- (I) A volcanic island is born only after a long
and violent struggle between the forces of the
earth and the sea. (II) Such a brief intrusion of
earth in the vast, overwhelming expanse of sea
has always fascinated the human mind. (III) It
begins to form when hot lava breaks through a
cracked and uneven part of the sea-bed where
the earth's crust is weak. (IV) Unlike the land
volcano, it has to build upwards despite the
immense water-pressure until it finally reaches
the surface. (V) Even then it is too soft to
withstand the waves and remains underwater
until the cone is pushed into the air from below
and the lava hardens.
