What Comes out of a Volcano, Volcanic Landforms, Hot SpotsHeat from Earth’s core can escape to the outside through a gap between tectonic plates, or heat can “punch” through the middle of a tectonicplate, releasing pressure and heat to the outside.Volcanoes are areas in the earth's crust which emit lava, ash and volcanic gases.Lava vs. MagmaLava: outside Earth's crust Magma: inside Earth's crustMagma erupts as either lava or pyroclastic material.Lava- liquid magma that flows from a volcano. Its viscosity may vary.Viscosity - means "resistance to flow".Pyroclastic Material- forms when magma is blasted into the air and cools and hardens.Pyroclastic Flow - a huge, glowing cloud of hot ash and dust can race downhill at 200 mph, and can be hotter than 700 degrees Celcius. ash cloud crater strata layers main vent lava flow side vent magma chamber How are magma and lava different? magma is outside on the earth's crust and lava is inside or under the earth's crust lava is outside on the earth's crust and magma is inside or under the earth's crust mgama and lava are the same thing magma comes out of a volcano but lava stays inside What does viscosity mean? resistance speed blast explosive Where on earth does a volcano form? Volcanoes are formed where weather patterns on earth are constantly changing. Volcanies are formed where humans are digging into earth's crust. Volcanoes are formed at tectonic plate boundaries or punch through a tectonic plate to release heat. Volcanoes are formed where rivers flow in between mountain valleys.
