The way volcanoes erupt

The way volcanoes erupt it usually takes a long time and this is how volcanoes erupt. First a volcano makes something called magma from melted rock. The magma goes through a circulation. It has to form at the bottom of the volcano and then start its way up the main vent. The main vent is a hole that is in the volcano and when the volcano is ready to erupt, the lava is at the top of the main vent. The magma goes up the main vent slowly while it gets hotter and hotter. When the magma is about half way up the main vent it turns into lava. Lava is a very hot liquid which burns the remaining rocks from the magma. The lava slowly continues up the main vent. While going up the lava continues to get hotter and hotter. The ash and rocks are collected and the lava is getting hotter and hotter while the lava is continuing its way up the main vent. When the lava is at the top of the main vent the volcano erupts. The lava blasts out of the volcano along with ash, rocks, and a cloud of dust that is very thick. The ash and rock crumble to the ground, but the lava is either moving down the volcano side very slowly or at a high speed. The lava burns down almost everything in its way, and it sometimes leaves bits of things burning. The lava from the volcano can cool fast, or sometimesthe lava will slowly cool down from its intense heat. Lava that cools slowly forms igneous rocks. There are many types of igneous rocks. Volcanoes can damage themselves in the explosion. A volcano literally blows its top off. One of the volcanoes that have blown its top from an explosion is Mt. St. Helens. Mt. St. Helens has erupted more than once.
Volcanoes can be under water or on land. Volcanoes that are under water take a longer time than if they are on land because they are the under water. The water slows down the magma and lava but if the volcano is on land the lava and magma can move quicker up the main vent. It just depends on the environment how fast the volcano can make the magma the magma makes lava and the volcano makes an explosion. If the volcano is under water the cooled lava will probably make an island. The Hawaiian Islands is an example of island made by a chain of volcanoes. Have you ever wanted to learn what happens inside of a volcano? You might already know that lava comes out of a volcano. But did you know how it is formed? It is formed inside of a volcano in the magma chamber. Rocks and otherbits of thing are melted in the magma chamber. Melted rock is called magma. When magma is still in the magma chamber it can make cracks in the earth and you can actually see the hot magma but do not go near it. Magma that reaches the earth's surface is called lava. Another thing that forms inside smoke but first the magma first has to make its way up the main vent. When the magma gets about half way the magma is hot enough it becomes lava a very hot liquid that burns down the rocks and stuff that the magma doesn't melt. The lava continues its way up the main vent getting hotter and hotter as it goes higher and higher up the main vent. When the lava is at the top of the main vent, when the volcano is about to make an explosion. When the volcano makes the explosion ash and rocks blast out of the volcano top along with the lava and a dark dust cloud. The lava makes its way down the side of the volcano either going fast or slow. The lava burns down trees and other stuff including animals but some of the animals can survive the very hot very dangerous lava. Volcanoes are very dangerous. Well now you know what happens inside of volcanoes! Now go to the front page and go to a different page on our web site and be prepared to learn more about volcanoes.

A volcano can cause manyhorrible things like earthquakes. They can cause mud slides. Mud slides are very powerful. They can destroy cities. In Pompeii when a volcano erupted the whole city was covered in lava. During the eruption some people evacuated. A volcano can cause many avalanches. While magma is still in the earth's crust it causes cracks on the earth's surface showing the magma. Mud slides are so powerful they can push boulders over. Avalanches are sometimes made from when a volcano erupts. Volcanoes can be very dangerous in many ways. Some things volcanoes do are good. The Hawaiian Islands were formed by volcanoes. If the volcano is an underwater volcano they erupt and form islands. When the lava cools it forms into a rock called igneous rock. Sometimes in the igneous rock you can find crystals of many shapes and colors. Igneous rock is formed from melted rock that has cooled and hardened. Some of the rocks are called Gabbros, Granite, Rhyolite, Basalt, Pumice, and Obsidian. In footprints during a mudslide seeds can be protected. After the mudslide they can sprout out of the footprint. Very small animals like ants, termites, or ground squirrels can survive from avalanches because they can burrow underground and are protected. Birds are smart enough to fly away when they hear or see the mud slides, lava, or avalanches.

The Pacific Ring of Fire is an area of frequent earthquakes and volcanic eruptions encircling the basin of the Pacific Ocean. The Ring of Fire has 452 volcanoes and is home to over 50% of the world's active and dormant volcanoes. Ninety percent of the world's earthquakes and 81% of the world's largest earthquakes occur along the Ring of Fire.

The world's largest, active volcano is Mauna Loa in Hawaii, where famous coffee is grown in the rich volcanic soils. Mauna Loa is 13,677 feet above sea level. From its base below sea level to its summit, Mauna Loa is taller than Mount Everest.
