How Golda Meir, Indira Gandhi, and Margaret Thatcher Wrought a New Standard of Leadership. It is surely time to recognize what an immense improvement has been wrought in world standards of governance by the rise of female national leaders.
Shield volcanoes, the third type of volcano, are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently sloping cone of flat, domical shape, with a profile much like that of a warrior's shield.
Layers of rock and lava form composite volcanoes. Composite volcanoes release lava and rock when they erupt. Identifying a type of volcano helps predict the kind of eruption to expect from it. The lava of a spatter cone volcano has a continuous flow. Lava, ash, and gases are ejected through a volcano vent.he different types of volcanoes are: composite (or stratovolcanoes), shield, cinder cones and spatter cones. Throughout the world, one can see pictures of the four types of volcanoes, each type indicative of the active underground world we often view as static.
