ACTIVIDAD DE VOLCANES

We shave ideas about the volcanes eruptions we studied the topic in 6° grade, they built the definition:

Volcanic eruptions can spew large amounts of matter (gas and particles) into the atmosphere affecting penetration of sunlight even at great distances. The particulate matter has even stalled jet engines almost causing fatal crashes. Many but not all volcanic activity is related to tectonic plate movements (circle of fire) while others  involve hot spots in the earth's crust. Many volcanoes are dormant. Study  volcanic activity may help predict if and when they may return to life and to know how they erupt.
