For the following questions, refer to the following passage and illustration. A team of scientists is studying the composition of the sea floor near the underwater mid- Atlantic ridge volcanoes. They noticed that the ocean floor had regular alternating magnetic bands on either side of the ridge. Their observations are shown in the diagram. This effect is related to regular polarity reversals in the north and south magnetic poles of Earth.

With the understanding that solid land masses float on the liquid mantle, the scientists have concluded that the addition of new ocean floor at the mid-Atlantic ridge is the result of
a
seafloor spreading.
b
subduction.
c
earthquakes.
d
mountains.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .

there was a variety of food available on island x, but there were only large seeds and nuts on island y.

the peaceful equids (horses, donkeys and zebras) were enslaved by the human race to do our bidding -- sorry, domesticated -- several thousand years ago, and since that time they've been an invaluable resource for transportation, agriculture, warfare, companionship and sometimes-horrifying entertainment.
