The Moon
The Moon, one of the most fascinating creations in earth?s veiw. It is very different and similar to the Earth, and through these questions, the similarities and differences are shown. What are the phases of the Moon, what is the crust made of, what are the rocks on the Moon made of, is there any ice, and is the Moon moving away from the Earth? Although it looks so plain, the Moon is the most studied object in space, and seems to be the most fascinating thing. The Moon orbits around the Earth and that causes phases. This means that the illuminated part of the moon changes. The Moon needs 29.5 days to go from the stages New Moon to another New Moon. However, 2.8 days before that the Moon does a complete orbit around the earth. The Earth will travel 45 million miles until the Moon does a complete orbit around Earth. A New Moon cannot be seen, but a quarter and full Moon can be seen. The reason why a New Moon cannot be seen is because the sun will be behind it and that eliminates the moon from the sky. A strange little phrase is used to describe the ice on the moon, ?Lunar ice.? Kenneth Watson, Bruce C. Murray, and Harrison Brown came up with a very persuading theory t
The lava in the lunar Maria has oozed out of fissures and faults in the ground. It must be very thin to have flowed over such a great distances. The minerals found in the lava are the same as those found in terrestrial basalt: pyroxene, plagioclase, olivine, spinel, and ilmenite. Seven new minerals have also been found, including pyroxferroite and Armalcolite. These lunar basalts contain much more titanium and iron then terrestrial basalt?s and are rich in oxygen compounds. They also do not contain any water. Some of the mountainous highlands on the Moon consist of more than 80% plagioclase. This igneous rock has twice as much calcium and aluminum as the mare basalt?s, but less titanium, magnesium, and iron. Rocks rich in potassium, uranium, and thorium have also been found. These facts are also some of the many differences between the Earth and the Moon. The moon has a very thin crust; it is about 68 km to 107 km thick. Under the crust is a mantle and it could be possible that the moon has a small core. The mantle for the moon is different compared to the Earth?s mantle, the moon?s mantle is only molten, and the Earth?s mantle is hard solid rock, and even the type of rocks in the mantle are different. The moon?s crust is not very similar to the earth but is still classified in the same way. hat there is ice on the moon. The reason for their belie
