The ocean bottom—a region nearly 2.5 times greater than the total land
area of the earth—is a vast frontier that even today is largely unexplored
and uncharted. Until about a century ago, the deep-ocean floor was completely
accessible, hidden (1)
______ beneath waters averaging over 3,600 meters deep. Totally
without light and subjected intense pressures hundreds of times greater
(2) ______ than at the Earth’s surface, the
deep-ocean bottom is a hostile environment to humans, in some ways as
forbidding and remote as the void of out space.
(3) ______ Therefore
researchers bare been taking samples of
(4) ______ deep-ocean rocks and
sediments for over a century, the first detailed global investigation of the
ocean bottom did actually (5) ______ start until
1968, with the beginning of the National Science Foundation’s Deep Sea
Drilling Project (DSDP). Used techniques first developed for the offshore oil
and (6) ______ gas industry,
the DSDP’s drill ship, the Glomar Challenger, was able to maintain a steady
position on the ocean’s surface and drill very deep waters, extracting
samples of sediments (7) ______ and
rock from the ocean floor. The Glomar Challenger’s core samples have allowed
geologists to reconstruct that the planet looked like hundreds
(8) ______ of millions
of years ago and to calculate what it will probably look like millions of
years in the future. Today largely on the strength of evidence gathered
during the Glomar Challenger’s voyages, nearly all earth scientists agree
with (9) ______ the theories of plate
construction and continental drift that explain many of the’ geological
processes that shape on the (10)
______ Earth
