Types of Sand Dunes

In this Geoshortqa we are going to know about types of Sand Dunes. Types of Sand Dunes, Geoshortqa Sand Dunes Sand dunes are heaps of sand found in deserts . Generally , their heights vary from a few metres to 20m , but in some cases dunes are several hundred metres high and 5 to 8 km long .   The formation of sand dunes requires  • Wind of high velocity  • Abundant sand  • Obstacles such as trees , bushes , forests , rock outcrops , walls against , which dunes may settle  • Ideal places i.e. dune complex , dune colony or dune chain . Dunes formed due to obstacles like hushes , walls etc. are called nebkhas , where dune formed besides desert depressions are called lunettes.   Dunes are classified on the basis of morphology , structure , orientation , location , internal structure , ground pattern and number of slip faces . These are the various types of sand dunes  a) Transverse Dunes are dunes deposited transverse to the prevailing winds direct...

Urban System - Primate City and Rank Size Rule

In this Geoshortqa we know about Urban System  Urban System There are different urban systems that co-exist together in any urban region of the world. These systems are classified on th basis of size and spatial distribution as there is a certain degree of organisation in their size and spatial order.  These urban systems include small towns, medium sized towns and large cities. To study the order of size relationship and spatial distribution, relation between city rank and city size (in terms of population) is to be examined. The Law of Primate city and Rank size rule depict the relation between the size and spatial distribution of towns. Urban System, Geoshortqa Primate City The law of Primate city by Mark Jefferso in 1939 Main theme : The Law of Primate City is premised on the observation that the country's leading city is usually disproportionately larger than others in the system. e.g. Copenhagen is nine times the size of Aarhus etc. According to Jefferson , "Pr...

Settlement classification based on size

   In this Geoshortqa we know about the settlement classification based on size. Settlements are classified according to their size in following manner. Megalopolis   A group of conurbations consisting of more than 10 million people each. Conurbation   A group of large cities and their suburbs consisting of to 10 million people. Metropolis   A large city and its suburbs consisting of multiple cities and towns. The population is usually I to 3 million. Settlement classification based on size , Geoshortqa Large City   A city with a large population and many services. The population is less than one million people, but over 300000 people. Small City  A city would have abundant services, but not as many as a large city. The population of a city is 100000 people to 300000.  Large Town  A large town has a population of 20000 to 100000. Small Town A small town has a population of 1000 to 20000.  Village   A village generally does not hav...

Models of Urban Land Use

In this Geoshortqa we know about Models of Urban Land Use Models of Urban Land Use A number of theories have been devised to describe and explain the patterns involved in the geographical arrangement of various categories of urban land use in different cities. The three popular models, based on empirical studies in different cultural and economic settings, which explain the internal structure of cities are as follows  (i) The Concentric Zone Model by E W Burgess.  (ii) The Wedge or Sectoral Model by Homer Hoyt and M R Davis.  (iii) The Multiple Nuclei Model by C D Harris and EL Ullman. Models of Urban Land Use, Geoshortqa Concentric Zone Model The Concentric Zone Model of urban land use or 'ecological theory of city structure' was proposed by E W Burgess in 1924 and then revised in 1927.  A system of five concentric zones was identified by Burgess, each characterised by a particular type of land use.  (i) Zone I (Central Business District-CBD) : The central pla...
