74. Lake Natron, that was recently in news, is located on the border between which two countries?
[A] Kenya and Uganda
[B] Tanzania and Kenya
[C] Ethiopia and Kenya
[D] Tanzania and Mozambique
Show Answer
Correct Answer: B [Tanzania and Kenya]
Notes:
Recently, Tanzania stopped a large-scale soda ash mining project at Lake Natron to protect its ecosystem. Lake Natron is a salt lake on the Tanzania–Kenya border, part of the Great Rift Valley. It was designated as a Ramsar Site of International Importance in 2001. It is the only reliable breeding ground for Lesser Flamingos in Africa, hosting 75% of the world’s population. The proposed mining project by Ngaresero Valley Company threatened flamingos, fragile hydrology, and the livelihoods of 65,000 Maasai pastoralists. Government allowed only small-scale traditional soda ash collection and emphasized sustainable ecotourism as the future.
75. Hunga Tonga Volcano, that was recently seen in news, is located in which ocean?
[A] Arctic Ocean
[B] Indian Ocean
[C] Southern Pacific Ocean
[D] Northern Atlantic Ocean
Show Answer
Correct Answer: C [Southern Pacific Ocean]
Notes:
A collaborative research team led by University of Tasmania scientists completed a 54-day voyage on CSIRO research vessel (RV) Investigator to study the 2022 Hunga Volcano eruption in Tonga. It is a submarine stratovolcano in the Tongan archipelago, southern Pacific Ocean. The volcano has erupted regularly over past decades. On January 15, 2022, it had an explosive eruption, one of the largest of the 21st century. The eruption sent volcanic plume into the stratosphere, triggered shock waves, and caused tsunami waves across ocean basins. The voyage collected data to understand volcanic impacts, seafloor changes, and tsunami risks, aiding Pacific disaster preparedness.

The Mar del Plata Canyon lies 250–300 km off Buenos Aires Province and is one of Argentina’s largest submarine canyons. It has fine sandy sediments mixed with terrigenous material and planktonic foraminifera. The region is highly productive due to the Argentine Shelf-break Front, where subantarctic waters meet the Falkland-Malvinas Current. A submarine canyon is a steep underwater valley cutting into continental slopes and shelves.
