College Chemistry 1 Lab 16 Oxidation Reduction Lab 16 Introduction: I will learn about redox reactions. Materials and Methods: I placed ten drops of each substance into different wells. Then I took Magnesium and put it in the first one. I put Zinc into the second one. I placed lead into the third and fourth one‚ and put iron into the fifth one. Results: See Table Below. Discussion: I learned about different redox reactions. Questions: A. Sodium

It’s current eruption started in January 1983‚ and there is no signs that the current eruption is slowing or will come to an end anytime soon.

But the classic eruption – cone-shaped mountain‚ big bang‚ mushroom cloud and surges of molten lava – is only a tiny part of a global story. Volcanism‚ the name given to volcanic processes‚ really has shaped the world. Eruptions have rifted continents‚ raised mountain chains‚ constructed islands and shaped the topography of the earth.

A further summit eruption occurred on August 10‚ 2008.[7] Starting in January 2011‚ the volcano is weakly erupting and may be building up to a larger hazardous eruption. The most destructive eruption of Mayon occurred on February 1‚ 1814. Lava flowed but not as much compared to the 1766 eruption. Instead‚ the

partial melting of the plate‚ this is similar to composite and calderas as O-O convergence is destructive along with calderas and composite. They tend to have gentle and predictable eruptions which can cause to build up a large amount of flows‚ where the lava is of low viscosity and is basaltic causing it to be 1200°C. Furthermore‚ fissure volcanoes tend to also have gentle and predictable eruptions along with shield volcanoes and are found at constructive margins and rifts. As the North American and Eurasian

Analyse the factors that cause differences in the hazards caused by volcanoes around the world (40 marks) A hazard is defined as something which has the potential to kill or cause harm. However a hazard is only a risk to people if they are exposed to it. This is when a hazard can cause disasters. For example‚ a volcano is only a hazard if the population comes in contact with the consequences of its activity. Hazards and their likeliness to become disasters can depend on many different factors‚ for

Alyssa Iferenta A volcano is an opening in the earth’s crust were magma from deep inside the earth forces its way to the surface. Once the volcano erupts the magma is called lava. Volcanic eruptions have positive and negative effects. For example the lava flow can cause complete chaocs and dismantle villages‚ but once the lava decompses it create extermely fertile soil. Volcanic eruptions throughout history have been known to cause mass destruction from lahars. [Refer to figure 1] A lahar is a

We know the earth’s core is hot through hot spring geezers and volcano lava. 2 types of crust OCEANIC CRUST: it is found under the oceans; it’s thin and has a low density as it is made from an igneous rock called basalt. It is 6-8 km thick. CONTINENTAL CRUST: this forms the land‚ made from granite which is low density igneous
