Explanation: The distribution of natural resources in India is influenced by a variety of factors, including geological, climatic, and geographical conditions. Jharkhand, located in the eastern part of India, is known for its rich coal deposits. This abundance of coal is due to the region's geological history, which includes the presence of coal-forming sedimentary rocks from the Carboniferous period. The coal deposits in Jharkhand are a result of the region's past environmental conditions, which favored the accumulation and preservation of organic matter that eventually transformed into coal.
On the other hand, Kerala, situated in the southwestern part of India, has a very different geological and climatic history. The region is characterized by a tropical climate and a landscape dominated by laterite soils, which are not conducive to the formation of coal deposits. The geological processes that led to the formation of coal in Jharkhand did not occur in Kerala, leading to the absence of coal in this state.
The factors that influence the distribution of natural resources include:
1. **Geology**: The type of rocks and the geological processes that have occurred in a region determine the presence of certain minerals and resources. For example, coal is formed from the remains of ancient plants that were buried and subjected to heat and pressure over millions of years.
2. **Climate**: The climate of a region can affect the type of vegetation and soil conditions, which in turn can influence the presence of certain minerals and resources. For instance, tropical climates can support different types of vegetation compared to temperate climates, leading to different soil compositions and mineral deposits.
3. **Altitude**: The altitude of a region can also play a role in the distribution of natural resources. Higher altitudes can affect the type of vegetation and soil, which can influence the presence of certain minerals and resources.
4. **Human Resource**: While human resource is crucial for the extraction and utilization of natural resources, it is not a direct factor in the natural distribution of resources. The presence of coal in Jharkhand and its absence in Kerala is due to geological and climatic factors, not the human population or workforce.
In conclusion, the unequal distribution of natural resources like coal in India is primarily due to geological and climatic factors, not human resource. Therefore, the correct answer is (B) Human resource, as it is not a direct factor in the natural distribution of resources.
