“Dante’s Peak” demonstrates the volcano as its star, stealing the spotlight from the obstinate grannies, and the romantic relationship between the heroic volcanologist and the town mayor. The film starts by introducing the terror of how destructive, volcanoes can be. There are two main activities that are associated with this eruption, the bombs, and the ash fall. The introduction, transitions to Dante’s Peak, which is a Composite volcano (Stratovolcano). Dante’s Peak starts indicating signs…
Precambrian time covers the tremendous greater part of the Earth's history, beginning with the planet's creation around 4.5 billion years prior and finishing with the development of complex, multi celled life-shapes very nearly four billion years after the fact. The Precambrian is the most punctual of the geologic ages, which are set apart by various layers of sedimentary rock. Set down over a huge number of years, these stone layers contain a lasting record of the Earth's past, including the…
Volcanoes In this documentary, it starts off with the Ring of Fire. This consist of 75% of the world's volcano which is 452. The Ring of Fire is 25,000 miles all around, mostly shaped like a horse shoe. Volcanoes can have different way of how the lava runs. Dr. shows comparing to honey and peanut butter with how the lava can run down the volcano. The lava builds us over the side of the mountain. The doctor also explains that the lava can be very thick that it hold pressure. The pressure…
In 1965, the serpentine rock became California’s state rock; they are abundant in central and northern California. The serpentine rock is a metamorphic rock that forms by the hydration of rocks from the Earth’s mantle; these types of rocks will rise towards the Earth’s surface along fault zones. It can be found in various colors from dark green and brown, to blue with a glossy surface. However, these rocks tend to be slippery and creates a high risk for land slides. Through a series of…
Help!The floor is lava! Being a kid did you ever imagine that the floor was hot, bubbly lava? Well did you ever realize that there is a place on Earth where the floor is actually made of lava? Sounds amazing does it not, well we could visit it we just need your approval. This astounding vista is called Lava Beds National Monument and we should visit it for many reasons. Ok class here you can see the amazing Fern Cave. One reason that we should visit this great wonder is that it will help…
Obsidian can be found in countries where eruptions have occurred such as the United States, Turkey, Scotland, Peru, New Zealand, Mexico, Kenya, Japan, Italy, Iceland, Guatemala, El Salvador, Greece, Georgia, Chile, Canada, Azerbaijan, Armenia, and Argentina. Obsidian is volcanic lava that has cooled and is often referred to as volcanic glass. The name obsidian originated from a Roman named Obsius, a man who discovered a gemstone very similar in nature to obsidian. Its black, glassy, shiny and…
These amazing beautiful towers of volcanoes on the ocean floor vary in every way which only makes them more mysterious and fascinating. The first discovery of a hydrothermal vent was aboard a 3-person submersible named Alvin in 1977 at the Galapagos Rift (WHOI, 2004). This vent was a discovery of warm fluids mixing with cold ocean water rising from the ocean floor crust (WHOI, 2004). “In 1979, a second hydrothermal system was discovered along the East Pacific Rise” (WHOI,2004). This discovery…
Introduction In this paper the Soufriere Hills Volcano will be analyzes in several different parts; an introduction to the Soufriere Hills volcano, the composition of the magma and lava in the volcano, other characteristics of the magma and lava, ash production from eruptions, pyroclastic flows, volcanic activity before the 1995 eruption, the 1995 eruption, cyclic activity within the volcano, and potential hazards of the Soufriere Hills volcano. Soufriere Hills volcano is located in the…
New York exists on bedrock that tells a tale of millions of years ago, going as far back as the late Mesoproterozoic (1.6 to 1 billion years ago). The layers that make up this bedrock show the conditions of the earth’s surface through many different orogenies, which are times of high grade metamorphism and where plate tectonics makes its biggest changes. The Fordham gneiss was formed a billion years ago (oldest) during the Grenville orogeny (Precambrian) which featured sediment deposits and…
New crust is generated as plates pull away from each other and can either cause sea floor spreading or new land to be created. An example of a continental rift valley is the Eastern African Rift Valley which is being formed as the Eastern African plate is moving away from the main Africa plate in a north-easterly direction. Plates move apart due to convection currents in the lithosphere. As the crusts move away from each other the crust thins, tension in the lithosphere causes the plate to…
