Volcano ProjectCarson ShoopRyan EckelmanThis section of our volcano project packet will be about Shield volcanoes. One shield volcano on Earth is Mauna Loa a hawaiian volcano.
They are formed when lava flows with a low velocity, that makes them broad. Lava comes out of the central summit or group of vents. With the low velocity and how fluid it flows, gives the volcano the dome or shield shape. The shield volcano is mostly formed of fluid magma that has hardened.
Other shield volcanoes other than Mauna Loa are Mauna Kea and Kohala.This next section will be Stratovolcanoes. Also known as composite cone. According to Oregon State University the composite cone is usually 50% lava. The other half is pyroclastic material. When a volcano erupts the lava and gases pass through the magma chamber.
They are carried by the dike.The dike is commonly found going straight through the volcano. They can also bend, flanking the central summit. A famous volcano that just happens to be a stratovolcano is Mt. St. Helens.
Cinder cone volcanoes are, volcanoes that are built up by cinder and ash. They also sometimes look like they have a huge bowl. There is a cinder cone volcano that is the remains of another volcano. It’s called wizard island. The wizard volcano isn’t out in the sea, but in the mainland. It is in a caldera. A caldera is a crater made by a volcano. Cinder cone volcanoes are function like normal ones, they have a central vent.
The central vent is usually surrounded by rock fragments. Did you know that cinder cone’s are sometimes referred to as scoria cone. The summary is that there are three main volcanoes. There is cinder or scoria cone, strato or composite cone, and shield cone. Shield cone volcanoes are very broad and can cover long distances. The stratovolcano is tall and steep, “I have found that they are commonly used as models more than the others”. The cinder cone volcano can kinda look like it has a bowl at times and it can cover a decent amount of land, but it covers less land than the shield volcano.
