Question

1. Why are the levels of all the seas equal in the world? 2. How is the sea level measured?​

Answer 1

Answer:

1-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. ... Sea level is measured in relation to the adjacent land.
