    2. Volcanoes are formed along two types of plate boundary: destructive and constructive.   Volcanoes occur where molten rock (magma) comes to the surface of the earth. The magma rises to the surface through cracks in the crust called vents.

    3. Cone Volcanoes   When lava is thick and acidic it doesn’t flow far before cooling and solidifying, this causes cone volcanoes (aka acid cone volcanoes) to have steep sides.     Example: Mount Pelee on Martinique (an island in the Caribbean)
