Which of the following is the correct sequence of atmospheric layers from the Earth's surface upwards?
Correct Answer: Option A
Explanation:
The correct order of atmospheric layers from the Earth's surface upwards is Troposphere (0-12 km), Stratosphere (12-50 km), Mesosphere (50-85 km), Thermosphere (85-600 km), and Exosphere (above 600 km).

The albedo of a surface is a measure of its:
Correct Answer: Option A
Explanation:
Albedo is the measure of the reflectivity of a surface. A high albedo means the surface reflects most of the incoming solar radiation (e.g., ice, snow), while a low albedo means it absorbs most (e.g., forests, oceans).

Which of the following surfaces has the highest albedo?
Correct Answer: Option D
Explanation:
Fresh snow has the highest albedo among these surfaces, reflecting about 80-90% of incoming solar radiation. Oceans and forests have low albedo, absorbing most solar energy.

The Earth's atmosphere is heated mainly by:
Correct Answer: Option C
Explanation:
The Earth's atmosphere is mainly heated by longwave terrestrial radiation (infrared radiation) emitted by the Earth's surface after it absorbs solar radiation. The atmosphere is mostly transparent to shortwave solar radiation.

The greenhouse effect is primarily caused by:
Correct Answer: Option B
Explanation:
The greenhouse effect is caused by greenhouse gases (CO2, methane, water vapor, etc.) in the atmosphere that trap outgoing longwave (infrared) radiation, warming the planet.

Which of the following is NOT a greenhouse gas?
Correct Answer: Option A
Explanation:
Nitrogen is not a greenhouse gas. It makes up about 78% of the atmosphere but does not absorb infrared radiation. Carbon dioxide, methane, and nitrous oxide are significant greenhouse gases.

The term 'adiabatic process' in meteorology refers to:
Correct Answer: Option B
Explanation:
An adiabatic process is one in which a parcel of air changes temperature without exchanging heat with its surroundings. As air rises, it expands and cools (adiabatic cooling); as it descends, it compresses and warms (adiabatic warming).

The dry adiabatic lapse rate is approximately:
Correct Answer: Option B
Explanation:
The dry adiabatic lapse rate is approximately 1°C per 100 meters (or 10°C per kilometer). This is the rate at which a dry parcel of air cools as it rises.

The saturated adiabatic lapse rate is:
Correct Answer: Option B
Explanation:
The saturated adiabatic lapse rate (about 0.6°C per 100m) is less than the dry adiabatic lapse rate (about 1°C per 100m). This is because when air is saturated, condensation releases latent heat, which partially offsets the cooling.

A 'temperature inversion' occurs when:
Correct Answer: Option D
Explanation:
A temperature inversion is a reversal of the normal temperature gradient in the troposphere, where temperature increases with altitude instead of decreasing. This traps pollutants and can cause fog and smog.

Which type of rainfall is most common in the equatorial regions?
Correct Answer: Option B
Explanation:
Convectional rainfall is most common in the equatorial regions. The intense heating of the ground causes moist air to rise rapidly, cool, condense, and form heavy afternoon thunderstorms.

What is the major cause of cyclonic rainfall?
Correct Answer: Option B
Explanation:
Cyclonic or frontal rainfall is caused by the convergence of warm and cold air masses. The warm, moist air is forced to rise over the cold, denser air, leading to condensation and precipitation.
