Options

B. They alter rainfall and monsoon patterns
C. They cause increased agricultural productivity
D. They have negative impact on agricultural land

Answer

C

Explanation

Aerosol refers to the suspended particulate matter of less than `1mu m` size. These are kind of air pollutants that are suspended in our atmosphere. They have a measurable effect on climate change as they can modify the amount of energy reflected by clouds. As a result, they can change the atmospheric circulation patterns and affect agriculture negatively. These also affect human health by causing breathing problems.
