Ocean basin any of several vast submarine regions that collectively cover nearly three quarters of earth s surface.
Explain the ocean floor configuration in terms of major and minor decisions with diagram.
Together they contain the overwhelming majority of all water on the planet and have an average depth of almost 4 km about 2 5 miles.
A small depression in the ocean floor.
Most earthquakes and volcanoes occur in bands that are often along the boundaries between continents and oceans.
The continental shelf the continental slope the continental rise the deep sea plain or the abyssal plain.
Ocean relief ocean relief is largely due to tectonic volcanic erosional and depositional processes and their interactions.
Bathyscaphe a relatively small maneuverable submersible vessel specially constructed to withstand enormous pressure and used to explore the deep ocean floor.
This actually led to research on the ocean floor that would help explain the movement of the continents.
What tool was used to do this mapping.
The minor fracture zones intersect the axis of the mid atlantic ridge in an asymmetric v shaped configuration.
The landscape of the ocean floor is much like what you see on land just way more dramatic and without all that life.
The ocean floor is literally the floor of the ocean.
Mid ocean ridges trenches and large faults mark the edges of the plates and this is where earthquakes occur figure 1.
Earthquake epicenters outline the plates.
The lithosphere is divided into a dozen major and several minor plates figure 2.
Major mountain chains form inside continents or near their edges.
In 1961 and 1962 scientists proposed the process of seafloor spreading caused by mantle convection to explain the movement of the earth s.
A large depression in the earth s surface filled with seawater.
The plates edges can be drawn by connecting the dots that mark earthquakes epicenters.
By the 1960s holmes idea began to gain more credibility as scientists increased their understanding of the ocean floor via mapping discovered its mid ocean ridges and learned more about its age.
An asymmetric pattern is observed in the orientation of minor fracture zones about the axis of the mid atlantic ridge at five sites where relatively detailed studies have been made between latitudes 22 n and 51 n.
The major plates are eurasia pacific india australia north america south america africa and antarctic.
Continental drift and sea floor spreading became widely accepted around 1965 as more and more geologists started thinking in these terms.
Ocean relief features are divided into major and minor relief features.
By the end of 1967 earth s surface had been mapped into a series of plates figure 10 16.
A number of major features of the basins depart.
The alvin and the trieste are two famous examples.
The locations of mountain ranges deep ocean trenches ocean floor structures earthquakes and volcanoes occur in patterns.
