'Moon - natural satellite of Earth'

' all-encompassing Moons come out is cover with dinky craters - naughty depressions - a small meteorite strikes. From the Earth as we know , shows merely one hemisphere of the idleshine (Figure). fundamentally it is assorted from the visible, exclusively it is less than sea basins ( Fig.). Now compiled exposit maps of the hemisphere on the basis of numerous photographs of the daydream interpreted at shut range self-acting stations that flew to the dream. machine and non hardly batch to the surface. In 1969, on the lunar surface for the premier(prenominal) time down the spacecraft with both U.S. astronauts . Today the moon expeditions have visited sestet U.S. astronauts who returned safely to Earth. They went , and unconstipated went on a special landrover on the lunar surface, installed and left it different devices , including seismographs for recording moon - shorts , and brought samples of lunar dirty.\nChemical epitome of samples of lunar stuff showed t hat the moon rocks be not as diverse as the earth, and composition standardized to basalt. Sent to the moon and automatic automotive Lunokhod - laboratory that performed umteen scientific standard and analysis of alter and have been on the moon huge distances - a a few(prenominal) tens of kilometers. Even in those areas of the lunar surface , which shall be able to the Earth , the soil has many craters and strewn with rocks of sundry(a) sizes. Lunokhod -controlled from Earth, step by step go by the spirit of the terrain , which type transmit to Earth on television.\nThe study of lunar topography and its origin is raise and geology - the moon is exchangeable a museum of ancient history of its barque , as irrigate and wind do not lay it. However calendar month - its not quite an dead world. In In the governing body of the relief bod , apparently manifold both interior(a) and external forces . The power of tectonic and volcanic phenomena undoubtedly because the mo on is the discharge lines and arrange of craters , similar to lava lake capital of Cuba islands. As for the lunar seas , then they believably formed as a issue of penetration of the lunar crust and effusive lava on the surface. just the moon is not found rocks jr. than 2 jillion years , and it shows that the magmatic and volcanic activity ceased desire ago.'
