GK (Geography)

Equatorial Africa, particularly the Congo River basin, possesses the highest hydro-power potential due to its high rainfall and the significant volume of water flowing through its river systems.

The Great Lakes of North America, ordered from east to west, are Lake Ontario, Lake Erie, Lake Huron, Lake Michigan, and Lake Superior.

Oozes are deep-sea sediments composed of at least 30 percent skeletal remains of microscopic organisms. They are classified as pelagic deposits, which accumulate on the deep ocean floor.

There appears to be a printing error in options 4 and 5, which are identical. Option C shows A-2 (Amazon/Congo for equatorial), B-1 (Mediterranean for dry summer), C-5 (Caspian towards Pamirs for interior lowlands), D-3 (Ecuador/Columbia plateaus for high plateau). The answer key claims this is correct but the list itself has errors.

The Canadian Pacific Railway is a historic transcontinental railway that connects the Atlantic coast at Halifax to the Pacific coast at Vancouver.

Maitri is the name of one of India's permanent research stations located in Antarctica, established in 1989.

Peking (Beijing) is the furthest north and has the lowest average temperature. Tehran is also relatively northern. Canton (Guangzhou) and Singapore are closer to the equator, with Singapore being the closest and thus having the highest average annual temperature.

The tallest trees in the world, such as the Coast Redwood (Sequoia sempervirens), are found in the temperate rainforest biome of the Pacific Northwest.

Temperate regions are associated with Spruce (A-3). Hot deserts are associated with Acacia (B-2). Equatorial regions are associated with Mahogany (C-4). Mediterranean regions are associated with Oak (D-1).

Among the listed countries, the Netherlands has the highest population density, followed by Belgium, the United Kingdom, and Italy.

The cities on the eastern coast of Australia, ordered from north to south, are Cairns, Brisbane, Sydney, and Melbourne.

The Strait of Magellan is located at the southern tip of South America, connecting the Atlantic and Pacific Oceans. A journey along the coast from Chile to Brazil requires navigating around the southern tip of the continent.

Coniferous forests are associated with Spruce (A-1). Tropical rain forests are associated with Rubber (B-2). Tropical deciduous forests are associated with Sal (C-3). Temperate forests are associated with Oak (D-4).

Pechora is a town located in the Komi Republic of Russia, known for its coal industry. Donetsk, Krivoirog, and Zitomir are located in Ukraine.

The natural regions of Brazil, moving from north to south, start with the Amazon basin, followed by the Mato Grosso Plateau, the Brazilian Highlands, and finally the Campos grasslands in the south.

To determine proximity to the equator, we look at the latitudes of these countries. Zambia (approx. 13 degrees S) is closest to the equator, followed by Zimbabwe (approx. 19 degrees S), Botswana (approx. 22 degrees S), and Lesotho (approx. 29 degrees S).

Majuli is primarily threatened by severe riverbank erosion caused by the Brahmaputra river and frequent flooding. Increasing population pressure has also led to land encroachment and deforestation, contributing to its degradation.

Iron ore is famously mined in the Lake Superior region. Coal is heavily associated with the Appalachian/Pennsylvania region. Petroleum is extracted in the Gulf Coastal region. Copper is a major resource in the Arizona region.

Japan's latitudinal sweep and insularity create a varied climate, and it generally lacks a distinct dry season due to consistent precipitation. The east coast is generally warmer than the west coast due to the Kuroshio Current, and Hokkaido is less agriculturally productive than southern regions due to its colder climate.
