Volcanoes

A low, flat, gently sloping volcano built from many flows of fluid, low-viscosity basaltic lava

• Cinder Cone

• Composite Volcano

• Shield Volcano

• Lava Dome

A steep, cone-shaped hill or small mountain made of volcanic ash, cinders, and bombs piled up around a volcano's opening. There are dissolved gasses in magma chamber, causing an explosive eruption.

NGSS.MS-ESS2-1

A dense, destructive mass of very hot ash, lava fragments, and gases ejected explosively from a volcano and typically flowing downslope at great speed.

• cinder cone

• ash cloud

NGSS.MS-ESS3-2

A volcanic eruption with fluid, low viscosity lava. Typical of Shield Volcanoes

• Explosive eruption

• Non-violent, gentle eruption

A violent and unpredictable eruption— the result of magma that is thicker & more viscous, and higher in gas content. Produces Composite volcanoes & Lava domes

• Explosive eruption

• Non-violent, gentle eruption
