Question

How are the tides caused?

Answer 1

Hint: The usual rise and fall of the ocean’s waters are known as tides. It is high tide when water encloses much of the shore by rising to its highest level and low tide when water falls to its shortest level and recedes from the shore.

Complete Step by Step Answer:
Forces that cause tides are called tidal constituents. The Earth’s rotation is a tidal constituent and the primary tidal constituent is the moon’s gravitational pull on the Earth.
The closer objects are, the greater the gravitational force is between them. Although the sun and moon both exert a gravitational force on the Earth, the moon’s pull is stronger because the moon is much nearer to the Earth than the sun. The moon’s tidal force has a much greater effect on the ocean. Water is liquid and can react to gravity more dramatically.

The moon’s ability to raise tides on the Earth is an example of a tidal force. The moon exerts a tidal force on the whole planet. This has little effect on Earth’s land surfaces because they are less adaptable. Terrestrial tides can alter an object’s precise location. Terrestrial tides are significant for radio astronomy and calculating coordinates on a global positioning system (GPS).

Note: A tidal wave or tsunami, for example, makes use of the word ‘tide’ and exhibits rise and fall of water levels. However, this event is induced wholly by a displacement of a huge amount of water due to earthquakes, volcanic eruptions, underwater outbreaks, and others. All these factors take place on the Earth’s surface and have nothing to do with the moon or sun.
