Helens in Washington state is known for its massive volcanic eruption that occurred in The eruption reduced the elevation of the mountain from 9, feet to 8, feet and left a mile wide horseshoe-shaped crater where the mountain stood. Volcanoes are big holes that let out hot gasses , ash and magma from deep inside the Earth.
Many volcanoes are mountains , made up of layers of lava and ash. Many volcanoes have several vents — a main one, and secondary ones that branch off the main vent. The Earth has three layers — the crust at the very top, then the mantle , then the core at the very middle of the planet. The largest active volcano in the world is Mauna Loa, on the Hawaiian islands.
When a volcano erupts, magma comes up and out through the vents. Depending on how thick the magma is, volcanoes can be different shapes such as shield , composite or dome. Ash from volcanoes is very good for growing things. It adds nutrients to the soil. The Earth has three layers: About 50 volcanoes erupt every year! The largest active volcano is Mauna Loa. Most volcanoes can be found in countries that have coastlines on the Pacific Ocean — this is called the Ring of Fire.
Gas, ash and magma can come out of volcanoes. Test your knowledge of this chapter with a 30 question practice chapter exam. Other Practice Exams in this course.

A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet. In simple terms a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth.
What is a volcano? A volcano is a very deep hole in the Earth’s top layer that can let out hot gasses, ash and lava. Many volcanoes are also mountains. Volcanoes have long shafts that go all the way down .
The Volcanoes chapter of this High School Physical Science Homework Help course helps students complete their volcanoes homework and earn better grades. This homework help resource uses simple and fun videos that are about five minutes long. Shield Volcano: A shield volcano is the largest volcano on the earth that erupt fluid lava. It usually erupts the basaltic type of lava that has low viscosity, which means that it can flow very far and quickly. The largest shield volcano on the earth is Mauna Loa that is situated on the big island of Hawaii.
