Which type of volcanic eruption is characterized by highly viscous lava, explosive gas ejections, and the formation of steep-sided composite cones?
A. Hawaiian
B. Strombolian
C. Plinian✓ Correct Answer
D. Icelandic
💡 Solution & Explanation
Plinian eruptions represent extremely violent volcanic events characterized by highly viscous, gas-rich magma that generates towering columns of fragmental ash and pumice. These eruptions contrast sharply with effusive Hawaiian eruptions, which feature fluid basaltic lava flows and minimal explosive activity. Volcanology classifications are essential components of physical geography preparation for competitive assessments.
