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 subs
If the magma pressure rises to a high enough level, or a crack opens up in the crust, the molten rock will spew out at the earth's surface. If this happens, the flowing magma (now called lava) forms a volcano. The structure of the volcano, and the intensity of the volcanic eruption...

Much like any other kind of natural disaster, there is something awe-inspiring about a volcano eruption. If you can see them at a safe distance then you can admire the ferocious beauty of the phenomenon. Bright red lava will pour out with a huge plume of smoke emitting from the volcano a...
Today it is a volcano that is 1,391 feet in height and surrounded by about 90 square miles of lava flows. Photo by Brian Overcast / Alamy Stock Photo. ADVERTISEMENT What Are Cinder Cones? Cinder cones, also known as pyroclastic cones, are the smallest and the simplest type of volcano. ...
What type of volcano forms from tephra eruptions? What do super volcanoes look like? What are the characteristics of a shield volcano? What type of rock are volcanoes made of? How did volcanoes affect the origins of the seas? How are metamorphic rocks formed? What happens when a shield volc...
In our study we used the element sulfur of which there are four stable forms (calledisotopes). Each has a slightly different mass. This is important because natural processes can selectively separate lighter isotopes from heavier isotopes. Much like snacking on a bag of M&M's where you prefer...

Nardia succulenta, a pioneer liverwort occurring on foot slopes of the 1968 cone of the volcano Arenal (Costa Rica), forms layered deposits with volcanic ash up to 15 cm thick. These adhere to vertical cliffs and bridge volcanic boulders to form a continuous carpet, thus creating a habitat ...
It might not be something you can control—a freak weather event, a supply issue, or even a volcano—but your customers will have the same high expectations of you and will be disappointed. Here’s a template to help you set things right: Dear [Customer Name/Valued Customers, etc.], ...
