Moränens

Moränens is a term used in glaciology to denote moraine deposits, and in some contexts it appears in Swedish-language sources as a label for morainic landscapes or as the name of a geographic area characterized by such deposits. A moraine is an accumulation of unconsolidated glacial till deposited at the margins or at the terminus of a glacier.

There are several moraine types. Terminal moraines mark the furthest advance of a glacier, while recessional moraines form as the glacier pauses during retreat. Lateral moraines run along the sides of a glacier, and medial moraines develop where two glaciers coalesce. Ground moraines blanket large areas of bedrock once covered by ice. Moraines are typically composed of unsorted mixtures of clay, silt, sand, gravel, and boulders, with rough, angular fragments.

MORÄNen formation involves the transport of bedrock and surface debris by ice, followed by deposition when the ice loses capacity to carry particles. Post-glacial processes, including meltwater action and soil development, further modify moraine landscapes. Moraines provide records of past ice extents and climatic fluctuations and are used to reconstruct glacial histories.

In terms of landscape impact, moraines influence drainage patterns, soil fertility, and topography, and they can host wetlands, forests, or agricultural land depending on drainage, texture, and moisture. Regions such as Scandinavia and many parts of North America contain extensive moraine belts, reflecting multiple glaciation events. See also glacial till, moraine, glaciation, and drumlin fields.
