The question asks about the fundamental classification of minerals. Minerals are broadly categorized based on their chemical composition and origin into two main types.
A) 2. There are two main kinds of minerals: metallic and non-metallic.
The question asks to identify the type of minerals that contain metal in its raw form. We need to understand the basic classification of minerals based on their composition.
Correct Option: A) Metallic minerals are those that contain metal in their raw form. These are the sources from which metals are extracted.
The question asks to identify a non-metallic mineral from the given options. Minerals are broadly classified into metallic and non-metallic based on their chemical composition and properties. Metallic minerals contain metals in their raw form, while non-metallic minerals do not.
Correct Option: C) Mica is a non-metallic mineral, widely used for its insulating properties in electrical and electronic industries.
The question asks us to identify the correct statement(s) regarding the occurrence of natural resources in India. We need to evaluate each statement individually based on geographical and geological facts.
Gondwana beds are primarily known for their extensive coal deposits in India. While some minor occurrences of natural gas might be associated with coal seams (coalbed methane), the primary and significant reserves of natural gas in India are found in Tertiary sedimentary basins, such as those in the Krishna-Godavari (KG) basin, Mumbai High, Assam, and Rajasthan, which are much younger than the Gondwana formations. Therefore, stating that natural gas occurs in the Gondwana beds in general is incorrect in the context of major reserves.
Koderma, located in Jharkhand, India, is famously known as the "Mica Capital of India." It is a major hub for mica mining and processing, with rich deposits of high-quality mica. This statement is factually correct.
The Dharwar System (or Dharwar Supergroup) refers to ancient metamorphic rock formations in India, primarily found in the Peninsular Shield. These formations are renowned for their metallic mineral deposits, especially iron ore, manganese, gold (e.g., Kolar Gold Fields), and copper. Petroleum (crude oil and natural gas) is typically found in younger sedimentary basins, not in ancient metamorphic Dharwar rocks. Therefore, this statement is incorrect.
B) 2 only. Based on the evaluation, only statement 2 is correct.
The question asks about the applications of Indian Remote Sensing (IRS) satellites. Remote sensing involves acquiring information about an object or phenomenon without making physical contact with it. Satellites equipped with various sensors collect data that can be used for diverse purposes, primarily related to Earth observation and resource management.
A) 1, 2 and 3 only. Based on the analysis, crop productivity assessment, groundwater resource location, and mineral exploration are direct applications of Indian Remote Sensing satellites.
The question asks to identify which of the given minerals is a fossil fuel. To answer this, one needs to understand the definition of a fossil fuel and then classify each option accordingly.
B) Coal — Coal is formed from the decomposition of organic matter (plants) over millions of years under heat and pressure, making it a classic example of a fossil fuel.
