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:
<u>Earth's rotation and gravitational attraction of the sun and the moon to some extent are responsible for the motion of tides in the oceans. As the oceans are so vast there exist a cyclic flow water.</u>
Explanation:
- As the earth has its gravity and so does the other phenomenon like stars and moon have there thought this is not felt directly as the tidal bulges that are seen around the earth occur at two times in a day and two times at evening time due to the course of earth rotation having a cyclic time of 12 hours.
- The gravitational pull of the moon is not that strong but since it is close to the earth's surface the tidal bulges are felt on a full moon day and a new moon day as the oceanic currents rise by the gravitational attraction of the moon at night.
- In the day this is noticeable, as the sun has a large attractive force on the planet derives the winds and pressure belts around the globe, When these celestial objects all fall in the same line both ends on earth experience two small and large tidal bulges on east and west sides.
