Which outcome occurs when shield volcano lava's viscosity increases?

💡 Explanation

Steeper cones occur; **viscosity increases resistance to flow**, therefore lava piles up rather than spreading because frictional forces overcome gravitational forces, unlike low-viscosity lava which produces extensive lava plains.
