Climatology Objective Questions and Answers

Answer: Option [D]

The correct answer is katabatic wind. The cold and dense air blowing down the mountain slope during the night is known as Katabatic wind. Katabatic wind, also called downslope wind, or gravity wind, wind that blows down a slope because of gravity. It occurs at night, when the highlands radiate heat and are cooled.

Answer: Option [C]

Answer: Option [C]

The correct answer is Both I and II.

• It is affected by Earth's rotation and descent of winds from higher altitudes
• It dynamically induced and characterized with anti-cyclonic conditions

Answer: Option [C]

Atmospheric pressure generated on the earth's surface is due to Gravitational force of the Earth. The atmospheric pressure at the surface of the Earth is due to gravitational pull of the earth and is about 14.7 psi. That means that the weight of a column of air which has a cross section of 1 square inch and which stretches from the surface of the Earth to space is 14.7 pounds.

Answer: Option [B]

The correct answer is Carbon-di-oxide. Carbon dioxide is the primary greenhouse gas contributing to recent climate change. Carbon dioxide enters the atmosphere through burning fossil fuels, solid waste, trees, and other biological materials, and as a result of certain chemical reactions, such as cement manufacturing.
