Pollutants in Air Study Quiz

What is the primary purpose of using petroleum jelly in the experiment?

• To protect the leaves from sunlight

• To capture suspended particles

• To make the leaves waterproof

• To weigh down the leaves

How are the leaves prepared before exposure to different traffic conditions?

• They are painted with a special dye

• They are dried in the sun

• They are soaked in water

• They are coated with a thin layer of petroleum jelly

What is the significance of selecting different traffic conditions for the experiment?

• To test the durability of the leaves

• To compare the weight of leaves in different climates

• To measure the growth rate of leaves

• To observe the effect of traffic on suspended particles

What conclusion can be drawn from the experiment regarding areas with heavy vehicular traffic?

• They have more suspended particles

• They have no effect on the weight of leaves

• They have the same amount of particles as no traffic areas

• They have fewer suspended particles

What does the experiment suggest about the atmosphere in highly populated areas?

• It is unaffected by industrial emissions

• It has no suspended particles

• It is rich in dust, smoke, and suspended particles

• It is cleaner than rural areas
