Introduction
A cloudburst is an intense and sudden rainfall event, typically localized to a small area, resulting in heavy downpours within a short period. The rainfall rate during a cloudburst often exceeds 100 mm per hour, sometimes causing flash floods and landslides, especially in hilly or mountainous regions.
Body:
Mechanism of Cloudbursts: Cloudbursts occur when warm, moist air rapidly rises due to convection. As the air ascends, it cools, and the moisture condenses to form clouds. In certain conditions, particularly in regions with steep topography, the clouds are unable to release moisture gradually, leading to the sudden and concentrated release of rain.
Factors contributing to cloudbursts include:
Orographic Lift: In mountainous areas, air masses are forced upwards when they encounter hills or mountains. This increases condensation and can lead to the rapid release of rain.
E.g. Leh cloudburst in 2010
Temperature Differences: Sharp contrasts in temperature can lead to strong upward air currents, which trap moisture in the clouds, eventually leading to a cloudburst.
E.g. In Leh, Ladakh (2022), a cloudburst occurred due to a temperature-induced thunderstorm.
Localized Thunderstorms: Thunderstorms that develop due to intense heating can also trigger cloudbursts, with localized areas experiencing intense downpours.
E.g. In July 2021, a cloudburst near Amarnath Cave in Jammu and Kashmir
Effects of Cloudbursts:
Conclusion
Cloudbursts have become a significant concern in the Indian subcontinent, due to changing climate patterns and increasing human habitation in vulnerable areas and there is a need for robust urban planning and sustainable infrastructure development strategies to minimize damage.

Soil formation is a continuous and complex process that involves several factors working together over time. The key processes involved are:
1. Weathering of Parent Material:
Soil formation begins with the weathering of rocks (parent material) through physical, chemical, and biological processes. Physical weathering breaks rocks into smaller pieces, while chemical weathering alters minerals, and biological weathering involves the action of organisms like plants and microorganisms.
2. Climate Influence:
Climate, particularly temperature and rainfall, plays a significant role in soil formation. High rainfall accelerates weathering and leaching, while temperature influences the rate of chemical reactions. In hot and wet climates, soils tend to be more weathered and leached.
3. Organisms:
Plants, animals, and microorganisms contribute organic matter that enriches the soil, influencing its texture, structure, and fertility. Decomposed organic material forms humus, which improves soil moisture retention and nutrient availability.
4. Topography:
The shape and slope of the land affect water drainage and erosion, influencing soil development. Steep slopes may lead to soil erosion, while flat areas accumulate soil.
5. Time:
Over long periods, soils evolve, and different horizons (layers) develop, contributing to the soil’s profile and fertility.
This process results in a variety of soil types with unique characteristics based on these influencing factors.

Ocean Acidification –
Indian Ministry of Earth Sciences defines Ocean acidification as the decrease in the pH level of the ocean over time, caused by the absorption of excess carbon dioxide (CO2) from the atmosphere. This increase in CO2 reacts with water to form carbonic acid, reducing the pH of the ocean and making it more acidic.
Steps taken to overcome Ocean Acidification –
Implementing these measures requires collective action from governments, industries, civil society, and individuals to mitigate ocean acidification’s impacts.
