What Is A Volcano Internet Geography A volcano is a conical hill or mountain formed by material from the mantle being forced through an opening or vent in the earth’s crust. volcanoes have vents or openings that provide direct access to lava and gases stored below the earth’s surface and can release these elements into the atmosphere. there are several different types of. The main types and features of volcanoes. a volcano is a landform, usually the size of a mountain, that is typically conical and has a cater and vent through which lava, hot gases, steam and rock fragments are or have been erupted through the crust of the earth. at constructive (divergent) plate margins, when two tectonic plates move apart.
What Are The Main Features Of A Volcano Internet Geography A volcano is a rupture in the crust of a planetary mass object, such as earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. the process that forms volcanoes is called volcanism. on earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of earth. A volcano is an opening in a planet or moon’s crust through which molten rock, hot gases, and other materials erupt. volcanoes often form a hill or mountain as layers of rock and ash build up from repeated eruptions. volcanoes are classified as active, dormant, or extinct. active volcanoes have a recent history of eruptions; they are likely. A pyroclastic flow is a superheated mixture of hot steam, ash, rock and dust. a pyroclastic flow can travel down the side of a volcano at very high speeds with temperatures over 400 degrees celsius. composite volcanoes can rise over 8000 feet. a simple cross section of a composite volcano. when composite volcanoes erupt they are explosive and. Volcano, vent in the crust of earth or another planet or satellite, from which issue eruptions of molten rock, hot rock fragments, and hot gases. a volcanic eruption is an awesome display of earth’s power. yet, while eruptions are spectacular to watch, they can cause disastrous loss of life and property, especially in densely populated.

A volcano is an opening in the earth’s crust through which lava, volcanic ash, and gases escape. volcanic eruptions are partly driven by pressure from dissolved gas, much as escaping gases force the cork out of a bottle of champagne. beneath a volcano, liquid magma containing dissolved gases rises through cracks in the earth’s crust. Volcanoes can look like small mountains or hills. a volcano is an opening in the earth's crust that allows magma, hot ash and gases to escape. composite volcanoes are the most common type of.
