CUET PG 2025 Environmental Science Questions with Solutions


Question 1.
Acid rain is primarily caused by which type of pollution?
(1) Water pollution
(2) Soil pollution
(3) Noise pollution
(4)  Air pollution
Correct Answer: (4) Air pollution
View Solution

Acid rain occurs due to the presence of sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) in the atmosphere. These pollutants result from industrial emissions, vehicle exhaust, and the burning of fossil fuels. When these gases react with water vapor in the atmosphere, they form sulfuric acid (H₂SO₄) and nitric acid (HNO₃), leading to acid rain.

Minimizing the use of fossil fuels and promoting renewable energy can significantly reduce air pollution and acid rain.

Question 2.
What is the term used to describe pre-monsoon rainfall in Kerala and its neighboring regions?
(1) Blossom rain
(2) Coffee showers
(3) Mango showers
(4) Coconut drizzle

Correct Answer: (3) Mango showers
View Solution

Mango showers are pre-monsoon rainfall that occurs in Kerala and parts of Karnataka. These showers are important as they help in the ripening of mangoes and other fruits, hence the name 'Mango showers'.

Mango showers are also known as 'Blossom showers' in some regions due to their impact on flowering crops.
Question 3. 
In which region is specific humidity recorded as the highest?
(1) Polar region
(2) Temperate region
(3) Equatorial region
(4) Desert region
Correct Answer: (3) Equatorial region
View Solution

Specific humidity is highest in the equatorial region because this area receives maximum solar radiation, resulting in high evaporation rates and increased moisture content in the air.

Regions with high humidity levels often experience tropical rainforests and frequent rainfall.
Question 4.
Which atmospheric wind is commonly referred to as the 'Snow Eater'?
(1) Chinook
(2) Mistral
(3) Bora
(4) Sirocco
Correct Answer: (1) Chinook
View Solution

The Chinook wind is a warm, dry wind that blows down the eastern slopes of the Rocky Mountains in North America. It rapidly melts snow in the region, earning the nickname 'Snow Eater'.

The Chinook wind can raise temperatures by several degrees within hours, creating significant changes in regional weather patterns.
