             PALEO-LIFE                      OF                     ORGANISMS                         Cardium       LCardium was one of the pre-existing multicellular marine organisms. It formed in late- creteceous period.                  Shape          : oval                  Symmetry  : Equivalve and Equilateral         Dentition    : Heterodont           Hingement : No distinct hinge plate         Ribs              : Radiating Ribs

   Polarizing   microscope   We are using microscope for our studies in       schools and colleges . Microscope is used to analyse the minute organisms and blood for detail study . But in geology field we use only petrology Polarizing microscope. It is helpful in study the shape and structure of the mineral or a rock by the 0.3mm thin section of the the specimens(rocks or minerals).       

                        CRATERS FALL              We saw numerous stars and planets by our raw eyes and also by the  telescope. We saw moon every day . It looks beautiful but it have numerous craters. Craters sizes differ from 1mm to 1km .
