Correct option is B
The correct matching of volcanic cones with their illustrations is as follows:
·
A. Cinder →
I. Mt. Izalco: Cinder cones are small, steep-sided volcanoes formed from explosive eruptions of lava fragments. Mt. Izalco in El Salvador is a well-known example.
·
B. Composite →
IV. Stromboli: Composite volcanoes (or stratovolcanoes) are large, steep-sided, and built up by multiple layers of lava, tephra, and volcanic ash. Stromboli in Italy fits this category.
·
C. Basic Lava →
II. Mauna Loa: Shield volcanoes, like Mauna Loa in Hawaii, are formed from low-viscosity basic (basaltic) lava that spreads out in wide, gentle slopes.
·
D. Acid Lava →
III. Mt. Fuzuyama: Acidic lava, being highly viscous, forms steep-sided volcanoes. Mt. Fuzuyama (Fujiyama) in Japan is an example of an acid lava volcano.
Key Points:
·
Cinder cones are characterized by steep sides and small size, often found near larger volcanoes.
·
Composite volcanoes are associated with violent eruptions and alternating layers of lava and ash.
·
Basic lava forms broad shield volcanoes due to its low viscosity and high fluidity.
·
Acid lava results in steep, dome-shaped volcanoes due to its high viscosity
