Trivia Questions And Facts Quiz On Oceans!

Explanation
The answer 3.5 represents the salinity level of the oceans. Salinity refers to the concentration of dissolved salts in water, and it is usually measured in parts per thousand (ppt). The average salinity of the oceans is around 3.5 ppt, which means that for every 1,000 grams of seawater, approximately 35 grams are dissolved salts. This salinity level is maintained through various processes such as evaporation, precipitation, and the input of freshwater from rivers.

Explanation
Oceans cover 70% of the Earth's surface. This means that out of the total surface area of the Earth, 70% is covered by water bodies such as oceans. This is a significant percentage and highlights the vastness and importance of the Earth's oceans in terms of global geography and ecosystems.

Explanation
This is a simple representation of a food chain in the ocean. Plankton is at the base of the chain, as it is a primary producer and forms the main food source for many marine organisms. Fish feed on plankton, making them primary consumers. Penguins consume fish, making them secondary consumers. Finally, leopard seals are at the top of the chain as tertiary consumers, feeding on penguins. This food chain demonstrates the flow of energy and nutrients from one organism to another in the ocean ecosystem.

Explanation
The answer provided includes three features found on the ocean floor: the continental slope, continental shelf, and volcanoes. The continental slope refers to the steep slope that separates the continental shelf from the deep ocean floor. The continental shelf is the shallow, submerged extension of a continent that gradually slopes away from the shoreline. Volcanoes can also be found on the ocean floor, formed by volcanic activity and creating underwater mountains.

Explanation
The correct answer is "Giant Krabs & clams also feather worms". This answer suggests that there are three types of creatures that live in the deep ocean: giant krabs, clams, and feather worms. These creatures are adapted to survive in the extreme conditions of the deep ocean, where there is high pressure, low temperatures, and little to no sunlight.
