3rd grade volcano report
posted January 11, 2007 - 5:43pm Volcanoes can be very terrifying and scary. This report is about real live very terrifying and scary volcanoes. There are three different types of volcanoes that have many different characteristic properties. The three different types of volcanoes are Shield, Composite or Strato, and Cinder Cone. They all have real
common characteristics and they are crater, vents, side vents, magma, lava, magma chamber, conduit, ash, and they have black, brownish, and gray tones on them.
The Shield volcano is different than the other two volcanoes. The volcano is flat, and the lava is much hotter not like the two other volcanoes. It's more of an island shape so it forms Hawaiian Islands. Mauna Loa is one example.
The Composite or Strato volcano is made out of a lot of alternating layers of lava and ash. All of them are in the Cascade Range. They are also in Japan. Mount Saint Helen’s, Mount Rainier, Mount Shasta, Mount Hood, Mount Adams, and Mount Fuji are some examples.
The Cinder Cone volcano has a cone shape on the top. This type is made out of different layers of broken rocks and ash. Wizard Island in Crater Lake and Lava Butte in Oregon are couple examples.
The Lava Dome is not a mountain. The whole thing is made of a thick mass of lava. Lava just spills out and makes a dome. It squeezes out like toothpaste. Lassen Peak in California is an example.
Volcanoes can be found everywhere in the world. There are 17 major volcanoes and they are Mount Pelee, El Chichan, Lassen Peak, Mauna Loa, Mount Saint Helen’s, Paricutin, and Sutsey are in America and the West Indies. In Asia there are Krakatau, Mount Tambora, and Mount Pinatubo. The ones in Europe are Vesuvius, Stromboli, Thira, and Mount Etna.
Volcanoes are found in the Pacific Ring of Fire. The Pacific Ring of Fire is around the Pacific Ocean. They’re 141 volcanoes in the Pacific Ring of Fire.
Volcanoes at the Cascade Range and in Japan are Composite or Strato. Oregon volcanoes are Cinder Cones. Shield Volcanoes are in Hawaii. Lava Domes are in California.
Volcanoes can form in many different ways. One of the ways it forms is when magma finds cracks in the Earth's crust. The magma trying to escape, the pressure creates it. When the pressure is too intense, the crust breaks to start a volcanic form. Magma creates a mountain formation. The crater forms its shape at the top of the volcano.
The Cinder Cone volcano becomes larger with the layers of broken rocks and ash. The Composite or Strato volcano is formed by many eruptions creating alternating layers of lava and ash. The Shield volcano forms by runny hot lava so it makes it large.
These three volcanoes have things in common. Two plates crashing form them all. Lava spills through the crust's surface. They all form with layers of lava and ash, a crater at the top of the mountain, Igneous rock and erupt.
Some more information of how a volcano can form is by earthquakes, by paretic eruptions, or by magnetic eruptions. Volcanoes can form in many ways.
Volcanoes can be very terrifying and scary. When Mount Saint Helen’s erupted it killed approximately 57 people and even people from Montana could hear it! One old Vesuvius erupted in 79 A.D., a lot of people was killed. They did not even know that there would be a volcano. Since 1400 A.D., 2000,000 people had been killed from volcanoes.
Volcanoes are slow. First, magma blasts off, then the magma travels through the conduit, the eruption! It can produce islands, mudslides, and igneous rocks. Only Shield volcanoes can produce islands. Volcanoes can produce Pumice, an igneous rock that floats.
This is a very good report containing non-fiction geology terms of science. I think volcanoes are so terrifying and scary and I want to see a real sample of not exactly melted lava.
