20 Questions
What is the purpose of the Deep Sea Drilling Project (DSDP)?
The purpose of the DSDP was to analyze the ocean floor.
When did the Deep Sea Drilling Project (DSDP) begin?
The DSDP began in the 1960s.
What is plate tectonics?
Plate tectonics is the theory that the earth's crust is broken up into plates.
What are tectonic plates?
Tectonic plates are the broken up pieces of the earth's crust that float on the layer below.
How do tectonic plates move?
Tectonic plates can push together, pull apart or slide past each other.
What kind of stories are often about journeys at sea?
Classic stories often involve journeys at sea.
What is one classic story that involves a journey at sea?
One classic story that involves a journey at sea is Homer's Odyssey.
What is another classic story that involves a journey at sea?
Another classic story that involves a journey at sea is Gilligan's Island.
What is the Mid-Atlantic Ridge?
The Mid-Atlantic Ridge is a part of the ocean floor where new crust is formed.
What is seafloor spreading?
Seafloor spreading is the process by which new crust is formed at the Mid-Atlantic Ridge and pushes the older crust away.
What was the purpose of the Glomar Challenger?
The purpose of the Glomar Challenger was to drill down into the ocean floor and extract samples of the ocean sediments and underlying oceanic crust.
What is the Mid-Atlantic Ridge?
The Mid-Atlantic Ridge is an underwater mountain range that runs from Iceland to Antarctica.
Why was drilling the Mid-Atlantic Ridge important?
Drilling the Mid-Atlantic Ridge was important because at the time it was not fully understood how this large underwater ridge had formed.
What is seafloor spreading?
Seafloor spreading is the theory that new oceanic crust is constantly being formed due to the upwelling of magma through diverging tectonic plates.
What evidence supported the theory of seafloor spreading?
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.
What is plate tectonics?
Plate tectonics is the theory that the Earth's crust is made up of moving tectonic plates.
How did the samples taken from the Mid-Atlantic Ridge provide evidence for plate tectonics?
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.
What was the purpose of the Deep Sea Drilling Project (DSDP)?
The purpose of the Deep Sea Drilling Project (DSDP) was to analyze the ocean floor.
What did the samples taken from the Mid-Atlantic Ridge show about the age of the rocks?
The samples taken from the Mid-Atlantic Ridge showed that rocks near the crest of the ridge were very young, and they got older farther away from the crest.
