Magma

Explanation/Essay There are many different types of volcanos on Earth. All of these volcanoes have differing characteristics and features. Three types of volcanoes are Cinder Cone, Shield and Composite. One type of volcano that is quite common around the world is the Cinder Cone volcano. Cinder cone volcanoes are in the shape of a cone, hence their name. It is made of piles of lava and not ash. During cinder cone volcano eruptions blobs of lava (”cinders”) are blown into the air and around

Volcanoes exist all around the world. A volcano is where ash, gases, and molten rock from 30-120 feet underground erupts onto the surface. The ash, gases, and molten rock all stay in something inside a volcano called a magma chamber. The larger the eruption the more gas the magma has. The gases include water vapor, carbon dioxide, and sulfur dioxide. The two types of lava are aa (ah-ah) and pahoehoe. The types of volcanoes are shield, strato, silicic caldera complexes, monogenetic fields, mid-ocean

New Jersey's Mountain - Mac-Mount Laurel This landform is Mt. Laurel's biggest mountain it is fun to climb . This landform was created because the plates sliding , which then bumped into each other which made the plates go up, which made the mountain . then it kept on going . But then, water erosion cut some of the mountain off. This is a great place to visit because it's easy to climb and then once you're at the top you can see the great view of New Jersey. Then you can see actual fossils in the

Although convection current in the earth layer are closely associated with the movements of the tectonic plates they also play a role in the formation of rocks, such as the igneous and metamorphic rocks. Igneous rocks form through the solidification of magma or lava. This can occur in two different places, on earth surface and under earth surface. Rocks that form on earth surface are called extrusive, rocks that form under earth's surface are intrusive plutonic rocks. A Metamorphic rock is formed when

volcanoes. A volcano, which is defined as a “vent or chimney which transfers molten rock known as magma from depth to the Earth’s surface” by Geoscience Australia(2015), can be considered to be a cloud with a silver lining for society due to their eruptions. Attributed to factors such as density and pressure, volcanic eruptions occur for several reasons. Grotzinger and Jordan(2014) explains that as magma is less dense than solid rock it will rise buoyantly through the lithosphere finding its way to

interior of the earth to the surface. There are more than three places this hot mantle can go. It can go to a mid-ocean ridge to make new crust, go into a magma chamber, that in special conditions to form igneous rocks. Throughout the rest of this essay, I will go into detail on how magma and lava can form igneous or metamorphic rocks. A magma chamber is a large underground pool of liquid rock found beneath the surface of the Earth. The molten rock in such a chamber is under great pressure, and when

Cinder Cone, Shield, Composite Volcanoes Volcanoes are a big mound that erupts and spews out lava, when it erupts the lava flows down the side of the volcano and when it cools down it turns to rock. As it erupts rocks fly out and can cause a huge amount of damage and quite often kill people. When volcanoes erupt they create a large ash cloud. There are three

Volcan, named after the Vulcan god of Greek mythology, is a geological structure by which magma emerges in the form of lava, volcanic ash and gases from the interior of the earth. When the magma rises there is an episode of violent activity called eruption, which can vary in intensity. The duration and frequency ranges from mild lava flows to extremely destructive exposures. Volcanoes are mountain shaped with a crater on top. Volcanoes not only exist on Earth, but also on the sea, other planets and

that question for years now. There’s thousands of volcanos, we don’t even know about, like the ones on the ocean floor that we aren’t even mindful of them erupting. The only thing scientists are aware of now that there are “at least 1000 identified magma systems” (Simkin & Siebert 27). Now the real question is, how do these volcanoes affect us and our environment? Many people wonder how many active volcanos there are. Around 50 to 70 volcanoes erupt each year. That isn’t even including the great number

prediction. GPS is one of the tools that scientist use to predict volcanic eruptions. This allows scientist to check underground for small earthquakes. The GPS tool can also detect if the magma is overpressured. If the pressure of the magma is to high, its a signal of eruption. The GPS can also detect the movement of magma underground which can also be a signal. These are so things that the GPS can do to help predict volcanic eruptions. Gas
