2 (i.c.a.) Tides and Gravity
Tides happen regularly no matter how the wind blows. The daily rise and fall of Earth’s waters on its coastlines are called tides.Tides happen regularly no matter how the wind blows. How can distant objects like the moon and sun influence water on Earth? The answer is gravity. The answer is gravity. As the distance between objects increases, however, gravity’s pull grows weaker.
The moon pulls on the water on the side of Earth closest to it more strongly than it pulls on the center of the Earth. This pull creates a bulge of water, called a tidal bulge, called a tidal bulge, on the side of Earth facing the moon. The water farthest from the moon is “left behind,” forming a second bulge.
In the places where there are tidal bulges, high tide is occurring along the coastlines. In the places between the bulges, low tide is occurring. Earth’s rotation through the tidal bulges causes most coastlines to experience two high tides and two low tides every 25 hours.
