Der Stuersche Bach durchschneidet in seinem Gesamtverlauf vom
Kogeler See über die Vordermühle bis zur Mündung in den Plauer See
einen Endmoränenzug. In den Steilwänden befinden sich die
Nisthöhlen der Eisvögel.
The end moraine near Bad Stuer Vordermuehle has been cut into two
by the river "Stuerscher Bach". Thus it has created a valley and a
high cliff in which kingfishers have settled down. Lots of nests
can be seen in the cliff.
Moränen (v. frz.: moraine „Geröll“) sind die Gesamtheit
des vom Gletscher transportierten Materials, im speziellen die
Schuttablagerungen, die von Gletschern bei ihrer Bewegung mitbewegt
oder aufgehäuft werden, sowie die im Gelände erkennbaren
Formationen.
Endmoränen bilden sich als Schuttanhäufung am Gletscherende, wenn
sich die Gletscherstirn für längere Zeit nicht bewegt. An ihnen
kann man besonders gut die größte Ausdehnung des Gletschers
erkennen.
Aufgaben: macht ein Foto von euch/dem GPS vor der Steilwand und
sendet es mit den Antworten der folgenden Fragen an uns.
1. Aus welchem Material besteht die Steilwand?
2. Welche anderen Vögel nisten in ihr? (mindestens zwei
Arten)
Bitte uns die Antworten mailen! Viel Erfolg!
Moraine refers to any glacially formed accumulation of
unconsolidated debris which can occur in currently glaciated and
formerly glaciated regions, such as those areas acted upon by a
past ice age. This debris may have been plucked off the valley
floor as a glacier advanced or fallen off the valley walls as a
result of frost wedging. Moraines may be composed of silt like
glacial flour to large boulders. The debris is typically angular.
Moraines may be on the glacier’s surface or deposited as
piles or sheets of debris where the glacier has melted. Moraines
may also occur when glacier or iceberg transported rocks fall into
the sea as the ice melts. End moraines or terminal moraines are
ridges of unconsolidated debris deposited at the snout or end of
the glacier. They usually reflect the shape of the glacier's
terminus. Glaciers act much like a conveyor belt carrying debris
from the top of the glacier to the bottom where it deposits it in
end moraines.
End moraine size and shape is determined by whether the glacier is
advancing, receding or at equilibrium. The longer the terminus of
the glacier stays in one place the more accumulation there will be.
There are two types of end moraines, terminal and recession
moraines. Terminal moraines mark the maximum advance of the
glacier. Recessional moraines are small ridges left as a glacier
pauses during its retreat. After a glacier retreats the end moraine
may be destroyed by postglacial erosion.
Tasks: Please take a photo of the cliff and a GPS device. Send an
email and answer the following questions as well:
1. What is the material that the steep wall consists of?
2. Which other birds live in the cliff? (name two, please)
Please email us the answers! Good luck!
