First‚ we will discuss Mount St. Helens Volcano. Mount St. Helens is a stratovolcano located in the Pacific Northwest of the United States within Washington State. A stratovolcano is also known as a composite cone‚ which is “a large symmetrical structure that consists of alternating layers of explosively erupted cinders and ash interspersed with lava flows (Lutgens‚ 2012.)” Due to the cone shape of the volcano‚ stratovolcanoes are known for creating large explosive eruptions that can eject vast amounts

Do you know what the biggest active volcano in the world is? Mauna Loa is so big in volume and so heavy that it causes the Pacific Plate that it sits on to sag under its weight! Although Mauna Loa has not erupted as many times as its sister‚ Kilauea‚ it has caused more damage with every earthquake and explosion it has had. The elevation of Mauna Loa is 13‚678 ft and its height from the ocean floor is 30‚080 ft. Mauna Loa is a shield volcano‚ but it can develop into a cinder cone. It has had

This volcano is the classic model volcano for science projects. You form the cone of the volcano around a bottle and then mix non-toxic kitchen chemicals to cause the volcano to erupt. Form the Chemical Volcano The cinder cone of the volcano is formed using clay. You’ll need a lot less ’volcano’ material if you make a general volcano shape out of paper and then just cover it with clay. Erupting Volcano Ingredients 1:- warm water 2:- baking soda 3:- liquid dishwashing detergent 4:- vinegar

CINDER CONE VOLCANO The cinder cone volcano‚ commonly found in volcanic areas‚ are constructed of rocks and ashes. Gas created from the lava is blown into the air which then “cools and solidifies as small rocks or cinders”. Cinder cone eruptions “take place in basaltic volcanic fields” that immensely effect the human population surrounded by it. Cinder cone eruptions majorly impact the environment by distributing volcanic gases‚ volcanic landslides and blasting tephra. One of the long-term impacts

The movie “Volcano” was about an active volcano forming into the city of Los Angeles‚ California. The evaporating of harmful gases‚ earthquakes‚ and some evidences from the manhole are the manifestations showed that an underground volcano was forming under the city. This means that there was already lava under the city and the ground cannot take the pressure anymore so it formed a volcano. The physical changes in the movie are the breaking of glasses from buildings‚ breaking of buildings

form which then rises through cracks and erupts to form volcanoes. As volcanoes move away from a hotspot‚ they start to erode and become inactive. Maui is the third oldest volcano of the main Hawaiian islands and could still erupt one more time. Haleakalā or the East Maui Volcano is also a shield volcano or a broad‚ domed volcano with sloping sides. It forms more than 75% of the Hawaiian Island of Maui and has an alert level of “normal.” The last time Maui erupted was in the 17th century‚ but even

A Look Into Volcanoes By: BJ E-mail: Bran18@aol.com I. Introduction Volcano: defined is a mountain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth ’s surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides‚ but some can be gently sloping mountains or even flat tablelands‚ plateaus‚ or plains. The volcanoes above sea level are the best known‚ but the vast majority of the

Saint Helen’s Volcano‚ part of the cascade mount range‚ is associated with the subduction zone of the Juan du Fuca plate into the North American plate‚ as is most of the volcanism in this mount range (USGS Geology & History). The eruption intensity is normally quite explosive but Mt. Saint Hellen’s has experienced the peaceful one on occasion (USGS Geology & History). With frequent eruption every couple hundred years (rough estimate at best)‚ Mt. Saint Helen’s is the most active volcano of the Cascade

helping to improve our environment/earth. Nowadays‚ people don’t see difference between “active volcano” and “Holocene volcano” or they don’t understand it. When people say a volcano is “active”‚ they are using the term wrong. Scientist says that‚ “...it is misleading to restrict “active volcano” to recorded human memories: we prefer to add another identifying word (“historically active” or “Holocene volcano”).” (Source 1: How Many Active Volcanoes Are There?). People are probably confused on what
