World Oceans Day Quiz: Questions With Answers

The Pacific Ocean is the correct answer because it is the deepest ocean in the world. It has an average depth of about 12,080 feet (3,682 meters) and reaches its maximum depth in the Mariana Trench, which is approximately 36,070 feet (10,972 meters) deep. The other oceans listed, Indian Ocean, Atlantic Ocean, and Arctic Ocean, do not have depths as significant as the Pacific Ocean.

Approximately 70% of Earth's water is covered by the oceans. This is a well-known fact supported by scientific research and observations. The vastness of the oceans and their deep waters contribute to this significant percentage. The remaining water is found in various forms such as ice caps, glaciers, rivers, lakes, and underground water sources. The oceans play a crucial role in regulating the Earth's climate, supporting marine life, and influencing weather patterns.

The correct answer is "All of the above" because all three options - overfishing, plastic pollution, and oil spills - pose significant threats to oceans. Overfishing depletes fish populations and disrupts the marine ecosystem. Plastic pollution, including microplastics, harms marine life and pollutes the water. Oil spills have devastating effects on marine habitats, causing long-term damage to ecosystems and killing marine organisms. Therefore, all three factors contribute to the grave threat faced by oceans.

The correct answer is the Arctic Ocean. The Arctic Ocean surrounds the North Pole. It is the smallest and shallowest of the world's five oceans. It is located in the Arctic region and is mostly covered in ice throughout the year. The Arctic Ocean is known for its unique ecosystem and is home to various species of marine life, including polar bears, seals, and whales.

The theme of the 1st World Oceans Day was "Our Ocean, Our Responsibility." This theme emphasizes the importance of taking care of our oceans and recognizing that we all have a responsibility to protect and preserve them. It highlights the need for individuals, communities, and governments to work together to address the challenges facing our oceans and ensure their sustainability for future generations.

Ocean acidification refers to the process of decreasing the pH of the Earth's ocean. This occurs when carbon dioxide is absorbed by seawater, leading to a decrease in the ocean's pH level. As the pH decreases, the water becomes more acidic, which can have detrimental effects on marine life and ecosystems.

SDG 14, also known as Sustainable Development Goal 14, focuses on "conservation and sustainable use of the oceans." This goal aims to protect and restore the health and productivity of oceans and marine resources, while also promoting sustainable fishing practices and marine biodiversity. It addresses issues such as pollution, overfishing, and ocean acidification. By choosing SDG 14 as the correct answer, it indicates that this specific goal is the one that specifically addresses the conservation and sustainable use of oceans.

The correct answer is 2008. The United Nations officially recognized World Ocean Day in 2008.

The theme of the 2023 World Ocean Day is "Planet Ocean: Tides are Changing". This theme suggests that there are significant shifts and transformations happening in the world's oceans. It highlights the need to address and adapt to these changes in order to protect and sustain our oceans. The theme also emphasizes the importance of collective action and collaboration to bring about positive change for the ocean and its ecosystems.

The concept of World Ocean Day was first proposed by Canada.
