Basalt

Texcoc. Their capital is Tenochtitlan. The Tenochtitlan was a large city. One of Aztec emperors his name is Montezuma ll. Aztec culture: In Aztec homes had a steam bath. The Aztec calendar was meant for the sun god. The calendar was made out of basalt, and basalt is solidified lava. The first calendar was called Xiuhpohualli, which counted the years. The calendar helped the farmer with their farming because it also predicted the weather. The second calendar that the Aztecs used was called…

equatorial position and smooth fields of basaltic lavas was ideal for the first manned lunar landing. Mare Tranquillitatis has a diameter of proximally 873km. When view from Earth, it appears dark this is because the crater has been flooded with mare basalts. Mare Crisium (the sea of Crises), a “nectarine basin (about 3.9 billion years old) that spans 740 km” (NASA). Giovanni Riccioli named the Mare Crisium, whose 1651 nomenclature system has become standardized and by the 17 century Mare…

Taupo Volcanic Zone The Taupo Volcanic Zone is a highly active volcanic region situated in the central part of the North Island in New Zealand. The Taupo Volcanic Zone (TVZ) stretches from Ohakune in the south of the Bay of Plenty to White Island in the north. It is estimated that the Earth’s crust below the Taupo Volcanic Zone may possibly be as small as 16 kilometers think and currently moves approximately 8mm per year. The TVZ is named after Lake Taupo, the caldera of the formaly largest…

Justifying Rulership: a comparison of the Olmec and Ubaid cultures There are many similarities in the rise of complex society in both Mesopotamia and Mesoamerica. From monumental structure building to well integrated trade, cultures such as the Olmec of Mesoamerica 1200 BC - 400 AD and the Ubaid of Mesopotamia 4500 BC-3000 BC, have many parallel elements relating to their success as complex societies and what one may refer to as states, despite thousands of years between the two. Comparatively…

Other records of seawater chemistry provide supporting evidence for changes in tectonic activity and enhanced continental weathering during the formation of the Great Unconformity. For example, the average 87Sr/86Sr of sea water increased during the Neoproterozoic (Fig. 4). This long-term signal is attributable to the increasing concentration of 87Sr in continental crust due to the decay of 87Rb, and to the long-term erosion and progressive exposure of 87Sr-rich granitic rocks required to form…

Pennsylvania bluestone, is a type of sandstone taken from quarries in New York and Pennsylvania. The other, known as Shenandoah bluestone, is a limestone found in Virginia's Shenandoah Valley. In Australia and other countries, bluestone refers to a type of Basalt or slate. Fortunately, most of the stones called bluestone are classified as siliceous stones, meaning they are made largely of silicates, and be cleaned using the same method.…

Introduction: The Hawaiian Islands, a popular tourist location due to the inexpensive plane fare from the West Coast, are a convenient vacation get away. When I traveled to the Big Island of Hawaii for a month trip during summer break in July 2013, with my parents, I was able to explore many of Mauna Loa and Kilauea’s volcanic activity, history, and land formations. I also was able to walk out to the lava flowing into the ocean, viewing first hand, that the Big Island is continually expanding.…

OVERVIEW/ OLMEC SETTLEMENT Lines, imagery, figurines, pottery, and statutes; the Olmec Civilization had it all. Art can be infinitely defined. But have you ever heard of the monumental heads of the Olmec Civilization? Allow me to give you a taste of this incredible civilization with hidden treasures it hides within the tropical region of Mexico. Many know of monumental sculptures such as the Easter Island heads and the infamous Stonehenge, but where do these large Olmec heads fit into these…

during the middle Eocene in Europe, particulary Germany. Darwinius masillae was discorvered southeast of Frankfurt, Germany. 3. Darwinius is dated back to approximately 47 million years ago by. The dating technique used was radiometric based on a basalt fragment coming from underlying volcanic chimney. Eosimias are thought to have lived around 40-45 million years ago based on stratigraphic dating (Wright, Simons, Gursky 25) 4. Eosimias exhibit similarities that resemble that of Tarsiers. They…

Volcanoes Volcanoes are magnificent yet dangerous structures created by the forces of nature when Earth’s tectonic plates diverge and collide against each other letting the Earth vent out pent up gases, magma, rock, and ash. There are three types of volcanoes called Shield, Stratovolcanoes, and Cinder cones. Volcanoes are further labeled as active, dormant, or extinct depending on recent activity. The magma underneath the Earth’s mantle is responsible for the explosion and creation of volcanoes…
