What does the tide come in mean?

How do you explain tide to a child?

Tides are the rise and fall of water level in the oceans (and lakes, and even in your cup of water, but they’re very small). When the sea level rises to its highest point, we call that high tide. When it falls to its lowest point, that’s called low tide. The rise and fall of the tides is known as the tide cycle.

Why do oceans have tides?

The moon’s gravitational pull on the Earth and the Earth’s rotational force are the two main factors that cause high and low tides. The side of the Earth closest to the Moon experiences the Moon’s pull the strongest, and this causes the seas to rise, creating high tides.

What would happen if there were no tides?

The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.

Definition of tide. (Entry 1 of 3) 1a(1) : the alternate rising and falling of the surface of the ocean and of water bodies (such as gulfs and bays) connected with the ocean that occurs usually twice a day and is the result of differing gravitational forces exerted at different parts of the earth by another body (such as the moon or sun)
