What are the four approaches used by geomorphologists in studying landforms?
- Process–response (process–form) or functional approach. 2. Landform evolution approach. 3. Approach focusing on characterizing landforms and landform systems. 4. Environmentally sensitive approach to landforms.
What is the focus of historical geomorphology?
Study of landform evolution or changes in landforms over medium and long timescales, usually well beyond the span of an individual human’s experience.
What is the focus of process geomorphology?
Study of the processes responsible for landform development and the mechanics of geomorphic processes.
What is the timescale typically associated with historical geomorphology?
Centuries, millennia, millions, and hundreds of millions of years.
What kind of science does the landform evolution approach have its roots in?
Historical geological science (geo-history).
What is the focus of the approach that stems from geographical spatial science?
Characterizing landforms and landform systems.
What does the environmentally sensitive approach to landforms focus on?
Landforms, systems of landforms, and landscapes at regional to global scales.
What does process–response approach utilize in its methodology?
Chemistry and physics, and it utilizes a systems methodology.
Who first proposed the concept of 'Base Level' for streams and rivers?
J.W. Powell
Which scientist is known for identifying ancient pluvial Lake Bonneville and discussing faulting/mountain building in Utah?
G.K. Gilbert
Who proposed the concept of the 'Davisian Cycle' which includes the stages of youth, mature, old age, peneplane, and rejuvenation?
William Morris Davis
What did T.C. Chamberlin propose as a methodology for scientific inquiry?
Multiple working hypotheses
Which scientist is known for studying and popularizing evidence for ancient glaciations of the Alps?
Louis Agassiz
What are the characteristics of a meandering stream that can be measured in quantitative geomorphology?
radius of curvature, meander wavelength
Describe the landscape characteristics during the old age stage of the Davisian cycle.
very broad and gently sloping valleys, extensive floodplains, mass-wasting dominates fluvial processes
What are the primary features of a landscape in the maturity stage of the Davisian cycle?
well-integrated drainage system, relief at a maximum, hillslopes and valley sides dominate the landscape
What is the ultimate result of erosion of land areas according to the Horton/Strahler approach?
peneplane
What shift did the Horton/Strahler approach promote in the field of geomorphology?
from landform study to quantitative process study
Explore the different approaches used by geomorphologists in studying landforms, including process-response, landform evolution, and historical geological science. Understand the methodologies and historical dimensions involved in the study of landforms.
