Which landform develops extensively because seasonal thawing destabilizes slopes?

💡 Explanation

Thermokarst forms because the active layer melts, causing subsidence. Solifluction, a primary mechanism, occurs therefore affecting landscapes rather than glacial features. These effects dominate rather than esker/drumlin/kame actions at those latitudes because seasonal melt is the driver.
