Q19: What is air pollution?A: Presence of harmful substances like smoke and gases in the air.
Q20: Name one source of air pollution.A: Vehicle emissions (also industries, burning of fossil fuels).
Effects & Prevention
Q21: One effect of air pollution on health?A: Respiratory problems like asthma.
Q22: How can we reduce air pollution?A: Use public transport, plant trees and reduce burning of fossil fuels.
Q23: What is acid rain?A: Rain containing acidic pollutants from air pollution that harms plants and buildings.
Q24: Why are trees important for air?A: They release oxygen and absorb carbon dioxide.
Q25: What does 'trace gases' mean?A: Gases present in very small amounts in the air, like noble gases and ozone.
Soil
Formation & Types
Q26: How is soil formed?A: By weathering of rocks and decomposition of dead plants and animals.
Q27: Name three types of soil.A: Sandy, clayey and loamy soil.
