Magma

Ancient Italy is known for many different things. It is a peninsula surrounded by the Tyrrhenian, Mediterranean, Adriatic, Ionian, and Ligurian Sea. France, Switzerland, Slovenia, also Croatia borders it. (see appendix A) The Ancient time period lasted from 752 B.C.E to 476 C.E. Pompeii is located in the south west coast of Italy. It had a population of about twenty thousand people. Several interesting things about volcanos and Pompeii include its destruction, the science behind volcanoes, the

a decay product of 87-rubidium, to 86-strontium is approximately .7025. However, in hotspots, this ratio is substantially greater, averaging .7038. These two ratios cannot be equated by natural variation – the difference is too large. Instead, the magma resulting in each feature likely emerges from a different geochemical reservoir, and thus possesses a distinct geochemical signature. Another confounding factor is the existence of linear intraplate oceanic ridges. In 1963, Dr. John Wilson established

Toothpaste experiment for being big and foamy. Ketchup and Vinegar - Like Real Lava - The classic Science Fair Volcano with ketchup red foul smelling fake magma falling out the side of the volcano. Mentos and Soda - Like a Hot Spring - This is the classic Soda experiment in a volcano representing how a volcano's top falls off when the Magma forcefully pushes on rock breaking out of the volcano like a hot spring. Dry Ice Volcano - Smokey Reaction - This is the slowest chemical reaction for slowly

This story is all about Obsidian Susan. She was a shiny, black rock called obsidian. Obsidian Susan was an igneous rock because she was formed by being exploded out of a volcano as magma. Then, she cooled into rock. She is a pretty rock but she was not like the others. The other rocks had shiny white crystals that glimmered in the sun. Obsidian Susan thought they all looked beautiful except her. What Obsidian Susan really wanted was to look like Ariel Marble. She was the prettiest, shiniest rock

erosion, and the rock cycle. Igneous rock has an effect on how the Grand Canyon changed over time. First, Igneous rock is “cooling magma below ground and cooling lava above ground” (26). This shows that, if igneous rock is formed on the earth's surface, it can be found in the Grand Canyon as more rock layers are exposed by erosion. Next, Intrusive igneous rock forms when “Magma pushes or intrudes into the rock below the Earth’s surface and cools”(26). Also,“Extrusive igneous rock forms when lava erupts”(26)

more year for the roots to break through the the lava or the magma. After the eruption there were still major things that had to be fixed.

the ADI silica lab, we were asked the question “Which “magma” leads to more explosive eruptions and is potentially more dangerous to humans?” . We would soon experiment with “silica” and liquid to determine how the silica content affects its viscosity and relates to potential dangers of a volcanic eruptions. For this experiment to be successful, you must know some key background information. Silica is a solid compound which is present in magma and influences its properties, viscosity is what we call

of quartz grains. These grains came from sedimentary rocks underlying the volcano, e.g. the Dakota Sandstone. The earliest stage of this phase, Mud Hill, formed during a phreatomagmatic eruption, which means that it was driven by the interaction of magma and water, followed by basalt flows. That was approximately 1.7 million 30,000 years ago. The First Series lava flows happened simultaneously as the cinder cone was forming. They flowed east, originating from fissures or series of small vents. The

the Earth’s mantle from which heat rises through the process of convection. This heat facilitates the melting of rock at the base of the lithosphere, where the brittle, upper portion of the mantle meets the Earth’s crust. The melted rock, known as magma, often pushes through cracks in the crust to form volcanoes. Hot spot volcanism is unique because it does not occur at the boundaries of Earth’s tectonic plates, where all other volcanism occurs. Instead it occurs at abnormally hot centers known as

Me and My Volcano Volcanoes exist all around the world.A volcano is a place where hot ash,gases,and molten rock deep underground erupt. Volcanoes can be dangerous for many reasons for example hot ash,lava,cinders,and mud. The magma chamber carries magma up into the pipe and out the crater or top vent. Volcanic eruptions can differ in their violence for example some volcanoes are fast moving lava or pahoehoe or slow moving lava aa. Some volcanoes erupt water vapor carbon dioxide and some volcanoes
