There are several different types of volcanoes: steep stratovolcanoes, wide shield volcanoes, and mounded lava domes. The shape of a volcano actually depends on the types of lava that itâs made up of.And so, there are several different types of lava.'a lava. The type of lava coming out of a volcano depends on its mineral content. Some lava is very thin, and can flow out of a volcano in great rivers that go for dozens of kilometers. Other lava is very thick, and only flows for a short distance before cooling and hardening.
Report Abuse. Igneous rocks are crystalline solids which form directly from the cooling of magma.The chemistry of the parent rock largely determines the composition of the resulting metamorphic rock. So the major difference is that Igneous rocks are made from magna and metamorphic rock is made from any other rock.hen magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground. Metamorphic rocks are rocks that have morphed into another kind of rock.
Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals.
