What are the effects of radiation on different surfaces such as an ice- covered lake, a forest, an ocean, or an asphalt road?

Answers

Answer:

it could kill the fish in water

The effect of radiation on different surfaces will eventually result in the destruction of the habitats and will affect the organisms living at these regions.

What is meant by radiation ?

Radiations are defined as the type of electromagnetic waves or sub-atomic which are emitted as high energy carrying particles.

Here,

The radiations that fall on the different surfaces will affect the climatic conditions over that regions. It varies from the tropical regions to temperate regions.

The earth's average temperature is due to the solar radiations reaching from the sun towards the earth surface.

The surface of earth is regularly cooled due to the presence of the artic and other regions that absorbs less heat and mostly are released back into the space effectively.

The rate of reflection of sunlight by the surface is called Albedo.

But the increased emission of the radiations causes the surface temperature of the earth to a greater extent. This will result in the melting of ice in the colder regions like ice-covered lakes, at a higher rate. Thus the rate of absorption of radiation will be increased in these surfaces.

Also, in the forest and oceans or an asphalt road, the effect of increased radiation reaching these surfaces will lead to a decrease in the albedo effect.

Hence,

The effect of radiation on different surfaces will eventually result in the destruction of the habitats and will affect the organisms living at these regions.
