Volcanic landforms volcanic landforms are controlled by the geological processes that form them and act on them after they have formed thus, a given volcanic landform will be characteristic of the types of material it is made of, which in turn depends on the prior eruptive behavior of the volcano. A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice and ash unlike shield volcanoes , stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions , although some have. A volcano is an opening in earth's crust where magma breaks through, raining down molten rock, ash and gases there are several types of volcanoes a volcano is an opening in earth's crust where.

The destructive power of volcanoes volcanic eruptions in iceland have wreaked havoc on air travel due to high concentrations of ash in the atmosphere, and throughout human history eruptions have.
Volcanoes do more than pollute the air in fact, volcanic activity may actually benefit the environment in some cases while carbon dioxide gases from volcanoes join other carbon emissions in the atmosphere and contribute to global warming, the sulfur dioxide released by volcanoes can actually reverse this effect. Some volcanoes have rugged peaks formed by lava domes rather than a summit crater while others have landscape features such as massive plateaus destructive eruptions and proximity to populated areas volcanoes' capricious power could only be explained as acts of the gods,. Volcanoes are constructive forces in that they create new land, fertilize existing lands and bring many new minerals to the surface of the planet volcanoes also bring heat to the areas surrounding them and attract wildlife on land and beneath the sea volcanoes create new land when molten rock, or.
