Explanation: Telangana, a state in southern India, has a diverse topography and climatic conditions that influence the distribution of rainfall across its districts. The state experiences a tropical monsoon climate, characterized by distinct wet and dry seasons. The rainfall patterns in Telangana are influenced by the southwest and northeast monsoons, as well as local geographical features such as the Eastern Ghats and the Deccan Plateau.
Khammam, located in the eastern part of Telangana, is known for receiving very little rainfall. This district is situated in a semi-arid region, which means it receives less than 750 mm of rainfall annually. The semi-arid climate is a result of its location and the influence of the Eastern Ghats, which act as a barrier to the monsoon winds, reducing the amount of moisture that reaches the region. This makes Khammam one of the driest districts in Telangana, with limited agricultural productivity compared to other districts that receive more rainfall.
In contrast, districts like Medak, Warangal, and Mahabubnagar receive moderate to high rainfall. Medak and Mahabubnagar typically receive between 750 mm to 1000 mm of rainfall annually, making them more suitable for agriculture. Warangal, located in the central part of the state, receives even higher rainfall, often exceeding 1000 mm annually, due to its location and the influence of the monsoon winds.
Understanding the rainfall patterns in Telangana is crucial for agricultural planning, water resource management, and overall development of the region. The variation in rainfall across districts highlights the need for tailored agricultural practices and water conservation strategies to ensure sustainable development in different parts of the state.
In summary, Khammam is the correct answer as it is the district that receives very little rainfall in Telangana, making it a semi-arid region with distinct climatic and geographical characteristics compared to other districts in the state.
