Animal Transport
Before the wheel was invented, animals were used for
travelling and to carry loads. Even today, animals help
to carry people and goods from one place to another.
Fuel
Cars, scooters, buses, aeroplanes—all vehicles run on fuel like
petrol, diesel, or CNG. As we get energy from food to work and
play, vehicles get energy from these fuels. But fuel comes
from the Earth. And the Earth has limited fuel. It may get over
very soon if we waste it. So we need to use fuel wisely.
Do you Know?
Buses in Delhi run on CNG because it is the
least polluting fuel.
