1) quiz

1 What dynamic process produces new oceanic lithosphere?

A sea floor spreading
B erosion of ocean ridges
C underwater volcanoes

B Rocks all along the ridges are a consistent age.
C Rocks at the crest of the ridge are old; rocks found further from the crest are younger.
D Rocks at the crest of the ridge are much hotter than rocks found elsewhere.

B The ocean floor only appeared about 180 million years ago.
C The ocean floor was only discovered relatively recently.
D The rate of sea floor spreading is rapid enough to recycle the ocean floor in a 4 billion year cycle.

B mid-ocean ridges
C guyots
D deep ocean trenches
