World Geographical Records

Buenos Aires is the largest and most important port in Argentina, handling both cargo and passenger traffic. It serves as the country's primary maritime gateway for international trade.

Vostok Station in Antarctica recorded the world's coldest temperature at -89.2°C (-128.6°F) on July 21, 1983. This Russian research station sits on the Antarctic ice sheet at an elevation of 3,488 meters. Verkhoyansk in Russia also experiences extreme cold, Ust' Shchugor is in Russia, and Snag is in Canada, but none have matched Vostok's record.

 A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice.Around 70% of the fresh water on Earth is contained in this ice sheet.

Lake Superior is the largest freshwater lake in the world by surface area, spanning approximately 82,100 square kilometers. It is located on the border between the United States and Canada and forms part of the Great Lakes system. Badkal Lake is a smaller lake in Odisha, India, while Wullar Lake is in Jammu and Kashmir and is one of India's largest freshwater lakes.

The Southern Hemisphere is called the water hemisphere because it has a much larger proportion of water surface compared to land. About 80% of the Southern Hemisphere is covered by oceans, while the Northern Hemisphere has more landmass with continents like Asia, Europe, and North America.

The atmosphere (air) is the largest nitrogen reservoir, containing approximately 78% nitrogen gas (N2) by volume. This represents about 4×10^21 tons of nitrogen. While soil contains nitrogen in organic and inorganic forms, and the sea contains dissolved nitrogen, neither compares to the massive atmospheric reservoir. Rocks contain minimal nitrogen.

Correct Answer: Mississippi River System

Marine ecosystems cover about 71% of Earth's surface, making them the largest ecosystem by area. This includes all oceans and seas, which far exceed the total area of all terrestrial ecosystems combined - deserts cover about 33%, mountains about 25%, and other land ecosystems the remainder.

Barents Strait lies between the Scandinavian countries and the Arctic Ocean.

 Persian Gulf and Gulf of Oman

The Strait of Malacca is a narrow stretch of water located between the Malay Peninsula (mainland Malaysia) and the Indonesian island of Sumatra. It serves as a critical shipping lane connecting the Indian Ocean to the South China Sea. The other options pair different Indonesian islands incorrectly.

The Indian Ocean is indeed warmer than both the Atlantic and Pacific oceans in northern and southern hemispheres due to its location between warm land masses. Among major oceans, the Atlantic is the coldest in the equatorial region because of upwelling and circulation patterns. However, the Pacific's average surface temperature is NOT higher than the Atlantic's in the southern hemisphere - the Atlantic is actually warmer there. Therefore, only statements 1 and 3 are correct.

Agulhas Current is the major warm current in the Indian Ocean.

Option (3) is the correct answer.
