If there was more snow and ice on the earth then more of the sun's radiation would be reflected?

Yes this is correct, this is one of the many reasons why global warming would become self sustaining at some certain point.
Glaciers and the Arctics reflect a lot of sun light back to space, which avoids that even more heat from the sun would be absorbed by the Earth.
But because of global warming, these glaciers and Arctics start to melt away, causing more heat to be absorbed, causing more global warming which melts more snow away.
Another problem with this melting is that the melted snow releases a lot of CO2 into the atmosphere, strengthening the greenhouse effect.

Does ice reflect sunlight like a mirror?
Sea ice has an albedo of between 0.5 and 0.7. This means that it reflects between 50 and 70% of the sun's radiation (that lands on the ice).Ice with snow on it has a higher albedo, between 70 and 90%.Of the 100% of the sun's radiation that reaches the earth, 4% is reflected by the earth's surface, with about 2% reflected by ice.
Does the earth or the sun emit more infrared radiation?
true
What is more reflective toward radiation mirror or aluminum foil?
I would have to say aluminum foil, since radiation can travel through glass. radiation is reflected from the surface of aluminum foil. With a mirror the radiation has to travel through a small layer of glass twice before the mirror is finished with it. Glass is not totally transparent, some light is absorbed so the naked aluminum reflects better.
How does snow affect the earth's albedo?
Albedo means how reflective the earth is. Snow increases the earth's albedo by reflecting more of the sun's radiation.
What is The primary function of the ozone layer?
The Ozone shield protects the earth from much of the Suns harmful radiation.
Why could an increase in greenhouse gases in the atmosphere cause global temperatures to rise?
more heat can be trapped in the atmosphere...
Is the percent of solar radiation reflected by an ocean more than the percent reflected by a desert?
yes
How much of the sun's energy is absorbed or reflected by clouds?
Yes, about 26% of incoming solar radiation is reflected back into space by the clouds and atmosphere.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 would happen if gases absorbs visible light?
Earth's atmosphere does have greenhouse gases. These gases absorb some of the infrared radiation emitted by Earth's surface. If it did not, Earth would grow warmer and warmer as it absorbed more and more solar radiation. Greenhouse gas molecules absorb and emit infrared radiation.
Which biome has the highest net radiation budget value?
It's actually the rain forest because that is the biome closest to the equator, meaning that it has a net radiation budget surplus (more solar radiation is absorbed than reflected/re-emitted as infrared radiation), unlike the biomes closer to the poles which will have a net radiation budget deficit (more infrared radiation is re-emitted/reflected than solar radiation that is absorbed).

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 does A higher albedo mean?
A higher albedo means that more of the incident radiation is reflected, and less of it is absorbed.

Is more energy from the sun absorbed or reflected by Earth's surface?
Absorbed
What happens when the earth's magnetic field turn into 0?
If the Earth were to lose its magnetic field, things would get a lot more interesting. We'd get a lot more ionizing radiation at the surface, which would result in more mutations (and more deaths).
How much of the Sun energy is absorbed by the Earth's surface?
AnswerApproximately 120,000 TW (terrawatts)That is 120000000000000000 joules per second!More energy hits the Earth from the Sun in one hour that the whole world uses all year.(The world uses 15 terrawatts of power per year.)
