgoing radiation at the Earth’s surface. It is a measure of the amount of energy that is absorbed by the Earth’s surface.

Outgoing longwave radiation

Outgoing longwave radiation is the radiation that is emitted by the Earth’s surface. It is a form of infrared radiation. The outgoing longwave radiation helps to cool the Earth’s surface.

Radiative forcing

Radiative forcing is the change in the Earth’s energy balance caused by a change in the concentration of greenhouse gases. Radiative forcing is positive when it causes the Earth to warm, and negative when it causes the Earth to cool.

Shortwave radiation

Shortwave radiation is the radiation that is emitted by the sun. It is a form of visible light. The shortwave radiation is absorbed by the Earth’s surface, and it is then re-radiated as longwave radiation.

Solar constant

The solar constant is the amount of solar radiation that reaches the Earth’s atmosphere per unit area. It is measured in watts per square meter (W/m2). The solar constant is about 1361 W/m2.

Stefan-Boltzmann law

The Stefan-Boltzmann law is a law of physics that states that the amount of energy that is radiated by a blackbody is proportional to the fourth power of its temperature. The Stefan-Boltzmann constant is 5.670373 × 10-8 W/m2/K4.

Surface albedo

Surface albedo is the fraction of solar radiation that is reflected by the Earth’s surface. It is a measure of how reflective the Earth’s surface is. A surface with a high albedo reflects more sunlight than a surface with a low albedo.

Thermal radiation

Thermal radiation is a form of electromagnetic radiation that is emitted by all objects that have a temperature above absolute zero. The amount of thermal radiation that is emitted by an object is proportional to its temperature to the fourth power.

Terrestrial radiation is the radiation that is emitted by the Earth’s surface. It is a form of infrared radiation. The terrestrial radiation helps to cool the Earth’s surface.
Question 1

The Earth’s energy budget is the balance between incoming and outgoing energy. The incoming energy comes from the Sun, and the outgoing energy is radiated back into space. The Earth’s atmosphere plays a role in this balance by absorbing some of the incoming energy and re-emitting it back to the Earth’s surface. This process is called the greenhouse effect.

Which of the following is not a factor that affects the Earth’s energy budget?

(A) The Earth’s albedo
(B) The Earth’s atmosphere
(CC) The Sun’s output
(D) The Earth’s rotation

Answer

(D) The Earth’s rotation does not affect the Earth’s energy budget. The other factors do affect the Earth’s energy budget.

Question 2

The Earth’s albedo is the fraction of incoming solar radiation that is reflected back to space. The Earth’s albedo is affected by the Earth’s surface, which can be either land or water. Land has a lower albedo than water, so it reflects less sunlight back to space. This means that land absorbs more energy from the Sun than water does.

Which of the following would cause the Earth’s albedo to increase?

(A) An increase in the amount of ice on the Earth’s surface
(B) An increase in the amount of vegetation on the Earth’s surface
(C) An increase in the amount of dust in the Earth’s atmosphere
(D) All of the above

Answer

(D) All of the above would cause the Earth’s albedo to increase. Ice, vegetation, and dust all reflect sunlight back to space.

Question 3

The greenhouse effect is a natural process that helps to keep the Earth’s climate warm. Greenhouse gases in the Earth’s atmosphere trap heat from the Sun, which helps to keep the Earth’s surface warm.

Which of the following is not a greenhouse gas?

(A) Water vapor
(B) Carbon dioxide
(C) Methane
(D) Oxygen

Answer

(D) Oxygen is not a greenhouse gas. The other gases are greenhouse gases.

Question 4

Insolation is the amount of solar radiation that reaches the Earth’s surface. The amount of insolation that reaches the Earth’s surface varies depending on the Earth’s latitude. The Earth’s surface receives more insolation at the equator than at the poles.

Which of the following would cause the Earth’s surface to receive more insolation?

(A) The Earth’s orbit around the Sun becomes more elliptical
(B) The Earth’s axis tilts more towards the Sun
