Coastal Plains of India

  • To the east and west of the peninsular plateau, two narrow strips of plain lands are found , which are respectively called Eastern Coastal Plain and Western Coastal Plain.
  • Eastern Coastal and Western Coastal Plain are formed by the erosional and depositional & activities of the Sea waves and from the sediments brought by the peninsular rivers.

Indian Coastal plains

Western Coastal plain
  • Westeren coastal plain is 10 to 15 km wide and is narrower than eastern coastal plain.
  • Western coast is divided into 4 parts:
    1. Kathiawar coast (Gujarat coast)
    2. Konkan coast (Maharstra coast)
    3. Canara coast(Karnataka coast)
    4. Malabar coast (Kerala coast)
  • The Gujarat coastal plains are built up by alluvium brought by Sabarmati, Mahi, Narmada and Tapti rivers, all of which form large estuaries.
  • Malabar coast contains lakes, lagoons and backwaters locally called Kayals.
  • Vembaned Lake (Kerala) is largest of such back water lakes.

Eastern Coastal plain
  • Eastern coastal plain is 50 to 60 km wide and is broader than western coastal plain
  • The eastern coast is mainly emergent type i.e. its outline is regular and is characterized by offshore bars, sea beaches, sand ridges and lagoons.
  • Tamil Nadu coast is called Coromandel coast while Odisha and West Bengal coast is called Northern Circar coast.
  • Most of the east flowing rivers follow zig-zag path and are more border as compared to west flowing rivers. So, these east flowing rivers from delta where as west flowing rivers (like Narmada and Tapti) from estuary.
  • For example: Sunderbans delta of Ganga-Bhramaputra in West Bengal, Mahanadi delta, Godavari delta etc.
  • Region of Mahanadi delta is called Utkal Plain.

How to identify Calculator is Programmable or Non-Programmable Calculator ?

Some competitive examinations allow the use of a calculator but may permit to use of only a calculator of the non-programmable type. Calculators that are NOT programmable: This is what a non-programmable calculator looks like. List of non-programmable calculators of some famous brands like  Casio , Sharp , Texas Instruments , Hawlett Packard . Calculators that are programmable: Programmable calculators can automatically carry out a sequence of operations under the control of a stored program, much like a computer. Examples of the programmable calculator are at the top picture. These calculators runs on a Computer Algebra System (CAS). A CAS helps to make certain difficult algebraic functions automatic and less tedious. As you can see, these calculators also have graphing capabilities. A calculator with graphing capabilities is most likely to be programmable. The easy way to tell if the calculator has graphing capabilities is by looking at the larger screen than would

Flood and Drought Affected Areas in India

In India, the regional and seasonal distribution of rainfall is uneven. On the one hand, Jaislamer receives less than 9 cm of annual rainfall and on the other hand, Mawsynram, near Cherapunji, receives more than 1140 cm of annual rainfall. Similarly, most of the rainfall in India is received in the months of June, July, August and September. Generally, variations in the amount of rainfall are found more in the regions where the rainfall is uneven and less and these regions are more affected by droughts. Droughts Drought is an abnormally long dry season, which creates a clear imbalance in the availability of water. both, the vagaries of monsoon and dominant factor, which cause drought and drought like conditions. The irrigation commission, on the basis of the amount of rainfall and its variability, has divided the drought affected areas into two types: Drought Areas: Drought areas have annual rainfall less than 50 cm and variability is more than 25%. Under these areas are in

The Advent of European Companies in India

The Portugese soon established political power along the west coast of India. he was succeeded by Captain General Alfonso de Albuquerque who conquered Goa in 1510.
