How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
How does offshore drilling differ from drilling on land?
One is in the ocean and one is on land. It is pretty obvious!
How was the age of rocks in ocean basins determined?
Drilling.
Strips of alternating magnetic polarities found in rocks in the ocean basins?
provide evidence for sea-floor spreading
What are some features of the ocean floor that provide evidence for plate tectonics?
they found fossils
What geographical features provide evidence for plate tectonics?
Mountains, Valleys, Sea Floor Spreading, Trenches in the Ocean!
How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges
What is evidence that our planet has plates tectonics?
Chains of volcanos along ocean Coastlines
What are two pieces evidence for cracks in the ocean floor?
molten material and drilling samples
How do ocean basin magnetic reversals prove plate tectonics exists?
They technically don't. They do provide evidence for it, however, in that they occur in pairs on either side of a rift, providing strong evidence that the rocks on either side were deposited at the same time and that the rifts are spreading.
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
What evidence didn't Wegnerhave access to at the time?
Evidence for continental drift, now called tectonics, arrived with the discovery of the mid-ocean ridge, where new crust is being created.
Where on the ocean floor does oil drilling take place?
Oil drilling often occurs on the seabed, that is, the very bottom of the ocean.
Which of jupiters moons surface features provide evidence of a subsurface liquid ocean?
Europa...
What were the goals of the deep sea drilling project?
To investigate the evolution of ocean basins by core drilling of ocean sediments and underlying oceanic crust.
How sea floor spreading provide evidence for tectonic plates?
by the plate tectonic and the ocean bridges
