Question

Distinguish between the following in not more than 30 words. •Ferrous and non-ferrous minerals •Conventional and non-conventional sources of energy​

Answer 1

Answer:

Ferrous minerals are metallic minerals containing iron. While non-ferrous minerals are also metallic, but they do not contain iron. The difference between these two minerals are tabulated below.

Ferrous minerals Non-ferrous minerals

These minerals mostly contain Iron -These minerals do not contain any iron

These minerals are magnetic- These minerals are not magnetic

These minerals weigh more -These minerals weigh less

Less resistant to corrosion- More resistant to corrosion.

Examples: Manganese and iron -Examples: Gold, copper, zinc, etc.

Conventional sources of energy Non-conventional sources of energy

These sources of energy are also known as a non-renewable source of energy These sources of energy are also known as a renewable source of energy

They find both commercial and industrial purposes They are mainly used for household purposes

These can be considered to be one of the reasons for the cause of pollution These are not responsible for the cause of pollution

Coal, fossil fuels are two examples Wind, solar energy and Biomass two examples

Answer 2

Answer:

Ferrous Metals mostly contain Iron. They have small amounts of other metals or elements added, to give the required properties. Ferrous Metals are magnetic and give little resistance to corrosion. Some examples of the ferrous metals we deal with:

• Vehicle scrap metal
• Demolition Site scrap metal
• Metal offcuts from manufacturing industries

Non-Ferrous Metals do not contain Iron, are not magnetic & are usually more resistant to corrosion than ferrous metals.                                              

Some examples of Non-Ferrous Metals we deal with are:

• Aluminum & Aluminum Alloys
• Copper
• Brass

Conventional sources of energies are the sources of energy which have been used for centuries. For e.g.

•  Fossil fuel energy
• Hydraulic energy
• Nuclear energy

Other than fossil fuels, wood has been a conventional source of energy.

Non Conventional Energy sources are those energy sources which are new and not in common use. But these are renewable and ecologically safe, such as

• tidal power,
• wind power, etc.
