Favourable Environment for Coral Reef Formation

The reefs of cemented & compacted rigid massive structures of numberless skeletons of dead coral animals are called coral reefs.
The Favorite Environment for Coral Reef Formation:

  1. Tropical Water: Coral thrive in tropical water- between 30°N & 30°S latitudes.
  2. Temperature: Coral require temperature between 23°C to 25°C for their growth.
  3. Depth: The ideal depths for coral growth are 45m to 55m below sea surface, where there is abundant sunlight available.
  4. Salinity: The range of salinity within which corals grow is 27‰.
  5. Turbidity: Turbidity inhibits the growth of corals because coral require sediment free water.
  6. Light: The most favorable zone for the development of coral is Photic Zone of upper sea level. Sunray is reached properly this zone.
  7. Clear Water: Corals need clear water that is free from abundant sediments.
  8. Adequate Food Supply: There must be adequate food supply to nourish the abundant life of the coral reef.
  9. Adequate Oxygen Supply: Corals need clear oxygen generated water with sufficient supplies of microscopic life as food.
  10. Base: Corals require firm platform to which they can cement their skeletons.

Behaviouralism in geography

Behaviouralism Behaviouralism is an approach in human geography that came to prominence in the human geography of the 1960s and 1970s. It goes out of the idea that people are the determining factor in the explanation of space. Behaviouralism tries to give an explanation of the spatiallity of human activities. And thereby they use a complex universally applicable model.  Definition of Behaviouralism: The particular aspect with which geographical content is analyzed using mathematical statistics & human sensitivity, is called behavioralism. Concept of Behaviouralism: The Behaviouralism revolution is a theoretical concept. Its theories are not based on assumptions, but are actually explored through ascending methods based on the experience of human behavior. An analysis of the significance of geographical issues in behavioral perspectives within a system, so therefore is no definite boundary to behavioral geography. The main purpose of behaviouralism geography is to in...

Concentric zone theory

Theories of City Structure-Concentric Zone Theory Introduction: The Concentric or Zonal Theory of urban landuse was first proposed in 1923 by E.W. Burgess. He was a sociologist. The idea behind the concentric model is that the development of a city takes place outwards from its central area in a series of concentric circles to form zones.  Assumption:        i.           Cultural & social heterogeneity of the population.       ii.           Commercial-industrial base to the economy of the city.     iii.           Private ownership of property & economic competition for space.     iv.           Expanding area & population of the city.       v.    ...

T-S Diagram

Definition: The diagram by which the salinity & temperature of the sea water are expressed is called T-S diagram. Prepared: T-S Diagram was prepared by Helland Harsenin (1916) with the objective to  determine the density of water at various depth. Characteristics: The Temperature ‘T’ & Salinity ‘S’ observed at the particular depth are represented by a single point in this diagram. The plotted points of T & S generally fall on a well defined curve, in which temperature & salinity decrease together. The density of water tends to increase with depth. In T-S Diagram, it may be observed that many combinations of temperature & salinity can yield the same density. In T-S Diagram, it may be observed that the density of water tends to increase with depth.  Diagrammatic Example: Significance: The T-S Diagram is a tool of great utility in Oceanography. The T-S Diagram is the way to visualize layering of water. The T-S Diagram helps in t...
