Plate Tectonics‚ Earthquakes‚ and Volcanoes Renee Kuraly 1. There are 13 tectonic plates. (several smaller ones) 2. Evidence for continental drift includes: coastline fit‚ alignment of mountain ranges‚ similar rock sequences‚ fossils‚ modern fauna‚ and ancient climates. 3. We know plate boundaries exist because their defined by earthquake data and the depths of earthquakes show what type of boundary they are. 4. Divergent Boundary- places where plates are moving apart. Convergent Boundary-

Wow… I’m at Yellowstone National Park‚ which was the first national park that was established on March 1‚ 1872‚ by the Yellowstone National Park Protection Act. I can see why Congress thought to establish this park since they hired a professional artist to go and see where they were “helping to save Yellowstone from private development.” As they say in the official National Park Service website‚ "Jackson’s photographs‚ Moran’s paintings‚ and Elliot’s sketches-had caught the imagination of Congress

chamber below the surface. On Earth‚ volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge‚ for example the Mid-Atlantic Ridge‚ has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast‚ volcanoes are not usually created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching

French Canada. In my research I can’t find much information on this encountered expect that these explorers called the Crow beaux hommes or in English; handsome men. In the summer of 1806 the Crow Indians met William Clark’s party exploring the Yellowstone River near Billings‚ Montana. Sadly though‚ they had all of their horses stolen in two nighttime raids. Clark’s party of 12 was bringing back a large group of horses to use for trade at the Mandan Villages in North Dakota. 24 horses were stolen

Volcanoes and Earthquakes test Bew c. 1. Where do earthquakes occur? Earthquakes occur at breaks in the earth’s crust called the fault lines. 2. What causes Earthquakes? Tectonic plates pushing‚ pulling‚ slipping past each other increasing the stress and causes elastic rebound to happen. During elastic rebound‚ energy is released and some travel as seismic waves‚ which cause an earthquake. 3. How do earthquake waves travel and what are the various types of waves? Body waves

Hekla‚ Katla‚ and Laki are located in the south of Iceland. All of them have a distinct personality. Iceland has so many threating volcanoes as a result of its unique location. Iceland lies in the North Atlantic where two of the earth crustal plates are pulled apart. Below Iceland is a hot spot‚ where Molten material rises to Earth’s surface forming active volcanoes. Laki is well known to be a fissure volcano meaning that it erupts in a linear vent system. Laki does not erupt from a single crater

The benefits man can reap from volcanoes are‚ the land around the volcano that erupted would having fertile soil for agriculture‚ it will also have valuable minerals found in the volcanic areas‚ examples are‚ copper‚ gold‚ sliver and more. The tourism rate of the volcanic areas will increase. And‚ there will also be a source of geothermal energy in the volcanic areas. The land around the volcanic areas will have fertile soil that is good for agriculture as‚ when there is a volcano eruption‚

occurred near Musuan volcano in 1976. Biliran is an solfataric active volcano and a volcanic island located in Biliran Province of the Eastern Visayas Region (Region VIII)‚ in Visayasislands group of the central Philippines. It is one of the active volcanoes in the Philippines. Biliran volcano comprises the whole 20x35 km Island of Biliran which is formed by a group of lava domes. It is located across the narrow Biliran Strait from the northern tip of Leyte Island. Biliran volcano is at the northern

If my class received some money for a field trip‚ I would use it to go to Yellowstone. It would be the perfect place for a field trip because we would have oodles of exciting adventures. First of all‚ we would be able to observe many different species of wildlife in their natural habitats. If we were lucky‚ we might discover bears‚ elk‚ buffalos‚ coyotes‚ and maybe even wolves. When I visit the Park‚ I love to find a perch high on a hill and glance across the vast valley at all the animals

DO VOLCANOES HAVE A DESTRUCTIVE POWER AS WELL AS POTENTIAL BENEFIT Volcanoes are usually depicted as towering mountains missing a chunk out of the top from which steam‚ ash and lava spew forth. In reality‚ a volcano is any spot on the surface of the Earth where lava flows. Magma finds its way upwards along fissures or cracks in the planet ’s crust and bursts out onto the surface‚ resulting in a volcano. Magma that flows out of a volcano is called lava. If it comes out of the volcano in an explosive
