Mount. Saint Helens is changing earth’s surface through other phenomenons such as earthquakes, tectonic plates and pressure, Volcanic Eruption. According to “Mount St. Helens Volcanic Eruption” “Hot magma gathered deep underneath the mountain, building up pressure as it was pushed by tectonic plates”. This shows that when a volcano erupts like Mount St. Helens tectonic plates have a big role involved with the eruption because there is pressure being built up inside creating a massive eruption. This can be a slow process because it can take years to build up and erupt also the eruption took lasted for nine hours. . This evidence is from Mount St. Helens Volcanic Eruption readings. “Earthquakes are unpredictable event in which masses of rock shift below Earth's surface, releasing enormous amounts of energy and sending out shockwaves that sometimes cause the ground to shake dramatically”. …show more content…
Also this evidence came from Mount St. Helens Volcanic Eruption readings”. This shows that earthquakes play a huge role in the eruptions. Yes, this phenomena changes the earth’s surface by destroying land and making it look different. This came from on of the photo called Spirit Lake After Eruption. Vast plates of Earth's crust that float on a layer of liquid magma, causing earthquakes and volcanic or other geological activities where the plates meet and slide against each other. This shows that the tectonic plates play a big role in the eruption. “The process during which a volcano releases pressurized magma, ash, and hardened rock from beneath Earth's surface to above ground. A mountain that acts as a vent for pressurized steam, ash, and magma, which gather beneath the surface of
