When sunlight strikes earth, approximately
a. 30% is reflected back into space
b. 70% is reflected back into space
c. 50% is absorbed by the atmosphere
d. 80% is absorbed by land and oceans

The correct answer is option A

The average albedo of the sunlight is 0.3 which means that of all the sunlight that comes inside the earth, 30% of it is reflected back into the space and only 70% of the(light) sunlight is absorbed.

The sunlight from the sun is absorbed by the various layers of the atmosphere.

The rest is reflected back and in this way the temperature on the earth is maintained.
