introduction to Physical geography and its scope

in this slide u can study about physical geography and its scope

1. INTRODUCTION TO PHYSICAL GEOGRAPHY

2. definitions Physical geography is considered the accumulation of different branches of earth science. For example Climatology, Oceanography, Botany, etc. Thus, it includes consideration of surface relief of the globe. Different geographers have defined it in different ways. According to Tarr and Von Engeleh , ‘Physical geography is the study of physical features of the earth and their influence on men.’ In the words of Lobeck , ‘The study of the physical environment along contributes physiographic.’ According to Strahler , ‘Physical geography is the study of unification of a number of earth sciences.’ Physical geography also studies the spatial pattern and spatial relationship of environmental components of the globe in the original context. It also studies the causes of original patterns of such spatial relationships.

3. SCOPE The scope of physical geography includes the study of earth relief features and physical features, such as plains, mountains, hills, etc. Geomorphology is an important branch of geography. It is defined as the science of landforms with an emphasis on their origin, evolution, form and distribution across the physical landscape. It is concerned with the scientific study of the origin and evolution of relief features of the earth’s surface and their relation to its geological structures. It has two sub fields Fluvial geomorphology Dessert geomorphology These fields deal with the study of some specific landforms which consists of various environments. One of the common things between these fields is the fact that these are all united by the core processes which shaped them, which were mainly tectonic or climatic processes.

4. Pedology is the study of soil, including types, formation, and regional distribution over earth. Climatology deals with the study of the atmospheric conditions and related climatic and weather phenomena. Relates to study of how climate can be affected by human and nature influence. The aim of this field of study is to determine how the earth’s climate has changed thru the ages and to predict future trends in climate change. Includes the systematic and regional studies of atmospheric composition. I.e, weather, and climate. It is sub-divided largely into the climates of various regions and the study of the specific phenomena or time periods. E.g tropical cyclone rainfall climatology and paleoclimatology. Oceanography includes the description and analysis of a physical and biological aspect of the hydrosphere. The study of marine resources and their biological characteristics is included under oceanography which is an important branch of physical geography The main aim of oceanography is to study the various oceanic process for a better understanding of their effects on life on earth. Weather refers to the atmospheric conditions in terms of temperature, pressure, humidity, and precipitation, etc. of a particular place at any given time. the climate is related to the weather conditions of any region in the long-term perspective.

5. Meteorology is a field that deals with the forecasting of day-to-day weather conditions. Contrary to climatology, which aims to forecast long-term climatic conditions, meteorology pertains to short-term forecasting. It deals with the prediction of weather conditions in the immediate future, on the basis of the different atmospheric factors such as temperature, moisture, air pressure, etc. Biogeography concerned with the biological phenomena in space, especially in terms of the distribution of various kinds of floral and faunal species. also, it is defined as the study of the distribution of plants and animals and their relationship with the environment. The field can largely be divided into five sub-fields: island biogeography, paleobiogeography, phylogeography, zoogeography(the study of animal’s distribution and their relationship with their relationship) and phytogeography(the study of plants distribution)
