Why is it called low tide?

Why is it called low tide?

Tides originate in the oceans and progress toward the coastlines where they appear as the regular rise and fall of the sea surface. When the highest part, or crest of the wave reaches a particular location, high tide occurs; low tide corresponds to the lowest part of the wave, or its trough.

What happens during low tide?

The regular rise and fall of the ocean’s waters are known as tides. Along coasts, the water slowly rises up over the shore and then slowly falls back again. When the water has risen to its highest level, covering much of the shore, it is at high tide. When the water falls to its lowest level, it is at low tide.

What is high tide mean?

high tide noun (SEA/RIVER) [ C or U ] (also high water) the time when the sea or a river reaches its highest level and comes furthest up the beach or the bank.

How do high and low tides work?
