Stratified drift typically forms in areas where glacial meltwater streams transport and sort sediments as they flow away from a melting glacier. The layering in stratified drift can indicate changes in energy levels within the water flow, revealing past environmental conditions during glaciation.
In geology, drift is a name for all sediment (clay, silt, sand, gravel, boulders) transported by a glacier and deposited directly by or from the ice, or by glacial meltwater.
26 Δεκ 2021 · Glacial drift is usually subdivided into two major categories: till, on the one hand, and material variously called stratified drift, washed drift, or sorted drift, on the other hand (Figure 7-46). (A really good term for this second kind of drift has not yet been invented.)
24 Μαΐ 2024 · Stratified drift refers to sediment deposits arranged in distinct layers, typically left behind by glaciers or meltwater streams. These layers can vary in composition, size, and sorting based...

29 Μαρ 2022 · The term stratified drift refers to glacial drift that has been reworked by glacial meltwater and then deposited either in direct contact with glacier ice or at some point more or less far away from the glacier, in a wide variety of depositional environments.
What is a Stratification? Forests throughout the world show STRATIFICATION: a pattern of vertical layering in a forest community. New Zealand’s podocarp-broadleaf forests have 5 distinct vertical layers: EMERGENT, CANOPY, SUBCANOPY, SHRUB, and GROUND. For each STRATA, you MUST be able to write about:
