EAST COAST, WEST COAST PHENOMENON

GOING AROUND MANY GREEK ISLANDS WITH MY BOAT, IT WAS NOTICEABLE A DIFERENCE IN THE FORMATION OF THE COASTS AT A RATE OF 99%, THAT EAST COAST WAS SMOOTH AND THAT THE WEST COAST WAS ALMOST VERY ABRUPT.

THIS PHENOMENON WAS NOTICED IN LAND, DEPENDING WETHER I WAS ON AN EAST COAST OR ON A WEST. THIS WAS OBSERVED IN EAST AND WEST COAST OF USA, AUSTRALIA, CANADA, WEST TO EAST COAST OF ENGLAND EXCEPT DOVER COAST, DALMATIAN WEST SEA SIDE  IN EUROPE AND ALMOST EVERY WHERE ELSE.

I NEVER CAME TO A REFERENCE OF THIS REAL PHENOMENON, OR READ IT IN A BOOK, NOR I WAS TAUGHT  IT IN  SCHOOL OR TAUGHT IT IN THE UNIVERSITY. WHY?

CAN YOU GIVE A SCIENTIFIC EXPLANATION ? I CAN NOT.
