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 satellitesExplanation
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.Rate this question:

_____ 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-catchExplanation
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.Rate this question:

_______ is the process of removing salt from ocean water.
-
Desalination
-
Purification
-
Acidification
-
Oxidation
Correct Answer
A. DesalinationExplanation
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.Rate this question:

Human waste, fertilizers, and sewage have created ______ in the ocean.
-
Coral reefs
-
Overfishing
-
Intertidal zones
-
Dead zones
Correct Answer
A. Dead zonesExplanation
Human waste, fertilizers, and sewage contain high levels of nutrients such as nitrogen and phosphorus. When these substances enter the ocean, they can cause excessive growth of algae and other aquatic plants through a process called eutrophication. As these plants die and decompose, they consume oxygen from the water, leading to oxygen depletion in the affected areas. This lack of oxygen creates dead zones, where marine life struggles to survive or cannot survive at all. Therefore, the presence of human waste, fertilizers, and sewage in the ocean can result in the formation of dead zones.Rate this question:
