What events occur during high tide

There is decrease in salinity; penetration of light to the water decreases and this is referred to as turbidity, density decreases

Explanation:

The sea is known to contain salty water as water volume increases its saltiness would decrease; the rate at which light penetrates the seas decreases; from normal science, density is Mass divided by Volume and with Mass constant and as Volume increases density is gonna increases.

The tidal force causes Earth-and its water-to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. As the Earth rotates, your region of Earth passes through both of these bulges each day. When you're in one of the bulges, you experience a high tide.
