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 ...
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...

Remember, magma is hot, molten rock that's underground and it's called lava when it reaches the surface—uh, so the lava builds up and hardens, and a volcano forms. Now, the lava on Venus is thin. [01:54.00It spreads out easily. So shield volcanoes have very gentle, sloping sides....
Step 5 – Draw the Ground Underneath the Volcano Draw a slightly curved horizontal line right underneath the volcano. This creates the ground where the volcano is standing on. Step 6 – Draw the Ash Cloud Coming Out of the Crater Draw a continuous scalloped line until it forms a cloud of ...
The Galeras volcano is a stratovolcano. How was it formed? How are volcanoes connected to the water cycle? Describe the main characteristics of cirrus, cumulus and stratus clouds. How are coastal deserts formed? What color are cumulus clouds?
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. ...
In the hundreds of thousands of years we've been walking the planet, our numbers have grown. How is it that only about 200,000 years ago a single woman became the great-grandmother of us all? Shouldn't human history go further back than that? All About Eve A volcano in Sumatra like...
of a volcano you made for the science fair. That's the satisfaction that comes with the foaming chemical reaction produced when you mix dish soap,hydrogen peroxideand dry yeast ― and the good news is, you can make it in your home. You know, if nobody minds you making a gigantic mess...
