← GeographyWhich outcome occurs when lava cools as pahoehoe?
A)Formation of smooth, ropy rock✓
B)Creation of jagged, blocky surfaces
C)Development of explosive lava fountains
D)Vigorous venting of trapped gases
💡 Explanation
The formation rocks depends upon the mechanism of cooling rate, rather than magma source, and surface texture of lava is formed. Pahoehoe forms smooth surfaces because rapid surface cooling prevents crystal growth, therefore forming ropy textures rather than other, rough, lava rock forms.
