swimming machines (og practice set 6)
tunas, mackerels, and billfishes (marlins, sailfishes, and swordfish) swim continuously. feeding,courtship,
reproduction, and even rest are carried out while in constant motion. as a result, practically every aspect of the body form
and function of these swimming machines is adapted to enhance their ability to swim.
many of the adaptations of these fishes serve to reduce water resistance (drag). interestingly enough,several of these hydrodynamic adaptations resemble features designed to improve the aerodynamics of high-speed aircraft. though human engineers are new to the game, tunas and their relatives evolved theirhigh-tech designs long ago.
tunas, mackerels, and billfishes have made streamlining into an art form. their bodies are sleek and compact. the body shapes of tunas, in fact, are nearly ideal from an engineering point of view. most species lack scales over most of the body, making it smooth and slippery. the eyes lie flush with the body and do not protrude at all. they are also covered with a slick, transparent lid that reduces drag. the fins
are stiff, smooth, and narrow, qualities that also help cut drag. when not in use, the fins are tucked into
special grooves or depressions so that they lie flush with the body and do not break up its smooth
contours. airplanes retract their landing gear while in flight
for the same reason.
tunas, mackerels, and billfishes have even more sophisticated adaptations than these to improve their
hydrodynamics. the long bill of marlins, sailfishes, and swordfish probably helps them slip through the
water. many supersonic aircraft have a similar needle at the nose.
most tunas and billfishes have a series of keels and finlets near the tail. although most of their scales
have been lost, tunas and mackerels retain a patch of coarse scales near the head called the corselet.
the keels, finlets, and corselet help direct the flow of water over the body surface in such as way as to
reduce resistance (see the figure). again, supersonic jets
have similar features.

question 1-9
investigation of the deep-ocean
keywords: ocean, researchers, techniques, samples, rocks
the ocean bottom – a region nearly 2.5 times greater than the total land area of the earth –
that even today is largely unexplored and uncharted. until about a century ago, the deep – ocean floor was
subjected to intense pressures hundreds of times greater than at the earths surface, the deep – ocean bottom
although researchers have taken samples of deep – ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the national science foundations deep sea drilling project (dsdp). using techniques first developed for the offshore oil and gas industry, the dsdps drill ship, the glomar challenger, was able to maintain a steady the ocean floor.
the glomar challenger completed 96 voyages in a 15 – year research program that ended in november 1983. during this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world. the glomar challengers core
samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future. today, largely on the
of evidence gathered during the glomar challengers voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the earth.
the cores of sediment drilled by the glomar challenger have also yielded information critical to understanding the worlds past climates. deep – ocean sediments provide a climatic record stretching back
chemical and biological activity that rapidly destroy much land – based evidence of past climates. this record has already provided insights into the patterns and causes of past climatic change – information that may be used to predict future climates.

(d) techniques used by scientists to explore outer space were similar to those used in ocean exploration
4. which of the following is true of the glomar challenger?

(c) it has gone on over 100 voyages.
(d) it made its first dsdp voyage in 1968.
(a) breaking
(b) locating

(b) two geological theories became more widely accepted by scientists.
(c) information was revealed about the earths past climatic changes.

although the growth in canadas population has slowed down by 1966 (the increase in the first half of the 1960s was only nine percent). another large population wave was coming over the horizon.
