World Landforms, a Leading Educational Portal, Provides Information About Different Types of Volcanoes


Maple Grove, MN -- (SBWIRE) -- 04/21/2015 -- The evolution of the Earth and its geographical features is a fascinating topic. At World landforms, a leading educational portal, they provide information about different types of volcanoes which are quite informative for students and other people interested in this area. As planet earth evolved, a number of landforms came into existence, some of them being rivers, mountains, valleys, lakes, cliffs, deserts and volcano. Out of these various geographical features, volcanoes are the most interesting ones. They are molten lava that erupts by rupturing the crust allowing various gases, hot magma and volcanic ashes to escape from within.

Different kinds of volcanoes can be found on various continents such as shield volcanoes, spatter cones, composite volcanoes, complex volcanoes and cinder cones. Shield volcanoes are made entirely of molten lava. These are large in structure and are in the shape of a circular fan, giving it a shield look. Composite volcanoes, which are also known as strato-volcanoes, are layered in structure. These are conical in shape due to the repetitive flow of lava over many years.

Talking about the geographical features and their formation, one of the representatives of World landforms stated, "There are many landforms on the earth's surface. They are actually on other planets, as well. One thing is certain, there are major landforms that cover the world that we live on. Generally, when the tectonic plates converge or diverge, volcanic eruptions take place. There are a few other types of volcanoes such as super volcanoes, cryptodomes, lava domes and submarine volcanoes. The volcanic emission injects sulphur dioxide, carbon dioxide, water vapor and sulfuric acid into the atmosphere which contributes to acid rain. This is a major effect of a volcanic eruption."
