Answer:
Shield
Shape
-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... Some of the largest volcanoes in the world are shield volcanoes.
Consistency of magma
-This viscous liquid can range from the consistency of syrup to extremely stiff, with little or no flow apparent. This is regulated by the amount of silica in the lava, with higher levels of the mineral resulting in a higher viscosity.
Volcanic material
-Shield volcanoes are composed almost entirely of relatively thin lava flows built up over a central vent. Most shields were formed by low viscosity basaltic magma that flows easily down slope away form the summit vent.
Cinder
Shape
-Cinder cones are the most common type of volcano. A cinder cone has a cone shape, but is much smaller than a composite volcano. Cinder cones rarely reach 300 meters in height but they have steep sides. Cinder cones grow rapidly, usually from a single eruption cycle.
Consistency of magma
-Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium).
Volcanic material
-Cinder cones are small volume cones consisting predominantly of tephra that result from strombolian eruptions. They usually consist of basaltic to andesitic material. They are actually fall deposits that are built surrounding the eruptive vent.
Composite
Shape
-Composite cones are tall, cone shaped volcanoes that produce explosive eruptions. Shield volcanoes form very large, gently sloped volcanoes with a wide base. Cinder cones are the smallest volcanic landform.
Consistencyof magma
-The volcanoes form steep cones, rather than rounded shapes, because the magma is viscous. Composite volcano magma is felsic, which means it contains silicate-rich minerals rhyolite, andesite, and dacite.
Volcanic material
-Many of Earth's most beautiful mountains are stratovolcanoes—also referred to as composite volcanoes...Stratovolcanoes show interlayering of lava flows and typically up to 50 percent pyroclastic material, which is why they are sometimes called composite volcanoes.
