Explanation:

• First question: Pahoehoe lava is basaltic, has a smooth and ropy texture. Scoria is a volcanic rock, aa lava is rough, pegmatite is a type of igneous rock (not lava flow).
• Second question: Shield volcanoes are large, gently - sloping, and composed mainly of basaltic lava. Composite volcanoes have explosive eruptions with ash and lava layers. Cinder cones are small. "Flat" is not a standard volcano type in this context.
