What is the kinds of volcanoes according to their activity?
Volcanologists have classified volcanoes into groups based on the shape of the volcano, the materials they are built of, and the way the volcano erupts. The groups are: 1. Composite volcanoes, also called strato volcanoes, are formed by alternating layers of lava and rock fragments. This is the reason they are called composite. 2. Shield volcanoes also called shields are huge in size. They are built by many layers of runny lava flows. Lava spills out of a central vent or group of vents. A broad shaped, gently sloping cone is formed. This is caused by the very fluid, basaltic lava which can’t be piled up into steep mounds. 3. A cinder cone is a steep conical hill formed above a vent. Cinder cones are among the most common volcanic landforms found in the world. They aren’t famous as their eruptions usually don’t cause any loss of life. Cinder cones are chiefly formed by Strombolian eruptions. The cones usually grow up in groups and they often occur on the flanks of strato volcanoes and s
