Question

What are tides and how they're formed​

Answer 1

As research shows, "Tides are very long-period waves that move through the oceans in response to the forces exerted by the moon and sun. Tides originate in the oceans and progress toward the coastlines where they appear as the regular rise and fall of the sea surface."

Answer 2

Answer:

tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the Earth and the Moon.
