Why do you think geologists might find Iceland a useful?
why might geologists find Iceland a useful place to conduct research on seafloor spreading? scientists suggest that differences in density cause hot, plasticlike rock to be forced upward toward the surface, cool, and sink.
What geological feature is formed at the two side slits?
Scientists determined that the same process formed the perfectly symmetrical stripes on both side of a mid-ocean ridge. The continual process of seafloor spreading separated the stripes in an orderly pattern. Oceanic crust slowly moves away from mid-ocean ridges and sites of seafloor spreading.
Where are the youngest sediments found compared to the mid Atlantic ridge answer?
opening of
Why is the center of the Atlantic shallower than the areas closer to the continents?
Question: Why is the center of the Atlantic Ocean shallower than areas closer to the continents? Oceanic plates collide at this location, making submarine mountains c. Newly formed crust at this location is much hotter than older crust d.
What are three pieces of evidence of seafloor spreading?
Look at Figure 19 to see the process 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 happens to magma that rises through cracks on the seafloor?
The process is called sea-floor spreading. Ridges form along cracks (divergent boundaries) in the oceanic crust (Molten rock (magma) rises through these cracks and pushes to both sides. When it cools, it forms new oceanic crust. The old crust is pushed away and new crust takes over.
Which information did the Glomar Challenger study in 1968?
ANSWER: Glomar Challenger studies about the “age of rocks in various places in the ocean” in 1968. EXPLANATION: Glomar Challenger was a “deep sea research vessel” for marine geology and oceanography studies.
What does the presence of new rock near an oceanic ridge indicate Brainly?
There is always a deep-sea trench underneath. There is evidence of seafloor spreading. They are made from oceanic crust.
Which is one piece of evidence of seafloor spreading quizlet?
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. an undersea mountain chain where new ocean floor is produced.
Which best describes all new rocks that form near ocean ridges?
The best answer would be – option A. have a striped pattern. Explanation: Oceanic ridge is the geographic location or region which occurs with the seafloor spreading.
Which feature of Earth is created at mid-ocean ridges?
Explanation: Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
Which types of evidence do geologists usually study?
Geologists have used two main types of evidence to learn about Earth’s interior: direct evidence from rock samples and indirect evidence from seismic waves. The geologists are observing rock on Earth’s surface.
