← GeographyWhich outcome commonly occurs when low-silica lava cools rapidly?
A)Development of pahoehoe lava texture✓
B)Formation of columnar jointing structures
C)Explosive eruption due to vesiculation
D)Creation of steep-sided stratovolcano cones
💡 Explanation
Pahoehoe forms from fluid lava because rapid surface cooling creates a skin that wrinkles as molten lava flows underneath, therefore a smooth, ropy texture results, rather than blocky or explosive forms due to volatile content.
