Answer to Question 1

True

Answer to Question 2

Lava domes, also known as volcanic domes and plug domes, are steep-sided, bulbous mountains that form when viscous felsic magma, and occasionally intermediate magma, is forced toward the surface. Because felsic magma is so viscous, it moves upward very slowly and only when the pressure from below is great. Lava dome eruptions are some of the most violent and destructive.

Examples: Mount St. Helens and Mount Pele
