This half is the inverse half of the first quarter. The final phase is waning crescent. The portion of the moon that was hidden during a waxing gibbous is now visible during a waning crescent. It is barely visible and comes right before the new moon begins once again. The moon has moved farther away from Earth and has slowed its rate of rotation over the billions of years of its existence. The Earth’s gravity drags the moon to rotate in its axis. This is why it rotates only once a month and why the same side of the moon always faces the Earth. Earth’s oceans experience tides every day, two high tides and two low tides. These tides are caused by the moon’s gravitational pull. The moon’s gravitational force will pull on the water in the ocean to form bulges on the sides of the planet lined up with the moon. The pull of the moon will be stronger on the side of Earth nearest to the moon and contrariwise, be weakest on

the side of Earth farthest from the moon. The moon’s gravitational pull also works to stabilize the Earth’s rotation. The Earth wobbles as it spins on its axis. The moons effect limits this wobble to a very small amount. With ought it, the Earth might move almost 90 degrees off its axis. The moon’s craters, light highlands, and maria are what cause the dark and light areas of the moon. Most of the moon’s craters were caused by asteroid collisions. The maria, which are the large dark spots on the moon, is lava that flowed from the moon’s interior, filled the craters, and cooled to solid rock. Highlands are usually about 4 to 5 km (2.5 to 3 miles) above average
