Bay,Gulf,Strait,Isthmus,Peninsula Explained !!

∎ Bay ➤ A bay is a body of water that is partly surrounded by land. Bays empty out into larger bodies of water like oceans and lakes. They are sometimes confused with other bodies of water such as gulfs, but bays are typically smaller . There are various ways in which bays can form. The largest bays have developed through plate tectonics. As the super-continent Pangaea broke up along curved and indented fault lines, the continents moved apart and left large bays; these include the Gulf of Guinea, the Gulf of Mexico, and the Bay of Bengal, which is the world's largest bay. Bays also form through coastal erosion by rivers and glaciers. A bay formed by a glacier is a fjord. Rias are created by rivers and are characterized by more gradual slopes. Bays can also be found along the shores of lakes. Bays are usually much calmer and more protected than seas or oceans . The land surrounding a bay often reduces the strength of winds and blocks waves. Most bays make excellent harbors and m...

Anabatic and Katabatic winds

                              Anabatic = moving upwards ;    Katabatic = moving downwards . Anabatic winds which  flow upslope of a mountain from lower valleys  develop during daytime in calm sunny weather. They are    warm winds which blows up a steep slope or  mountain  side, driven by heating of the slope through  insolation .   Air which is in contact with slopes that are warmed expands upward and cool and sinks over neighbouring valleys. Anabatic winds are usually slow , at only 1-2m/s and are rarely important expect near coasts where they can increase the strength of sea breezes.   Anabatic winds are particularly useful to soaring  glider  pilots who can use them to increase the aircraft's altitude. Anabatic winds can be detrimental to the maximum downhill speed of cyclists.      Katabatic winds a...

Dew Point Explained !!

                                              Why do cold drinks sweat in hot weather ? The  dew point  is the  temperature  at which  water vapour   condenses  into  liquid water  , ie. it  is the temperature at which the air can no longer "hold" all of the  water vapor  which is mixed with it, and some of the water vapor must  condense  into liquid water. The dew point is a reflection of the humidity.  The dew point of  humid  air will be higher than the dew point of dry air.  When air has reached the dew-point temperature at a particular pressure, the water vapor in the air is in equilibrium with liquid water, meaning water vapor is condensing at the same rate at which liquid water is evaporating. Below the dew point, liquid water will begin to condense on solid surface...
