Answer:
Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to moulding the nature of the continent over millions of years.
They all contain a gravitational pull that allows them to stay together and to keep objects within orbit
The answer is friction. As ocean wave approach the shoreline, they are affected by the sea bed through process such as refraction, shoaling, bottom friction and wave-breaking. However wave breaking also occurs in deep water when the waves re too steep. If the waves meet major structurer or abrupt changes in the coastline, they will be transformed by diffraction.
