About 30 percent of the sun's radiation that reaches Earth is reflected back into space by clouds, ice, snow, and other reflective surfaces. This phenomenon, known as albedo, plays a crucial role in regulating the planet's temperature and climate. High albedo surfaces, like polar ice caps, significantly contribute to this reflection, helping to cool the Earth. Understanding albedo is essential for predicting climate change and its impacts on global temperatures.

What reflects the suns radiation back into space?
The Earth's albedo, which is the measure of reflectivity, reflects some of the Sun's radiation back into space. Surfaces such as ice, snow, clouds, and certain types of vegetation contribute to this effect by reflecting sunlight. Additionally, atmospheric particles and gases can scatter sunlight, further aiding in the reflection of solar radiation. Overall, these elements help regulate the planet's temperature and climate.
Most of the solar radiation absorbed by Earth's surface is later radiated back into space as which type of electromagnetic radiation?
Most of the solar radiation absorbed by Earth's surface is later radiated back into space as infrared radiation. This process helps to maintain Earth's energy balance and regulate its temperature.
When solar radiation enters the atmosphere most of the solar radiation is absorbed by the earths surface. However about 6 percent of the solar radiation is blank by the earths surface?
When solar radiation enters the atmosphere, most of it is absorbed by the Earth's surface. However, about 6 percent of the solar radiation is reflected back into space by the Earth's surface. This reflection occurs mainly from surfaces like ice, snow, and water, which have high albedo, meaning they reflect a significant portion of incoming solar energy.
The atmosphere is heated chiefly by radiation emitted by Earth?
The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space. 20 percent is absorbed by clouds and the atmosphere's gases.
What is the ideal radiation budget?
Radiation budget is Earth's atmosphere. The Earth's atmosphere has more solar energy than it radiates back to space.
Earth has a what of about 30 percent reflecting much of the sun's radiation back into space?
Earth has an average albedo of about 30%, meaning it reflects about 30% of the incoming solar radiation back into space. This albedo is influenced by various factors like clouds, ice, and land cover.
About 6 percent of solar radiation is what by the Earth's surface?
About 6 percent of solar radiation is absorbed by the Earth's surface, with the remaining percentage being reflected back into space or absorbed by the atmosphere.
What percent of incoming radiation from the Sun is absorbed by Earth's surface?
Approximately 51% of incoming solar radiation is absorbed by Earth's surface. The rest is reflected back into space or absorbed by the atmosphere.
True or False On avereage clouds reflect more solar radiation back to space than the earths surface?
True. Clouds tend to have a high albedo, reflecting more solar radiation back to space compared to the Earth's surface. This phenomenon contributes to a cooling effect on Earth by reducing the amount of solar energy absorbed by the planet.

What does the earth do with the radiation that reaches us?
Part of the radiation is immediately radiated back into space. The remainder is absorbed; most of what is absorbed will be radiated back into space soon (as the materials heat up, they radiate out more infrared radiation).
What role does radiation play in warming the atmosphere?
Radiation from the sun heats the Earth's surface, which then emits infrared radiation. Greenhouse gases, such as carbon dioxide and water vapor, absorb and trap some of this infrared radiation, preventing it from escaping into space and warming the atmosphere. This process is known as the greenhouse effect.
Why The shiny surfaces reduces heat loss by?
Shiny surfaces reduce heat loss by reflecting thermal energy back into the space, preventing it from escaping. This is because shiny surfaces have low emissivity, meaning they emit less heat through radiation compared to dull surfaces. By reflecting heat back into the space, shiny surfaces help to maintain a warm environment and reduce the energy needed for heating.
What radiation warms the earths surface and the heat energy is radiated back into space?
Infrared radiation from the sun warms the Earth's surface. This heat energy is then radiated back into space as longwave infrared radiation. This process is known as the greenhouse effect.
How much of the incoming solar radiation that reaches the upper atmosphere is immediately reflected back to space?
Six percent is immediately reflected by the atmosphere.(Source: NASA.See the related question below.)
What percent of the solar radiation that arrives at the top of the atmosphere is absorbed by the earth surface?
Approximately 70% of the solar radiation that arrives at the top of the Earth's atmosphere is absorbed by the Earth's surface, while the remaining portion is reflected back into space or absorbed by the atmosphere.
What does it mean to say that the earth has an albedo of 33 percent?
An albedo of 33 percent means that 33 percent of the sunlight that hits the Earth's surface is reflected back into space. This value is a measure of how reflective the planet's surface is. A higher albedo indicates more reflection and less absorption of solar radiation.
