Study Notes

Geomorphology Overview

The study of geomorphology focuses on landforms, their origin, evolution, and spatial distribution.
The term 'geomorphology' is derived from three Greek words: 'geo' (earth), 'morphe' (form), and 'logos' (study).
Originally, 'geomorphology' described the study of landform shapes and their processes.

Landform Characteristics

Landforms can vary greatly in size, from small features like hills and valleys to large structures like mountains and plateaus.
Core focus includes understanding how and why landforms change over time.

Morphological Facets

Three facets of morphology in geomorphology:
- Form: the physical shape and structure of landforms.
- Process: the mechanisms by which landforms are created and altered.
- Time: the temporal changes that occur within the landscape.

Geological Forces and Processes

Geological forces driving geomorphic processes include tectonic activity, erosion, sedimentation, and weathering.
The five geomorphic processes include:
- Erosion
- Transport
- Deposition
- Weathering
- Mass movement

Steno's Landscape History

Steno's six-stage landscape history of the Tuscan region includes a sequence of development reflecting processes from youth to maturity in landscapes:
- 1. Creation of a surface
- 1. Erosion and sedimentation
- 1. Formation of valleys and hills
- 1. Development of plains
- 1. Alteration due to human activity
- 1. Rejuvenation

Study Approaches and Models

Geomorphologists employ four approaches to study landforms:
- Process-based approach
- Morphological approach
- Historical approach
- Regional approach
Process-response models are significant in geomorphology as they help predict how landforms respond to environmental changes.

Threshold Concepts and Dynamic Variables

Threshold concepts in geomorphology indicate critical points where a small change can lead to significant transformations in landforms, emphasizing their importance for understanding landscape evolution.
Dynamic variables associated with geomorphic processes include climate, geology, vegetation, and human impacts.

Terms and Concepts

Geomorphological 'isms' refer to schools of thought or perspectives within geomorphology, such as uniformitarianism, which posits that geological processes occurring in the present also occurred in the past at similar rates.
Fundamental concepts in geomorphology involve understanding processes, landforms, and timeframes, contributing to our ability to analyze and predict landscape changes.
