The Mariana Trench is the deepest ocean trench in the world, located in the western Pacific Ocean, east of the Philippines and south of Japan. This crescent-shaped trench is approximately 2,550 kilometers (1,580 miles) long and 69 kilometers (43 miles) wide. The trench’s maximum known depth is the Challenger Deep, which reaches about 10,984 meters (36,037 feet) below sea level, although some measurements have recorded slightly varying depths.
The Mariana Trench is part of the larger global network of mid-ocean ridges and trenches, formed by tectonic activity. It results from the subduction of the Pacific Plate beneath the smaller Mariana Plate. The immense pressure and lack of sunlight in this extreme environment create unique conditions that support specially adapted organisms, including extremophiles and other deep-sea species.
Scientific exploration of the Mariana Trench has been limited due to its depth and the technological challenges involved. However, significant milestones include the 1960 manned descent by the bathyscaphe Trieste, piloted by Jacques Piccard and Don Walsh, and more recent unmanned and manned explorations, such as James Cameron’s solo dive in 2012. These missions have provided valuable insights into the trench’s geology, biology, and potential for new scientific discoveries.

The Indian National Congress (INC) played a pivotal role in India’s freedom struggle from 1885 to 1947, evolving significantly in its strategies over time. Initially, the INC was founded as a platform for educated Indians to voice their grievances to the British authorities, focusing on moderate reforms through petitions and dialogue. Leaders like Dadabhai Naoroji and Gopal Krishna Gokhale advocated for incremental changes and constitutional methods.
The early 20th century saw a shift with the rise of more assertive leaders like Bal Gangadhar Tilak, who promoted the idea of Swaraj (self-rule) and used more radical methods like boycotts and Swadeshi (self-reliance) movements. The INC’s approach further transformed under Mahatma Gandhi’s leadership from 1915. Gandhi introduced non-violent civil disobedience and mass mobilization as core strategies, leading to significant movements such as the Non-Cooperation Movement (1920-22), Civil Disobedience Movement (1930-34), and Quit India Movement (1942).
The INC’s strategies also included negotiations, as seen in the Round Table Conferences and the Cripps Mission. By the 1940s, the INC had successfully galvanized diverse sections of Indian society, creating a broad-based nationalist movement. This evolution from moderate reformism to mass mobilization and civil disobedience was instrumental in undermining British rule and ultimately achieving independence in 1947.
