NCERT Solutions for Class 5 EVS Chapter 12

Class 5 EVS Chapter 12 What if it Finishes discusses the careless usage of fossil fuels in the form of petrol, diesel, LPG, CNG, kerosene and its consequences on the earth, if it finishes. The writer is on his way to a school trip to Adalaj Stepwell which is 18 km from Ahmedabad. He has shared his experiences of whatever is seen on the way such as traffic, halt at the petrol pump, the banners and posters at the pump, etc. As the bus stopped in the traffic, it reminded the writer about his father's tractor in the village and its similar smoke. 

What are the different kinds of vehicles? Do all vehicles give out harmful smoke?

Cars, bikes, taxis, scooters, bus, cycles, auto rickshaws, etc. are different kinds of vehicles that run on the road. Not all vehicles release smoke, an exception is a cycle which does not emit any gases. 

How does noise pollution affect humans?

As per the World Health Organization (WHO), after air pollution, noise pollution is the second big menace humans have to face in today's fast life. Sleep disturbance, heart ailments and learning problems in children are caused by extreme exposure to noise pollution. 

At the Petrol Pump

As the bus halted at the petrol pump, many vehicles were waiting for their turn to fill up the tank. Writer and his friends were unable to understand what the poster meant by "Petrol and diesel will not last forever". Abraham, a person working at the petrol pump answered their queries by replying:

  • Petrol and diesel are made underneath the earth which is pumped by big machines and special techniques.

  • It is formed over lakhs of years. Hence, the poster says to use fuels economically and wherever possible, switching off the car engine will save a lot of fuel. Also, it will discourage the pollution caused by running engines at the traffic signals.

The smoke released from burning wood affects health such as causing the cough. As they are poor to afford food, it's even difficult to buy dry wood or any other means of fuel.
