🪨 What are Minerals?

Minerals are natural substances that have a definite chemical composition.

👉 Hindi Explanation:
Minerals prakritik padarth hote hain jinmein nishchit rasayanik sanrachna hoti hai.

🗺️ Types of Minerals

1. Metallic Minerals – Contain metals
   
   

   • Example: Iron ore, Bauxite
     
     

2. Non-Metallic Minerals – Do not contain metals
   
   

   • Example: Limestone, Mica
     
     

3. Energy Minerals – Used for producing energy
   
   

   • Example: Coal, Petroleum
     
     

👉 Hindi Explanation:
Metallic minerals mein loha, tamba jaise dhatu hote hain. Non-metallic mein aise padarth hote hain jinmein dhatu nahi hoti jaise limestone. Energy minerals se urja milti hai jaise koyla, tel.

⛏️ Mode of Occurrence of Minerals

1. In veins and lodes – Formed by cooling of magma
   
   

   • Example: Gold, Silver
     
     

2. In sedimentary rocks – Formed by deposition
   
   

   • Example: Limestone
     
     

3. Near surface/Alluvial deposits – In sands and river beds
   
   

   • Example: Tin, Platinum

⚡ Energy Resources

🔋 Conventional Sources

1. Coal – Most abundant, used in thermal plants
   
   

2. Petroleum – Found in Assam, Gujarat, Mumbai High
   
   

3. Natural Gas – Less pollution, used in vehicles
   
   

👉 Hindi: Paramparik urja ke srot mein koyla, petrol, aur prakritik gas aate hain.

⚡ Non-Conventional Sources

1. Solar Energy – From sunlight
   
   

2. Wind Energy – Tamil Nadu, Gujarat
   
   

3. Biogas – From animal and plant waste
   
   

4. Tidal and Geothermal – Still developing
   
   

👉 Hindi: Aparparik urja jaise solar, wind, biogas prakritik aur saf sutri hoti hai.

✅ Need for Conservation

• Minerals are non-renewable
  
  

• Need to reduce, reuse, and recycle
  
  

• Promote energy saving and eco-friendly sources
  
  

👉 Hindi: Khanij seemit hote hain, inhe bachane ke liye unka punarupayog aur sahi istemal zaroori hai.
