Is magma and lava the same
Witryna21 maj 2016 · When magma reaches the surface and erupts from a volcano, it officially becomes lava. There are actually different kinds of lava depending on its thickness or viscosity. WitrynaMagma rises and overflows when a volcano erupts or when a deep break in the Earth occurs. Lava is the fluid that oozes out of a volcano or fracture, usually mixed with steam and gas. Fresh lava has a temperature range of 1,300° to 2,200° F (700° to 1,200° C) and glows red hot to white hot as it flows.
