FAQs on Types of Mineral Resources Video Lecture - Social Studies for Grade 4
1. What are the different types of mineral resources? |
|
Ans. The different types of mineral resources include metallic minerals (such as gold, silver, copper), non-metallic minerals (such as limestone, gypsum, salt), fossil fuels (such as coal, oil, natural gas), and renewable energy minerals (such as lithium, cobalt, uranium).
2. How are metallic minerals different from non-metallic minerals? |
|
Ans. Metallic minerals are substances that contain metals in their chemical composition, and they can be extracted to obtain the metal. Non-metallic minerals, on the other hand, do not contain metals and are used for various purposes other than metal extraction, such as construction materials or industrial purposes.
3. What are fossil fuels and why are they important? |
|
Ans. Fossil fuels are natural resources that are formed from the remains of ancient plants and animals. They include coal, oil, and natural gas. Fossil fuels are important because they are widely used as sources of energy for various purposes, including electricity generation, transportation, and heating.
4. What are renewable energy minerals and why are they significant? |
|
Ans. Renewable energy minerals are resources that are used in the production of renewable energy technologies, such as solar panels, wind turbines, and batteries. These minerals, such as lithium, cobalt, and uranium, are significant because they play a crucial role in the transition to clean and sustainable energy sources, reducing the dependence on fossil fuels.
5. How are mineral resources extracted and processed? |
|
Ans. Mineral resources are extracted through various methods, depending on the type of resource and its location. Some common extraction methods include underground mining, open-pit mining, and placer mining. Once extracted, the minerals go through a series of processes, such as crushing, grinding, and refining, to obtain the desired product in a usable form.
