Down
- 1. type of volcano with alternating layers of lava flows and pyroclastic material, steep sides, most explosive eruptions, but can be quiet- MOST DANGEROUS
- 2. type of volcano with very steep slopes, smallest, form from small explosive eruptions, made of pyroclastic material.
- 3. when one tectonic plate slides underneath another at a convergent boundary
- 4. A volcanically active area at Earth's surface, far from the edges of tectonic plate boundaries.
- 5. thickest layer of the earth's interior; contains liquid rock
- 7. type of volcano with broad/wide base, gently sloped sides, generally "quiet eruptions."
