What was one of the results from the data gathered during deep ocean drilling?
As for the purpose of the scientific exploration, one of the most important discoveries was made when the crew drilled 17 holes at 10 different locations along an oceanic ridge between South America and Africa. The retrieved core samples provided strong proof for continental drift and seafloor renewal at rift zones.
What is the purpose of deep sea drilling?
The Deep-Sea Drilling Project (DSDP) was a scientific program for drilling cores of sediment and basaltic crust beneath the deep oceans and recovering them for study.
Why would a geologist want to drill into the ocean floor?
The practice of boring holes in the sea floor has revolutionized earth science, helping researchers to confirm the theory of plate tectonics, discover microbes deep in the ocean crust and probe the hidden risks of earthquakes and tsunamis.
Which of the following is evidence for sea floor spreading?
Several types of evidence supported Hess’s theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves.
What does evidence from ocean drilling for sediment cores support?
Ocean drilling cores have been used to confirm the age of the oldest oceanic crust, which was formed about 180 million years ago. Because it is much younger than the age of the Earth, this discovery further supported the concept that oceanic crust created at mid-ocean ridges is eventually recycled at subduction zones.
How did ocean drilling prove the theory of plate tectonics?
The Deep Sea Drilling Project (DSDP) was an ocean drilling project designed to analyze the ocean floor. This showed that new oceanic crust was being formed along the plate boundary and then spreading out laterally, providing evidence to support the theory of seafloor spreading and plate tectonics.
How did drilling prove plate tectonics?
Do we drill at the bottom of the ocean?
Today scientists from 23 nations are proposing and conducting research through the International Ocean Discovery Program, which uses scientific ocean drilling to recover data from seafloor sediments and rocks and to monitor environments under the ocean floor.
What were three types of evidence that supported Hess’s theory of sea floor spreading?
Several types of evidence from the oceans supported Hess’s theory of sea-floor spreading-evidence from molten material, magnetic stripes, and drilling samples.
What is the major evidence that sea floor spreading creates new lithosphere?
The record of magnetic reversals is carried away from each side of the spreading center of a mid-ocean ridge, showing that the molten rock is creating new lithosphere.
What can be learned from drilling into the sediment at the bottom of the ocean?
Scientific ocean drilling has spurred remarkable progress in understanding many global processes: confirming the theory of plate tectonics, documenting the history of Earth’s cli- mate system, investigating the role of fluid flow within the ocean crust, and discovering an extensive subseafloor biosphere that may well …
What are the three evidences of seafloor spreading?
What was the evidence for the spreading of the seafloor?
Harry Hess’s hypothesis about seafloor spreading had collected several pieces of evidence to support the theory. This evidence was from the investigations of the molten material, seafloor drilling, radiometric age dating and fossil ages, and the magnetic stripes. This evidence however was also used to support the Theory of Continental drift.
When did scientists start drilling the ocean floor?
When scientific ocean drilling began in 1968, the theory of plate tectonics was a subject of active debate. One key idea was that new ocean crust was created at ridges in the seafloor, where…
How does deep sea drilling support plate tectonics?
The Deep Sea Drilling Project extracted samples of the ocean floor that provided evidence to support the hypothesis of seafloor spreading and the theory of plate tectonics.
What did the drill do to the seafloor?
At the end of the pipes was a drill that cut into the seafloor. The system collected long, thin cylinders (meters long and centimeters wide) of sediment and rock from beneath the seafloor, called cores. The cores provided evidence to confirm seafloor spreading and plate tectonics, but they also revealed much more.
