    What technology would a commercial fisherman use to find large schools of fish?

    • Binoculars

    • SCUBA

    • SONAR and satellites

    • Good sense of smell...because naturally that is how you would find a huge school of fish

    Correct Answer
    A. SONAR and satellites
    Explanation
    A commercial fisherman would use SONAR and satellites to find large schools of fish. SONAR technology uses sound waves to detect underwater objects, including fish. It helps fishermen locate and track fish by sending out sound waves and measuring the time it takes for them to bounce back. Satellites, on the other hand, can provide valuable information about ocean currents, water temperature, and other factors that affect fish movement and behavior. By combining these technologies, fishermen can increase their chances of finding and catching large schools of fish.

    _____ refers to the organisms that weren't meant to be caught in the ocean.

    • Oops my bad

    • By-catch

    • Overfishing

    • Aquaculture

    Correct Answer
    A. By-catch
    Explanation
    By-catch refers to the organisms that weren't meant to be caught in the ocean. This term is commonly used in the fishing industry to describe the unintentional capture of non-target species, such as dolphins, turtles, or seabirds, during fishing operations. By-catch can have significant ecological consequences, as it can lead to the decline of vulnerable species and disrupt marine ecosystems. Efforts are being made to reduce by-catch through the use of more selective fishing techniques and gear modifications.

  • 4. 

    _______ is the process of removing salt from ocean water.

    • Desalination

    • Purification

    • Acidification

    • Oxidation

    Correct Answer
    A. Desalination
    Explanation
    Desalination is the process of removing salt from ocean water. It involves the separation of salt and other minerals from the water, making it suitable for various purposes such as drinking, irrigation, and industrial use. This process typically includes methods like reverse osmosis, distillation, or electrodialysis. By removing the salt, desalination helps to provide a freshwater source in areas where water scarcity is a significant issue, especially in coastal regions. It is an essential technique to meet the increasing demand for clean water resources.

    Which of the following is something that the ocean DOESN'T supply us with?

    • Medicine

    • Food

    • Minerals

    • All of the above

    • None of the above

    Correct Answer
    A. None of the above
    Explanation
    The ocean supplies us with medicine through the discovery and extraction of various compounds from marine organisms. It also provides us with food, as it is a major source of seafood for many communities around the world. Additionally, the ocean is a rich source of minerals, including salt, magnesium, and various metals. Therefore, the correct answer is "None of the above" because the ocean supplies us with all of these things.
