PPT-Volcanoes By: Emily Bach and Meg Curi

Cause most volcanoes are formed when two of Earths plate collide the collision drives one of the plates under another the plate that is under the other one begins to meltgtthis melted rock is known as magma. Yellowstone Park is not only spectacular but also unique. It is the result of three volcanic eruptions, the likes of which have never been seen in all of recorded history. The first eruption occurred 2 million years, followed by two more eruptions 1 million years and 600,000 years ago. Below Yellowstone Park there is a hot spot that is generating basaltic magma. At the time of each of their three eruptions, the magma chamber began to produce large volumes of basaltic magma. Because of its low viscosity, the basaltic magma quickly rose to the bottom of the granitic continental crust. However, because the density of basaltic magma (density about 3) is slightly higher than that of granite (density about 2.9) it could not force its way through the granite to the surface. Instead, it began to pool beneath the granitic crust. The amount of heat trapped within the molten basaltic magma was enough to melt the minerals making up the overlaying and surrounding granite, forming a growing mass of granitic magma. Granitic magma is highly viscous and extremely gas-charged. Although it rose only very slowly, the granitic magma advanced upwards by melting even more of its own overlying granitic rock. At some point, radial fractures began to form around the rising mass of granitic magma. These fractures allowed steam eruptions to vent gas. Shortly after, with the overlying granitic rock severely weakened by the fractures, the highly gas-charged granitic magma erupted. The land to a distance of 200 miles in all directions was decimated. Pyroclastic flows, the most destructive eruptive features known, swept across the countryside. Ash fell across the country from the eruption site to the Atlantic Ocean. Ash polluted the world’s atmosphere, blocked the energy of the Sun, and plunged the Northern Hemisphere into a frozen wasteland for years. Can such an eruption occur in the Yellowstone region again? All the evidence suggests that the magma chamber below Yellowstone Park is current rising. According to the director of the Yellowstone Volcanic Observatory, it is not a question of whether or not another super-eruption CAN happen; it’s a question of WHEN it will happen!.

Johann Sebastian Bach was born on March 21st l685, the son of Johann Ambrosias, court trumpeter for the Duke of Eisenach and director of the musicians of the town of Eisenach in Thuringia. . What is a Volcano. Volcano: a weak spot in the crust where molten rock (magma) comes to the surface. Most volcanoes are located around subduction zones and hot spots. Over 75% of worlds volcanoes are found . Romans believed in Vulcan, their god of fire.. They thought that Vulcan worked at a hot forge, striking sparks as he made swords and armor for the other gods.. Hawaiians told legends of the wanderings of Pele, their goddess of fire.. Compare the features of volcanoes.. Describe the stages in volcano formation.. What are Volcanoes?. Volcanoes are vents through which molten rock and gas escape from a . magma chamber.. Volcanoes can differ. The term 'cantata', invented in Italy in the 17th century, refers to a piece of music written for voice or voices . (. cantare. ) and . instruments. . By Bach's time (1685-1750), cantatas were generally works that contained several movements or distinct sections with tempo and key changes.. Volcanoes.
