CBSE Questions for Class 10 Geography Minerals And Energy Resources Quiz 1 - MCQExams.com

Limestone is a sedimentary rock (an organic sedimentary rock ). It is composed of calcium carbonate and magnesium or mixture of these two constitutes. From the given options, limestone is a non-metallic mineral.

Iron ore is an example of non-renewable resource. Non-renewable resources are environmental resources that cannot be replenished. Once they have been used up, there will be no more. Most non-renewable resources are minerals, which are mined, for example, gold, iron ore, titanium. Coal and oil are known as fossil fuels and are also non-renewable. 

Tidal energy uses gravitational pull of Earth, moon and sun to produce energy where as a wave energy uses kinetic forces of waves to generate electricity. The tides at shorelines of oceans will rise and fall about twice a day. 

The different types of iron ore consist of rocks and minerals from which iron can be extracted. Iron metal is most often found in the form of hematite and magnetite, though goethite, limonite and siderite types of iron ore are also common.

Bauxite is an ore of aluminium metal. Bauxite ore is the world’s primary source of aluminium. Bauxite is typically found in topsoil located in various tropical and subtropical regions.

Solar energy is the energy derived from sun’s heat and light. It is an important source of renewable energy. Direct Solar energy is used for Water heating, Distillation, Drying, solar thermal energy, solar architecture, molten salt power plants, artificial photosynthesis etc.

• Realizing our potential.
• Earning more money.
• Getting promoted as a recognition of our hard work.
• Getting things done within allotted time.
• Giving us a sense of satisfaction.
• Helping our loved ones by working hard for them.

India’s power sector is huge. It derives its power from diverse sources like hydro power, solar power, bio gas energy, wind power, thermal power, etc. Like all the other states in India, Andhra Pradesh has power generation plants. Andhra Pradesh thermal power plants form an important part of the power generating capacity of Andhra Pradesh. Thermal Power in Andhra Pradesh is mostly generated through gas, coal, and oil. The electric power of the state is generated at the thermal power plants of Andhra Pradesh, which meets the electricity needs of the state.

Following are the thermal power stations of Andhra Pradesh:-

• Ramagundem
  
• Sinhadripuram
  
• Rayalaseema
  
• Vizag
• Kottagundam
• Simhapuri
  
• Sri Damodaram 
  

 Copper:

The orebodies are formed in hydrothermal veins that are born in underground magma chambers far below the deposit itself. The high temperatures of volcanic magma creates hydrothermal veins, allowing some of the heat to escape near the upper layers of the Earth’s crust.

This is why copper is often found in the sedimentary layer, where sand and mud are compressed until they form a layer of sedimentary rock on the surface of the earth. Copper ore gets trapped in oxidized zones within these types of rocks.

 

 

 

Aluminium: 

Element name	Symbol	Percentage by weight of the Earth’s crust
Oxygen	O	47
Silicon	Si	28
Aluminium	Al	8
Iron	Fe	5
Calcium	Ca	3.5
Sodium	Na	3
Potassium	K	2.5
Magnesium	Mg	2
All other elements		1

 

Coal: The plant matter becomes buried, and are no longer exposed to air. Anaerobic bacteria then starts to decompose the material. Burial and accumulation can occur for several thousands of years, producing several meters of partially decayed plant matter known as peat

 

Platinum:

The least reactive metals would be Platinum, Gold, Palladium, Osmium and Silver and in the decreasing order. The inertness of the metals is due to the electron configuration in the orbitals.

 

1. Nonmetallic minerals are a special group of chemical elements from which no new product can be generated if they are melted.
2.  Nonmetallic minerals are, for example, sand, gravel, limestone, clay,graphite.
3. Such materials lack metallic characteristics like good electric and thermic conductivity, luster, rigor, and malleability; they are, however, essential for many industries.
