When you sit down and really give it a good think, though, people do seem to use the words “lava” and “magma” pretty interchangeably. So what’s the difference between lava and magma? How Do Volcanoes Erupt Anyway? You might have thought volcanoes were the coolest thing as a ki...
How are volcanoes harmful? How is water pollution affecting the hydrologic cycle? How does the rock cycle affect the Earth? How does wind affect the water cycle? Why do volcanoes erupt? How does the water cycle affect hurricanes? How does drought affect the water cycle?
Many shield volcanoes erupt with great frequency (every few years or so). Eruption Frequency The caldera at Kaguyak Volcano, in Alaska, is about 1.5 miles (2.5 km) in diameter. Photo courtesy USGS Volcanic activity can also produce other interesting structures, such as calderas and lava ...

How do volcanoes affect the lithosphere, hydrosphere, and biosphere? Lithosphere, Hydrosphere, and Biosphere: Volcanic eruptions are rarely just localized phenomena, the power of the eruption and the volume of ejected matter can impact the entire world. The areas of impact are the lithosphere, hy...
However, volcanoes sometimes erupt in the middle of tectonic plates. The sources of these hotspots might be mantle plumes, mushroom-shaped pillars of hot rock ascending from the deep mantle to sear overlying material like a blowtorch. As tectonic plates wander over such plumes, geologists think ...
“When we do it with hurricanes, we'll see landfall maps where there's a cone of probability of where the hurricane could fall,” Gregg says. “That cone of probability is made up of hundreds of models that are being propagated forward in time.” Instead of looking at the humidity, win...
