The moon can be most easily viewed at night, but even sometimes during the day too. The moon rotates once on its axis each time it orbits earth. The moon appearance changes from earth, these changes are called lunar phases. There are 8 lunar phases, it starts with new moon that waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. Those are the 8 lunar phases and they all happen at least once in every month. An eclipse is an event when one object in space casts a shadow onto another, There are two types of eclipses. A lunar eclipse is when the moon moves through earth's shadow. A solar eclipse is when the moon is in between the sun and the earth, so the moon casts a shadow on some part of earth. The umbra of a shadow is the darkest part, the penumbra of a shadow if the lighter part around the umbra of a shadow. An eclipse doesn’t occur every month, thats because the moon is tilted 5° relative to the orbit of earth around the sun. The tilt is enough to place the moon out of earth's shadow so that a lunar eclipse is not able to …show more content…
Tides Are caused by different gravitational forces of the sun and the moon, but the moon is mainly responsible, which is called tidal force. How often tides occur and how tidal levels vary depend on the position of the moon as it orbits the earth. A high tide is when the sea water is above average sea level, and low tides are when the sea level is below average sea level. A tidal range is the difference between the levels of the ocean, the level of ocean is usually compared with the average water levels. Spring tides are the largest tidal range and happen when the sun, moon, and earth from a straight line. Neap tides are the smallest tidal range and occur when the sun, earth, and moon form a 90° angle. The rotation of the earth and moon's revolution around earth determine when tides
