Go to: http://earthguide.ucsd.edu/eoc/teachers/t_tectonics/p_seafloorspreading.html. Read and
complete the following statements based on the “Key Points”
9. Seafloor spreading takes place at _______________________and produces basalt, the rock
that makes up the oceanic crust.
10. Midocean ridges reach a typical summit elevation of ___________ meters below sea level. They
are the shallowest major features of the seafloor. The oceans are ________________ closer to
continents and farthest from midocean ridges.
11. Seafloor spreading is one of the two major processes of _________________________, the
other being subduction.
12. Seafloor spreading produces major characteristics of the seafloor - 1) the age of the seafloor is
progressively _____________ away from midocean ridges, 2) the elevation of the seafloor is
progressively _____________ away from midocean ridges, 3) the magnetic history of the seafloor
bears the ___________________ of the Earth's magnetic reversals, and 4) _____________ parts of
the seafloor have the greatest potential to have accumulated sediments over the longest time.
13. Since the seafloor on each side of a midocean ridge moves in opposite directions, each side
belongs to a different ______________________.
14. Seafloor spreading determines plate motion around a midocean ridge. Midocean ridges are
always _______________________. Since many plates, such as the North American Plate, include
continental portions attached to oceanic portions, seafloor spreading also happens in the direction in
which continents move. Continents don't drift independently. _____________ moves to the west with
the western half of the Atlantic.

the form of ___________________________________________) quickly replaced wood, wind,
solar, and water as the main sources of fuel.
