According to the article, jellyfish are invading the oceans near JAPAN. Fisherman in the area assert that the amount of fish and jellyfish in the waters have shifted drastically during their lifetime. There is a large abundance of jellyfish (making it difficult or impossible to fish some days) and a small number of other kinds of fish.
Humans may have caused this problem by over-fishing disrupting the balance of the underwater ecosystem. Jellyfish are eaten by some fish and compete with other species of fish. Also humans building docks, bridges, and other water infrastructures have led to a decline in habitat availability for jellyfish.
Answer:
Delta
Explanation:
Delta is a geographical term that describes the formation of wetlands. It is formed from the slow movement of water and deposit from a river into a larger water body. For example lake, sea and ocean. A vivid example is a place where the River Nile moves at a slower pace into the Mediterranean Sea.
Hence, in this case, as a river reaches its mouth it is often affected by incoming tides resulting in a formation called a DELTA.
The different standard times are known as time zones. Time zones are useful because they can allow people to be active during the day and sleep during the night. If people spent hours with sunlight sleeping and worked in the dark, they would likely suffer health problems.
Big countries such as Australia and the United States have many time zones so that people can work and sleep in the time that is adjusted to the hours with sunlight in their specific location.
