Your family is driving across the country to the Grand Canyon. What type of pollution is your car producing?

A. Mobile source

B. Stationary source

C. Agriculture source

D. Natural source

Option A, Mobile source

Explanation:

A mobile source of pollution pollutes the environment while moving. It does not stay at one constant position like a chimney of industry or a stationary machine releasing pollutant gases. Hence, all the moving vehicles, automobiles, diesel engines etc. which release harmful things thereby degrading environment are called mobile source of pollution. Thus, a car releasing pollution while driving through the Grand Canyon will be considered as mobile source of pollution.
