Q1. Critically analyse the strengths and weaknesses of various approaches to sustainable development. Elucidate your answer with suitable examples.

Sediments are small, solid particles that are transported and deposited by wind, water, or ice. These particles can be composed of various materials, including minerals, organic matter, and even fragments of rocks. Sediments can accumulate in different environments such as riverbeds, lakes, oceans, and deserts.

The formation of soils involves a complex set of processes that transform sediments into a medium capable of supporting plant life. Here are the key processes involved in soil formation:

Weathering: This is the process by which rocks and minerals are broken down into smaller particles through physical, chemical, or biological means. Physical weathering includes processes like freeze-thaw cycles, where water freezes in the cracks of rocks and expands, causing the rock to break. Chemical weathering involves the alteration of minerals through reactions with water, air, and other substances. Biological weathering results from the activities of living organisms, such as plant roots exerting pressure on rocks.

Transportation: Once rocks are weathered, the resulting particles or sediments are transported by agents like water, wind, or ice. Water is a particularly effective agent, carrying sediments downstream and depositing them in various locations.

Deposition: Sediments settle and accumulate in new locations through the process of deposition. This can occur when the transporting agents lose their energy and can no longer support the sediment load. Deposition often takes place in areas such as riverbanks, lake bottoms, and floodplains.

Organic Matter Accumulation: Dead plants and animals contribute to the organic matter content of soil. Decomposition by microorganisms breaks down organic materials into humus, which improves soil structure, fertility, and water-holding capacity.

Soil Horizon Development: Over time, distinct layers or horizons develop in the soil profile. The top layer, known as the O horizon, is rich in organic matter. Below it, the A horizon, or topsoil, contains a mix of minerals, organic material, and microorganisms. The B horizon, or subsoil, accumulates leached minerals and materials from above. The C horizon consists of weathered parent material, and the bedrock (unweathered rock) forms the R horizon.

Soil Profile Formation: The combination of weathering, transportation, deposition, and organic matter accumulation leads to the development of a soil profile. This vertical arrangement of soil horizons reflects the history of soil formation in a particular location.

These processes collectively contribute to the creation of a dynamic and evolving soil system, providing the foundation for terrestrial ecosystems and supporting plant growth. Soil properties such as texture, structure, and fertility are influenced by the interactions of these processes over time.

Q2. “We discharge our roles following a particular lifestyle that may not be compatible with sustainable development” Justify the statement with suitable examples from our daily life.

Q3. Describe how traditional knowledge and modern scientific knowledge can be integrated to achieve sustainable development.

Q4. How can sustainable use of natural resources help achieve sustainable development?
