4. What kind of volcanoes have the appearance e we usually assoclate with volcanoes? 5. What is the simplest type of volcano and how is It formed?

4. The type of volcanoes that have the appearance we usually associate with volcanoes are called Composite or Stratovolcanoes. These volcanoes have a conical shape with steep sides and are characterized by a mixture of explosive eruptions and lava flows. They are built up over time through repeated eruptions, with each eruption adding a new layer of material to the volcano's structure.<br /><br />5. The simplest type of volcano is called a Cinder Cone volcano. It is formed when a single eruption occurs, ejecting small fragments of lava called cinders that fall around the vent, building up a circular or oval-shaped hill. Cinder Cone volcanoes are typically small, with a diameter of less than 1 kilometer, and have steep slopes. They are usually short-lived, with a lifespan of only a few years, and are often found on the flanks Composite or Shield volcanoes.
