Explanation

Option (a) is correct: Australia holds the world’s largest reserves of uranium, with over 30% of the planet’s identified uranium reserves. According to the World Nuclear Association, Australia’s reserves are estimated to be over 1.7 million tonnes of uranium which makes it the leader in global uranium reserves. Major uranium mining regions in Australia include the Olympic Dam (the world’s largest single deposit of uranium) and the Ranger Mine.

Option (b) is incorrect: Canada has significant uranium re-serves but they are not the largest globally. Canada ranks second in terms of the world’s uranium reserves, with an estimated about 560,000 tonnes. Canada’s most notable uranium deposits are located in the Athabasca Basin in Saskatchewan, which is home to some of the world’s highest-grade uranium deposits.

Option (a), (c) and (d) are incorrect:

The Baltic Sea is located in Northern Europe bordered by countries such as Sweden, Finland, Estonia, Latvia, Lithuania, Poland, and Germany. It is a brackish inland sea and it plays a significant role in regional trade and ecology in Northern Europe. The Black Sea lies to the northeast of Malta, bordered by Turkey, Bulgaria, Romania, Ukraine, and Russia. It is surrounded by countries in Eastern Europe and Western Asia and is important for trade routes, especially for countries like Russia and Ukraine.

It is a cold, productive sea that serves as a major fishing area and an important oil-producing region.

Explanation

The equator is an imaginary line that divides the Earth into two hemispheres: the Northern Hemisphere and the Southern Hemisphere. Singapore is located just north of the equator, at 1° 17 N, making it the closest city to the equator in this list. It is a global financial hub and one of the world’s busiest ports. Its proximity to the equator means that it experiences a tropical rainforest climate characterized by high humidity, heavy rainfall, and consistent temperatures year-round.

Option (a), (b) and (c) are incorrect:

Colombo is situated to the north of the equator, about 7 degrees away. The tropical climate in Colombo means it experiences a warm, humid environment year-round. It is located on the west coast of Sri Lanka and serves as its commercial capital. Jakarta is located at approximately at 6° 9 S latitude and 106° 49 E longitude. It lies just south of the equator, about 6 degrees away. It experiences a warm tropical rainforest climate, with consistent rainfall and temperatures throughout the year. Jakarta is the capital city of Indonesia and one of the largest urban centers in Southeast Asia. Manila is situated at 14 degrees north of the equator. While it is still within the tropical zone, it is farther from the equator compared to Colombo, Jakarta, and Singapore. It is the capital of the Philippines and is located on the western side of Luzon Island which is the largest island in the Philippines.

Explanation

Option (a) is incorrect: The Malacca Strait lies between the Malay Peninsula (in Malaysia) and the Sumatra Island (in Indonesia). It connects the Andaman Sea to the South China Sea and is a crucial shipping route. The Malacca Strait is located around 100°E longitude, which is far to the east of the International Date Line (at 180° longitude). It is relatively far from the IDL compared to the other options.

Option (b) is correct: The Bering Strait is extremely close to the International Date Line. The Bering Strait is located between the Easternmost point of Russia (Chukchi Peninsula) and the Alaskan coast of the United States. It connects the Arctic Ocean with the Bering Sea. The IDL passes through the Bering Strait, making it the closest to the IDL of all the options listed. This proximity means that the time zone on one side of the strait can be almost a full 24 hours ahead or behind the time zone on the other side, depending on the direction of travel.

Option (c) is incorrect: The Strait of Florida lies between Florida (USA) and the Bahamian Islands, connecting the Gulf of Mexico with the Atlantic Ocean. It is located at around 81°W longitude, far to the west of the International Date Line, which places it quite far from the IDL.

Option (d) is incorrect: The Strait of Gibraltar is located between the southern tip of Spain and the northern tip of Morocco, connecting the Atlantic Ocean with the Mediterranean Sea. It is located at about 5°W longitude, much farther west of the Inter-national Date Line.

Explanation

The Strait of Dover is the strait through which the Channel Tunnel (Eurotunnel) connects the United Kingdom and France. The Channel Tunnel, also known as the Eurotunnel, is an underwater rail tunnel that connects Folkestone (UK) with Cal-ais (France) beneath the Strait of Dover in the English Channel. The tunnel is about 50.45 km (31.35 miles) long, with a 37.9 km (23.5 miles) underwater section, making it one of the longest undersea tunnels in the world. Options (a), (b) and (d) are incorrect:

Davis Strait: Located between Greenland and Canada’s Baffin Island, it connects the Labrador Sea to Baffin Bay. Known as the world’s broadest strait, it has depths of 1,000-2,000 meters and fierce tides. It is significant for Arctic navigation and holds potential oil and gas reserves. Denmark Strait: Separating Greenland and Iceland, it connects the Arctic Ocean to the Atlantic. It features the Denmark Strait Cataract, the world’s largest underwater waterfall, formed by cold Arctic water plunging beneath warmer Atlantic water. Strait of Gibraltar: This narrow strait connects the Atlantic Ocean to the Mediterranean Sea, separating Spain and Morocco. At its narrowest, it is 8 miles wide. It is vital for global trade and features unique water flow dynamics due to differing salinity levels.
