Answer to Question 1

Answer: Phaneritic and pegmatitic

Answer to Question 2

Answer: Felsic magmas are very viscous, which makes them more likely to remain below the surface and cool intrusively than to make it to the surface. (Students may also make the argument that rhyolite is not as resistant as granite and therefore more prone to erosion.)
