Short essay on different types of volcanoes.
What are the three main volcanoes? There are three main types of volcano - composite or strato, shield and dome. Composite Volcanoes. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and flows. The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.
Types of volcanoes. The lava and pyroclastic material (clouds of ash, lava fragments and vapor) that comes out from volcanoes can make many different kinds of land shapes. There are two basic kinds of volcanoes. Shield volcanoes. These volcanoes are formed by fluid low-silica mafic lava.Shield volcanoes are built out of layers of lava from continual eruptions (without explosions).

Summary: A summary of the three different types of volcanoes -- the composite volcano, the shield volcano, and the cinder cone volcano. All volcanoes have different shapes, sizes, and types of eruptions. When magma beneath the Earth's surface is forced up through any opening in Earth's crust, it is.
Plate boundaries. There are a number of different types of plate boundary. Destructive plate boundary. A destructive plate boundary is sometimes called a convergent or tensional plate margin. This.
Composite Volcano. Composite volcanoes are steep-sided volcanoes composed of many layers of volcanic rocks, usually made from high-viscosity lava, ash and rock debris. These types of volcanoes are tall conical mountains composed of lava flows and other ejecta in alternate layers, the strata that give rise to the name.
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle. Therefore, on Earth, volcanoes are generally found where tectonic plates are.
