NIOS Class 10 Science Activity 28.2 Solution | Carbon and its Compounds

In NIOS Class 10 Science Chapter 28- Carbon and its Compounds, Activity 28.2 helps students identify major regions in India rich in coal, petroleum, and natural gas. It also improves map skills by marking these locations.

Carbon and Its Compounds Activity Solution

This activity is based on the NIOS Class 10 science and technology (212) Chapter 28- Carbon and its Compounds Module 6- Natural Resources. Before learning about the distribution of fossil fuels in India, you can also explore activity 28.1, where we compare properties of carbon forms like graphite, coal, and petroleum.

 Aim

To identify and locate major resources of coal, petroleum, and natural gas in India and mark them on the map

Materials Required

i.      Map of India (political map)

ii.   Pencil and eraser

iii.   Atlas/textbook

Procedure

We take a blank outline map of India and use an atlas or a textbook to find the major locations of coal, petroleum, and natural gas in India.

Now we mark these locations on the map using different symbols.

Observation

We observe :

Coal Producing Areas

i.              Jharia (Jharkhand)

ii.          Raniganj( West Bengal)

iii.       Bokaro(Jharkhand)

iv.        Talcher (Odisha)

v.           Kobra (Chattisgargh)

Petroleum Producing Areas

i.              Digboi (Assam)

ii.          Mumbai high(Maharashtra)

iii.       Ankleshwar (Gujarat)

iv.        Nahrkatiya (Assam)

Natural Gas Producing Areas

i.              Krishna- Godavari basin (Andhra Pradesh)

ii.          Mumbai High (Offshore)

iii.       Tripura

iv.        Assam

Explanation

India has rich reserves of fossil fuels like coal, petroleum, and natural gas. These are formed from dead plants and animals over millions of years. They are important energy resources used in industries, transport, and electricity generation.

What is Carbon black?

Carbon black is a fine black powder obtained by heating hydrocarbons in a limited supply of oxygen. This is process is called incomplete combustion.

Uses of Carbon Black

i.     Used as pigment in black inks

ii.   Used in rubber tyres

iii.  Used in paints and printing

Conclusion

We can conclude that:

i.       India has several important regions rich in coal, petroleum, and natural gas.

ii.    These resources are necessary for energy and economic development.

iii.    Carbon black is an important industrial product.
