10 Questions
What was the initial uncertainty about the formation of the underwater ridge system?
Whether the ridge was a tectonic plate boundary
What did the thin layers of sediment near the ridge crest and thicker sediment farther away indicate?
Different time periods of existence
What did the samples taken from the ridge system reveal about the age of rocks near and away from the crest?
Rocks near the crest were very young, getting older farther away
What did the theory of seafloor spreading propose?
New oceanic crust is constantly formed due to upwelling magma through diverging tectonic plates
What did the evidence from drilling samples provide strong support for?
The theory of plate tectonics and moving tectonic plates
What is plate tectonics?
The theory that the earth's crust is broken up into plates
What was the purpose of the Deep Sea Drilling Project (DSDP)?
To analyze the ocean floor by drilling core samples

Glomar Challenger
What important feature is found on the Atlantic Ocean basin?
Mid-Atlantic Ridge
What did the Deep Sea Drilling Project (DSDP) aim to extract from the ocean floor?
Samples of ocean sediments and underlying oceanic crust
