Which increased hazard accompanies building roads atop discontinuous permafrost regions?

💡 Explanation

Thermokarst formation is accelerated by road construction insulating the permafrost, causing thawing and subsidence; because subsidence undermines the roadbed, therefore roads become unstable rather than benefiting from increased albedo preventing melting.

• Which consequence results when increased polar ice melting?
• Which consequence results when soil aridity increases with unrestricted grazing?
• Which process controls uplift when two continental plates collide at reverse fault zones?
• Which mechanism causes localized surface uplift preceding volcanic eruption?
• Which consequence results when Earth's decreased rotation rate weakens the Coriolis effect?
• Which increasing risk results when intense rainfall interacts with existing karst topography?
