Tidal

in #esteem6 years ago

Seawater has its own peculiarities, such as ups and downs, sea tides are a phenomenon of periodic sea level rise and fall caused by a combination of gravitational forces and attractive forces of astronomical objects, especially by the sun, earth and moon. The influence of other celestial bodies can be ignored because the distance is farther or smaller in size itself.

This is because the non-astronomical factors that affect tides, especially in semi-closed waters such as bays, are the shape of the coastline and the base topography of the sea water.
