Answer 1

Answer:

1."Fossils in you Car" this statement tells that the fuels that we use in our vehicle petrol, Diesel and CNG are fossil fuels.

The natural fuels formed from the remains of living organisms buried under the earth long long years ago are called as Fossil Fuels.

2.Anaerobic thermal degradation of wood refers to the process by which wood is burnt in the absence of air. This results into the incomplete combustion of the wood, leaving a residue mostly composed of carbon. This is the process by which char, including coke and charcoal, is made.

3.Yes the petroleum occurs deep inside the earth but yet it floats on water because the density of the petroleum is less than the water therefore it floats in water.

4.Planting trees on large scale helps to reduce pollution caused due to the burning of fossil fuels by absorbing the carbon dioxide released by burning of fossil fuels and in turn replenishing the atmosphere with oxygen. They also trap other pollutants such as dust, ash, smoke and other harmful gases.
