Question

1. Why are the levels of all the seas equal in the world?​

Answer 1

Answer:

Because the ocean is one continuous body of water, its surface tends to seek the same level throughout the world. However, winds, currents, river discharges, and variations in gravity and temperature prevent the sea surface from being truly level.

Answer 2

Like water level in a swimming pool is equal everywhere, similarly consider seas as a large swimming pool
