A volcano is a fissure – opening or vent – in the earth’s crust through which molten rocks and gases erupt. The molten rocks can be in the form of mixture of hot gases, ash, lava, or other extremely hot substances within the earth’s crust. A volcano looks like a huge heap of ...
Which ocean has a ring of volcanoes around it? Which Galilean satellite has active volcanoes? What countries have the most volcanoes? What type of volcano is Surtsey? What kind of volcanoes created the island of Rapa Nui? What type of volcano is Katmai?
Volcano pipes carry carbon-cased rocks from deep within the Earth called kimberlite. A main vent of a volcano can result in a main volcanic pipe and secondary pipes as well. These pipes create small, secondary cones like bumps on a larger volcanic mountain. Once these pipes have been inactive...
Mountains, plains, plateaus, soils, rocks, etc. as we see them today, are believed to have gone through many phases, with about 80% of it being carved by the action of volcanoes. A volcano is simply a rapture (opening or vent) on the earth’s surface (crust) through which molten mag...
What is a vent in a volcano? Does temperature inversion happen in the exosphere? What does oscillation mean in meteorology? What is a pyroclastic flow surge? How cold is the troposphere? What weather is associated with cA air masses?
The main features of a volcano include a vent, a summit crater and a magma chamber.The vent is an opening through which volcanic material is erupted. Volcanoes can have more than one vent. The summit crater is the large concave opening that holds the central vent at the top of the volcan...
"I heard explosions, I heard hissing, I heard this remarkable chugging sound, like a train. Through all that time I was thinking that I could use these sounds to find out what is happening inside the volcano."Daniel PendickNew Scientist...
Cinder cone volcano eruptions are like a hybrid between a shield and composite eruption, though the characteristics are more similar to the shield volcano. Like a shield volcano, cinder cone volcanoes feature basaltic lava. However, their lava is slightly thicker. This allows for the trapping of ...
Volcano Basics: A volcano is a vent or opening in the Earth’s crust through which molten rock, ash, and gases can erupt. The material that comes out during an eruption builds up to form a mountain-like structure. 2.Types of Volcanoes: ...
In Europe, Mt. Etna in Sicily is quite active, as isVesuvius(the volcano that buried Pompeii and Herculaneum in 79 AD). These mountains continue to affect surrounding regions with earthquakes and occasional flows. Not every volcano builds up a mountain. Some vent volcanoes send pillows of lava...
