Question

discuss four importants of geomorphology to humanity​

Answer 1

Answer:

Geomorphology, as a critical component of physical geography, is needed to understand natural landform changes and potential hazards for populations.

Answer 2

Answer:

Geomorphology, as a critical component of physical geography, is needed to understand natural landform changes and potential hazards for populations.

Through varying height and degree of ground-surface inclination, landforms interact with climate and directly influence hydrologic and soil-forming processes. Landform is the best correlation of vegetation and soil patterns at meso- and microscales.

Role of landform

Macroclimate accounts for the largest share of systematic environmental variation at the

macroscale or ecoregional level. At the mesoscale, landform (geology and topography)

breaks up the broad patterns. For example, solar energy will be received and processed

differently by a field of sand dunes, a lacrustrine plain, or an upland hummocky moraine.

Within the same macroclimate, broad-scale landforms break up the east-west

climatic pattern that would occur otherwise and provide a basis for further differentiation

of mesoscale ecosystems, known as landscape mosaics. The character of a landscape

mosaic with identical geology will vary by the climate zone. For example, vertical

limestone would form quite different landscapes in a subarctic climate than in hot and

arid climates. Limestone in a subarctic climate occurs in depressions and shows intense

karstification, whereas in hot and arid climates, it occurs in marked relief with a few cave

tunnels and canyons inherited from colder Pleistocene time.

Landforms (with their geologic substrate, surface shape, and relief) influence

place-to-place variations in ecological factors, such as water availability and exposure to

radiant solar energy. Through varying height and degree of ground-surface inclination,

landforms interact with climate and directly influence hydrologic and soil-forming

processes.

Landform is the best correlation of vegetation and soil patterns at meso- and

microscales. This is because landform controls the intensity of key factors important to

plants and to the soils that develop with them (Hack and Goodlet 1960; Swanson and

others 1988). The importance of landform is apparent in a number of approaches to

classification of forestland (for example, Barnes and others 1982). Even in areas of  

relatively little topographic relief, such as the glacial landforms of the upper Midwest of

the United States, landform explains a great deal of the variability of ecosystems across

the landscape (Host et al. 1987).
