Volcanism is the process by which molten rock material is moved from one part of the earth's crust to another, or from within the earth's crust to the surface. This molten material is called *magma* while it is still beneath the surface, but it is called *lava* as soon as it reaches the surface. All this molten rock material eventually cools and solidifies into igneous rock.
Lava
lava rock
When Volcanoes erupt the surface is melted by the lava
Shield volcanoes form extensive fluid lava flow that erupts numerous times.
Because the lava from volcanoes form igneous rocks
No, volcanoes do not need lava to be volcanoes.
NO, volcanoes make lava.
Lava cools down and accumulates into rock as it reaches Earth's surface
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
Shield volcanoes generally form from quiet eruptions. Layers of hot, mafic lava flow out around the vent and slowly build up to form the cone.from lava that pours down from lava that pours down
yes. They are made form harden lava
From lava that came from volcanoes. They harden to form igneous rocks.
