The Deep Sea Drilling Project

The purpose of the DSDP was to analyze the ocean floor.

The DSDP began in the 1960s.

Plate tectonics is the theory that the earth's crust is broken up into plates.

<p>Drilling the Mid-Atlantic Ridge was important because at the time it was not fully understood how this large underwater ridge had formed.</p> Signup and view all the answers

<p>Seafloor spreading is the theory that new oceanic crust is constantly being formed due to the upwelling of magma through diverging tectonic plates.</p> Signup and view all the answers

<p>The evidence that supported the theory of seafloor spreading was the discovery of young rocks near the crest of the ridge and older rocks farther away, as well as the observation of thinner sediment layers near the crest and thicker layers farther away.</p> Signup and view all the answers

<p>The samples taken from the Mid-Atlantic Ridge showed that new oceanic crust was being formed along the plate boundary and then spreading out laterally, providing evidence for the theory of plate tectonics.</p> Signup and view all the answers
