NS
RIVERS OF NORTH INDIA THAT FLOWS FROM HIMALAYAS BRING A VARIETY OF
MATERIALS INCLUDING SILT, CLAY, SAND AND GRAVEL. THEY DEPOSIT
MATERIALS CALLED ALLUVIAL SOIL, IN THE PLAINS OF NORTH INDIA. THIS SOIL
IS VERY FERTILE AND SUPPORTS NEARLY HALF THE POPULATION OF INDIA.
*FARMERS GROW NATURAL INDICATOR PLANTS, LIKE HYDRANGEA, TO CHECK
THE NATURE OF SOIL. IF THESOIL IS ACIDIC THE PLANT PRODUCES PINK
FLOWERS, AND IF BASIC THE SAME PLANT PRODUCES BLUE FLOWERS.

ADDITIONAL INFORMATION
LIGHT CONTD:8
*DIAMONDS & WATER SHINE DUE TO REFLECTION OF LIGHT
*SHADOWS ARE ALWAYS FORMED AT THE BACK OF THE OBJECT
*NO TWO DESIGNS FORMED IN A KALEIDOSCOPE ARE ALIKE
*IRRESPECTIVE OF THE COLOUR OF LIGHT EMITTED, THE COLOUR OF THE SHADOW WILL ALWAYS BE
DARK/BLACK
*AN OBJECT CAN FORM TWO OR MORE SHADOWS IF THE LIGHT COMES FROM DIFFERENT SOURCES AT
THE SAME TIME, LIKE IN A CRICKET MATCH WHEN THE SPOT LIGHTS ARE FROM DIFFERENT ANGLES
