Impact of Sea Level Changes

Impact of Sea Level Rise:
  1. Due to the rise of sea water, the various rivers are flooded.
  2. As a result of rise in sea level, almost 33 % of the world’s crop lands could be submerged.
  3. As a result of rise in sea level, the mouths of drainage basins will undergo submergence.
  4. As a result of rise in sea level, beaches, coastal dune & bars will be destroys.
  5. Due to sea level rise, the ecosystem of deltas will be damages.

Impact of Sea Level Fall:

  1. A fall in sea level may cause changes in the base levels of rivers.
  2. As a result of fall in sea level, deposited of substances produced by various corrosive processes.
  3. Sea level falling greatly regulates the spread of coral reefs.
  4. Water fall is one of the reasons for river’s regeneration.
  5. Deposition & erosion rates increased in the deep sea environments.

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.    ...

Sources of Water Mass

Sub-surface water masses formation is more active in the North & South Atlantic & the South Pacific & moderately active in the North Pacific. The sub-surface water masses is not active in the Indian Ocean because of its location in the southern hemisphere. The following arte major source areas of the origin of subsurface water masses-                                            i.           Norwegian Sea Area,                                           ii.           Irminger ...

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...
