Usually winds blow upslope by day and downslope by night. There is a pronounced morphology characterized by a channel upslope and snout-like toes downslope. Submarine landslides are turbidity currents and consist of water-saturated sediments flowing downslope. The populations of the Central Asian mountains mostly migrate downslope rather than southwards. Winds that flow over mountains down into lower elevations are known as downslope winds. Streams carried rock debris downslope to be deposited in nearby lowlands. In hillslope sediment transport, a variety of processes move regolith downslope. Overland flow can erode soil particles and transport them downslope. "Galileo" observed evidence of recent downslope regolith movement. Wind speeds during downslope wind effect can exceed . Steam emission was at moderate level, creeping downslope toward the southwest. The Lahaina winds are also downslope winds, but are somewhat different. There are indications of material movement along the downslope direction. Other ground effects included downslope movement, slumps, and ground cracks. Terrestrial bioturbation is important in soil production, burial, organic matter content, and downslope transport.
