Why does earths atmosphere absorb radiation?
It absorbs radiation to protect it. It protects from UV rays.
How does albedo affect the behavior of solar radiation reaching earths surface?
Albedo refers to the reflectivity of a surface. Surfaces with high albedo reflect more solar radiation back into space, which can cool the Earth's surface and lower temperatures. Surfaces with low albedo absorb more solar radiation, leading to warming of the Earth's surface.
How does the ozone layer reduces the amount of ultraviolet radiation that reaches earths surface?
Ozone layer contains ozone molecules in abundance. These molecules decompose themselves to absorb ozone.
What three gasses present in Earths atmosphere absorb solar radiation?
Carbon dioxideMethaneNitrous Oxide
Why are carbon dioxide water vapor and other greenhouse gases important to life on Earths surface?
They absorb radiant energy emitted by Earths surface
How does the presence of oxygen in our atmosphere help reduce the amount of ultraviolet radiation that reaches the earths surface?
Oxygen in the atmosphere helps to absorb and scatter incoming ultraviolet (UV) radiation from the sun. This process occurs in the stratosphere, where oxygen molecules break apart the incoming UV radiation. This absorption and scattering of UV radiation by oxygen prevent a large amount of harmful UV radiation from reaching the Earth's surface.
Why is Co2 is a greenhouse gas?
CO2 is a greenhouse gas because it absorbs and traps heat in the Earth's atmosphere. When sunlight hits the Earth's surface, some of the heat is reflected back into space as infrared radiation. CO2 molecules in the atmosphere absorb this infrared radiation, preventing it from escaping into space and thus leading to a warming effect.
How much solar energy is absorbed and how much is reflected from the earth's surface?
At the earth's surface about 51% of incoming solar radiation is absorbed, and 4% is reflected back into space.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
What is the reflectivity of a surface called?
The reflectivity of a surface is called its albedo. It is a measure of how much of the incoming radiation that hits a surface is reflected back without being absorbed. High-albedo surfaces reflect more light, while low-albedo surfaces absorb more light.
What factors affect the amount of radiation a surface absorbs?
Factors that affect the amount of radiation a surface absorbs include the type of material, color, texture, and angle of the surface. Darker colors tend to absorb more radiation than lighter colors, and rough surfaces absorb more radiation than smooth surfaces. The angle of the surface plays a role in how much direct sunlight it receives.
Which type of land surface will most likely absorb the greatest amount of incoming solar radiation?
A dark, rough surface such as asphalt or forest will absorb the greatest amount of incoming solar radiation, as they have low albedo (reflectivity) and a large surface area for absorption.
What percentage of solar radiation does the ocean absorb?
The ocean absorbs approximately 70% of the solar radiation that reaches its surface. This absorption plays a crucial role in regulating the Earth's climate by storing heat and influencing weather patterns. The remaining solar radiation is either reflected back into the atmosphere or absorbed by land and ice surfaces.
