Volcanoes obtain their energies from such movement and pressure. Volcanoes form at the boundaries of these plate where two types of movement occurs, two plates will collide with each other or the plates will move apart from each other. Some of these plates layers are cooled and are made up of rigid rocks. The affects on the landscape is lava that releases onto the Earth's surface. When that lava comes to the Earths surface, it is red hot and sometimes the temperature is more than 2012 degrees Fahrenheit.
After significant time, the hard lava forms a volcanic mountain. Volcanoes can form in many different sizes and shapes. They can look like a cone, have steep looking flanks, or look as if they were long cracks in the earth’s crust. (Plummer et al., 2000). If the mountain is very tall, then there is a greater chance that it was formed from past eruptions.
Volcanoes are magnificent and powerful land features. The magma erupts from the Earth forming islands, cooling to form rocks, and changing the landscape on eruption at a time. They can erupt at any time! Since volcanoes are dangerous we have developed technology to detect these impressive explosions. Since Hawaii was formed by a volcano when you visit Hawaii you are standing on cooled lava!

Volcanoes This paper will define and discuss the volcano to include: types of volcanoes, formation of a volcano, and elements of a volcano; such as, lava, rock fragments, and gas. This paper also tells a little bit about volcanic activity in different parts of the world. What is a volcano? A volcano is a vent in the earth from which molten rock and gas erupt. The molten rock that erupts from the volcano forms a hill or mountain around the vent.

Crater Lake is constructed of different types of volcanic rock, has been a part of different eruptions and has had much activity since it was once Mount Mazma. Due to the volcanic threats that are still provided from the lake and its surrounding cinder cones, hazard mitigation, monitoring and monitoring is vital to nearby locations. All of these important topics will be discussed further in the continuing paragraphs. Geological History: Before Crater Lake was indeed Crater Lake, it was once a 12,000 foot high stratovolcano known as Mount Mazma. Mt.
Due to this, the study of volcanoes and the service that volcanologists provide to the public by way of information and predictions on activity is immeasurable. Named for the Roman god Vulcan, volcanoes have both intrigued and frightened mankind for centuries. Human like footprints dating back 300,000 years have been found in the solidified lava of Roccamonfina volcano in Italy (Onion, 2013). These footprints, called the "Devil's Trail" appear to indicate that these ancestors were escaping an eruption. In Turkey, a 9,000 year old painting depicting a volcanic eruption was discovered in 1964 during an excavation of Catalhyuk (Oskin, B., 2012).
It lies on the Juan de Fuca Plate. This is a divergent boundary. It was formed by the subduction of the Juan de Fuca Plate and the North American Plate. This volcano also has lahars which are large mudflows that happen in the deposits of sediments that surrounds volcanoes; they can be hot or cold. This volcano includes but not limited to the rock andesite.
