Important Questions (1 Mark): Resources & Development - Class 10 MCQ

In arid soils, the high temperatures destroy decomposers like bacteria, which limits the decomposition of organic matter, resulting in low humus content.

The use of land is primarily determined by physical factors such as topography, climate, and soil types. These factors play a crucial role in dictating how land is utilized for various purposes. For example, the type of soil and climate in a region can influence whether it is suitable for agriculture, while topography can determine its suitability for construction or other activities. Understanding these physical factors is essential for effective land use planning and management.

According to the information provided, land use data is available for 93% of India's total geographical area. This data is crucial for understanding how different regions are utilized and for making informed decisions about land management and development. It is important to note that complete and accurate land use data is essential for sustainable planning and resource management practices.

One of the human activities contributing to land degradation is mining and quarrying. These activities involve the extraction of valuable minerals or other geological materials from the earth, often leading to significant environmental impact. Mining can result in habitat destruction, erosion, and contamination of soil and water sources. Therefore, controlling mining activities is essential in conservation efforts to prevent further land degradation.

1. Planting of shelter belts of plants

These shelter belts help in reducing wind speed, trapping sand, and stabilizing dunes by providing a barrier against wind erosion.

Afforestation, as mentioned, involves planting trees to combat land degradation. Trees play a crucial role in stabilizing soil, preventing erosion, enhancing biodiversity, and mitigating climate change through carbon sequestration. By promoting afforestation initiatives, we can contribute to the conservation and restoration of degraded lands, ensuring their sustainable use for future generations.

The primary reason for the depletion of resources, as mentioned, is the indiscriminate exploitation of resources to satisfy the greed of a few individuals. This has led to major problems such as resource depletion and the division of society into rich and poor. It emphasizes the necessity of adopting sustainable economic development practices to address these issues and ensure the equitable distribution of resources for a sustainable quality of life and global peace.

A crucial step in resource planning, as mentioned, is identifying and documenting available resources across different regions. This process involves activities such as surveying, mapping, and estimating the quantity and quality of resources present in various areas. By understanding and documenting available resources, effective resource planning strategies can be developed to ensure sustainable development and utilization of resources.

Solar energy is a renewable resource because it is continually available and can be harnessed without depleting its source, unlike fossil fuels such as coal, petroleum, and natural gas, which are non-renewable resources.
