Macro erosional landforms | Parabolic Valleys | Hanging Valleys | Fjords | Aretes What are macroscale erosional landforms? Macroscale erosional landforms are larger than 1 km in dimension and often contain smaller landforms (micro- and mesoscale) 1. Macroscale erosional landforms, such as Parabolic Valleys, Arêtes and Pyramidal Peaks (see Figure 1) are without a doubt …
This article was written by Dr Hannah Bickerdike. The Loch Lomond Stadial in Britain Between 12,900 and 11,700 years ago, gradual warming of Britain’s climate was interrupted by a sudden period of renewed cooling. During this period, known as the Loch Lomond or Younger Dryas Stadial, glaciers regrew in many areas of upland Britain. Evidence …
The Loch Lomond Stadial in Britain Between around 13 and 11 thousand years ago, the climate in Britain, as well as across much of Northern Europe, cooled abruptly1. This short-lived cold period temporarily reversed the general pattern of warming that drove the retreat of ice sheets after the Last Glacial Maximum, causing glaciers to readvance …
Glacial cirques, known locally as corries or coires (Scotland) and cwms (Wales), are large-scale erosional features common to many mountainous regions1,2. Classic cirques take the form of armchair-shaped hollows (see image below), with a steep headwall (which often culminates in a sharp ridge, or arête) and a gently-sloping or overdeepened valley floor (see diagram below). …
