Advantages of High Tide:
They raise the water level close to the shores and help the ships to arrive at the harbor more easily
. They help in fishing. More fish come closer to the shore during high tides. This helps the fishermen to have a good catch and earn more.
What are the benefits of having tides?
Tides affect other aspects of oceanic life, including the reproductive activities of fish and ocean plants. Floating plants and animals ride the tidal currents between the breeding areas and deeper waters. The tides
help remove pollutants and circulate nutrients ocean plants and animals need to survive
.

What is the difference between tides and waves Class 7?
Tides are the rise and fall of the water on the surface of the sea influenced by the gravitational forces of the Sun, Moon, and Earth. Waves are formed by the
movement
of wind on the surface of the wave and the transfer of energy by the friction between the air and water molecules.
How are tides caused?
The moon’s gravity pulls the ocean toward it during high high tides
. During low high tides, the Earth itself is pulled slightly toward the moon, creating high tides on the opposite side of the planet. Earth’s rotation and the gravitational pull of the sun and moon create tides on our planet.
How many types of tides are there?
