High and Low tides
high tide and low tide occur once a day, we learned in earth science that the moon caused these disturbances in the water, however, after learning about gravitational forces i now understand how they happen in-depth; the moon's gravitational force pulls on water in the oceans so that there are "bulges" in the ocean on both sides of the planet. The moon pulls water toward it, and this causes the bulge toward the moon. The bulge on the side of the Earth opposite the moon is caused by the moon "pulling the Earth away" from the water on that side. thus, we have the tides which most people don't know why they occur.
