Algal bloom
Fish migration
Ocean currents Answer: a
Answer is Right!
Answer is Wrong!
The correct answer is: a) Mudbank formation.
The ‘Chakara’ phenomenon is a natural phenomenon that occurs in the backwaters of Kerala, India. It is a circular formation of mud that is caused by the interaction of the tides and the currents. The mudbank is usually formed during the monsoon season, when the water levels are high. The ‘Chakara’ can be several kilometers in diameter and can last for several days.
The ‘Chakara’ is a popular tourist attraction and is often used for fishing. The mudbank is also a breeding ground for fish and other marine life.
The other options are incorrect because:
- Option b) Algal bloom is a rapid increase in the population of algae in a water body. This can cause the water to become discolored and can also produce toxins that can harm fish and other marine life.
- Option c) Fish migration is the movement of fish from one area to another. This can be caused by changes in water temperature, food availability, or other factors.
- Option d) Ocean currents are the large-scale movements of water in the ocean. These currents are caused by the Earth’s rotation and the wind.
