Physical Description on Landforms

Physical Description on Landforms  Physical Description on LandformsPhysical descriptions can take many forms ranging from physical description of human appearance to describing the earth and its phenomena. However in this script, I describe the different landforms.

A landform in the globe sciences and geology sub-fields, entails a geomorphologic unit, and is widely defined by its surface form and position in the landscape. Therefore it can be defined as part of the topography, and as such, is typically an element of terrain.

Landform elements also comprise seascape and oceanic water body border features including seas, peninsulas, and bays, sub-aqueous terrain features such as submersed mountain ranges, the great ocean basins and volcanoes.

Physical Description on Physical Characteristics

Landforms are grouped by characteristic physical attributes such as soil type, elevation, rock exposure, slope, stratification and orientation.

Gross physical description of landforms constitute  intuitive elements such as hills, berms, mounds, ridges, cliffs, valleys, rivers, peninsulas and many other size-scaled and structural fundamentals as well as various types of inland and oceanic sub surface features and water bodies.

This view in Great misty Mountains National Park has the easily identifiable physical features of a undulating plain, distant foothills, actually part of a broad valley, a backdrop of the old, much worn Appalachian heap range.

Hierarchy of classes as Part of physical Description

The highest-order landforms are exemplified by the continents and oceans. Landform constitutes high-order landforms that can be further recognized and systematically given a solid definition such as hill-tops, fore slopes, shoulders, saddles, and back slopes.

a number of generic landform elements consisting of; pits, ridges, peaks, plains, channels, passes, and pools, may be got from a digital elevation sample using some robotic techniques where the data has been collected by current satellites and stereoscopic airborne surveillance cameras.

Elementary landforms such as relief units, facets and segments are the least homogeneous segments of the land surface, at the certain scale/resolution. These are places with relatively homogenous morph metric characteristics, restricted by lines of discontinuity.

A flat terrain or a hill can be viewed at various scales ranging from same few hundred meters to hundreds and thousands of kilometers. Therefore, the spatial allocation of landforms is often scale-dependent as is the instance for soils and geological strata.

Several factors, including plate tectonics, erosion and deposition, can produce and have an effect on landforms. Biological factors also have influence landforms; for instance, note the function of vegetation in the expansion of dune systems and salt marshes, and the effort of corals and algae in the creation of coral reefs.

Physical Description on the Difference between Relief and Topography

Relief can be defined as the vertical dimension of land surface. Topography on the other hand can be described as the study of terrain. All the same the word is often used as a synonym for relief itself. Anytime relief is described underwater, then the term bathymetry is used.

In cartography, many varying techniques are used to explain relief in physical description; this includes Triangulated irregular network and contour lines.
