SHAPING THE LANDSCAPE :-
The basic material of the earth surface is solid rock , valleys ,deserts , soil and sand are all evidence of the powerful agends of weathering ,erosion and deposition which constantly shape and transform the earth's landscape . Water , either flowing continually in river or seas or frozen and compacted into solid sheets of ice , has the most clearly visible impact on the earth's surface . But wind can transport fragments of rock over huge distance and strip away protective layer of vegetation , exposing rock surface to the impact of extreme heat and cold .
