It's made up of hardened lava and the remnants of previously erupted volcanic rock that's accumulated over the centuries, carving the sides of the mountain. In turn, the lava is so thick that it ends up solidifying quite quickly, although it generates gas internally that comes out in the flowing lava rivers. Some volcanoes are tall cones and others are just cracks in the ground (figure 1).As you might expect, the shape of a volcano is related to the composition of its magma. The name "volcano" has its origin from the name of Vulcan, a god of fire in Roman mythology.. As pressure in the molten rock builds up it needs to escape somewhere. The part of the conduit that ejects lava and volcanic ash. So it forces its way up “fissures” which are narrow cracks in the earths crust.Once the magma erupts through the earth’s surface it’s called lava. Lava Flow~a stream or sheet of molten or solidified lava.
