The Sea Around Us

Island are fragile things, destroyed at last. They are, for the most part, created by volcanoes, far out from land. It may take millions  of years to make just one island! It is one of the paradoxes in the ways of the earth that such a force, seemingly so destructive, can create. A volcanic eruption in the sea is different than a land one. It has the water pressing down and resisting it. When one occurs, ship in volcanic zones may suddenly find themselves in violently disturbed water. The sea appears to boil or bubble turbulently Floating up from the deep, hidden places of the actual eruption com the bodies of fishes and other deep-sea creatures, and quanities of ash and pumice.

Almost from the moment of its creation, a volcanic island is doomed to destruction. Another eruption may actually hasten its own destruction by exploding it. A landslide may occur. Something will happen.

It is a mystery how island are colonized by animals, but they may arrive by air. Charles Darwin raised, from a ball of mud off a bird, 82 plants! So they may arrive from the air, and the animals may come from the water, floating on log rafts.   



That's all for now!
