Correct Answer: A
Solution :
Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% in the total amount of ozone in Earth's stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. The latter phenomenon is referred to as the ozone hole. The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be in the absence of its atmosphere. Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects. Albedo or reflection coefficient, derived from Latin albedo "whiteness" (or reflected sunlight) in turn from albus "white", is the diffuse reflectivity or reflecting power of a surface.
