They are controlled by the sun and the moon. Sometimes Earth gets closer to sun because of its elliptic track. When the sun is closer, it's gravity causes a tide on the side closest to the sun and on the opposite side.

Why would it be help to know the times of the tides?

so you dont get stuck out at sea when the tide comes in you dummy


What is the difference between tide and tidal range?

Tide refers to the rising and falling of sea levels caused by gravitational forces of the moon and sun. Tidal range, on the other hand, is the difference in height between consecutive high and low tides at a specific location.


What does the term tide refer to?

A tide is the rise and fall of sea levels caused by the gravitational forces of the moon and sun acting on the Earth's oceans. Tides typically occur twice a day and are influenced by factors such as the moon's phase and the geography of the coastline.


When does a flood tide occur?

'Flood tide' is the expression used for the incoming, or rising tide. The opposite is 'Ebb tide' when it goes back out again. You would have to refer to the tide tables, for the day, in your area of interest. Flood tide is the time between low tide and the next high tide.


Why does the sea rise and fall twice a day?

The sea rise and falls twice a day because of the gravitational force of the moon. in 24 hours the earth rotates 360 degrees. assuming the moon is stationary and I am at one point on the earth at 0.00 hours the sea is half way between high and low tide , the moon having half gravitational effect mid tide at 3.0 hours the moon is in line with me on the earth having high tide. at 6.00 hours the moon is half way round having half effect, mid tide at 9.00 hours the moon is at right angles having full effect, low tide at 12.00 hours the moon is half way round having half effect, mid tide at 15.00 hours the moon is in line having full effect, high tide at 18.00 hours the moon is halfway round having half effect, mid tide at 21..00 hours the moon is at right angles having low tide full effect at 24.00 hours the moon is halfway round having half effect and repeat the next day later, Two high and two low tides per day
