The motivation behind the Apollo missions was for the USA to be the first people to land on the moon. Russia had beaten us to outer-space and had put a satellite out in space before us. We wanted to be the first ones to reach the moon and to retrieve new information and data. Scientists needed the help of NASA to answer some important questions and hypotheses. Scientists wanted to know the origin of the moon‚ the temperature history of the moon‚ the cause of mascons‚ and the origin of tektites. Scientists

pockets. As these pockets of magma cool slowly underground‚ the magma becomes igneous rocks. Igneous rocks also form when volcanoes erupt‚ causing the magma to rise above the earths surface‚ above the earths surface magma is called lava. The rocks are formed as the lava cools. Sedimentary rocks are formed at the surface of the Earth‚ either in water or on land. They are layers of fragments of rocks‚ minerals‚ or animal or plant material. Most sedimentary rocks become cemented together by minerals

Mountain ranges are usually segmented by highlands or mountain passes and valleys. •Volcanoes A volcano is an opening‚ or rupture‚ in the surface or crust of the Earth or a planetary mass object‚ which allows hot lava‚ volcanic ash and gases to escape from the magma chamber below the surface. Lava is a hot molten rock or magma that has erupted onto the Earth’s crust. Tephra refers to the airborne matter from a volcanic eruption.

in January 1973‚ the island of Heimaey was the focus of a fissure opening and releasing vast quantities of lava and ash were erupted. As Iceland is a relatively rich country‚ it had the resources to evacuate the nearby port town of Vestmannaeyjar (population 5‚300) in under 7 hours. Furthermore‚ the state had the resources to pump water onto the lava flows‚ solidifying up to 20‚000m3 of lava every hour. This prevented much of the town from being completely destroyed. This shows that in rich countries

population of Kauai is a large amount of not only citizens‚ but vacationers too. Most of the tourism occurs at volcano national parks‚ memorials‚ pearl harbor‚ Napali coast‚ secluded beaches‚ and canyon state parks. The Napali coast is a stretch of black lava shores‚ and is one of the most visited sites in Kauai. The volcano state parks would be cool to visit because they were how Kauai‚ and the other islands of Hawaii‚ formed to begin with. Waimea Canyon is also
