Pubity on Instagram: "😭 Volcanoes erupt because molten rock called magma builds up beneath Earth’s surface and becomes trapped by surrounding rock, causing pressure to rise. As heat and gases expand, the pressure eventually becomes too strong, forcing magma upward through cracks or vents in the crust. When it reaches the surface, the magma erupts as lava, ash, and gas, releasing the built-up pressure and reshaping the land around it. (RealtorMerna via ViralHog) #surprise"
