Question

about 40% of the radiation coming from the sun is returned by scattering from earths atmosphere. this is measured by a
a. coercivity.
b. refractivity.
c. scattering coefficient.
d. albedo.

Explanation:

Albedo is the measure of the reflectivity of a surface. It represents the fraction of solar radiation that is reflected back into space. In the context of Earth's atmosphere, albedo plays a crucial role in the planet's energy balance. A higher albedo means more radiation is reflected, leading to a cooler surface, while a lower albedo means more radiation is absorbed, resulting in a warmer surface.

Answer:

d. albedo.
