Flowering big bluestem, a characteristic tallgrass prairie plant. The tallgrass prairie is an ecosystem native to central North America.Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination.
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the landforms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief , but also natural ...
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic data.
The topography, or relief, is characterized by the inclination , elevation, and orientation of the terrain . Topography determines the rate of precipitation or runoff and the rate of formation or erosion of the surface soil profile. The topographical setting may either hasten or retard the work of climatic forces. [60]
2) that many geomorphic systems are best understood in terms of the stochasticity of the processes occurring in them, that is, the probability distributions of event magnitudes and return times. [ 42 ] [ 43 ] This in turn has indicated the importance of chaotic determinism to landscapes, and that landscape properties are best considered ...
This category refers to topography, a general term in geography. Although it can be used to describe the study of place or large-scale phenomena, it is more widely used to describe the general study and graphic representation of landforms , the three-dimensional aspect of the Earth 's (or other planets ') surface.
Grasslands occur where there is insufficient rain to support trees, thus only grasses and a few shrubs can survive. There are three kinds of grasslands on the great plains, short grass prairie, mixed grass, and long grass prairie. In each of these, grass species serve all the keystone roles.
Farmers have practiced soil conservation for millennia. In Europe, policies such as the Common Agricultural Policy are targeting the application of best management practices such as reduced tillage, winter cover crops, [1] plant residues and grass margins in order to better address soil conservation.
