A number of major features of the basins depart.
Explain the ocean floor configuration in terms of major and minor decisions with diagram.
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.
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.
Mid ocean ridges trenches and large faults mark the edges of the plates and this is where earthquakes occur figure 1.
Ocean relief features are divided into major and minor relief features.
A large depression in the earth s surface filled with seawater.
What tool was used to do this mapping.
Continental drift and sea floor spreading became widely accepted around 1965 as more and more geologists started thinking in these terms.
This actually led to research on the ocean floor that would help explain the movement of the continents.
Studies of living things.
Major mountain chains form inside continents or near their edges.
Major ocean relief features four major divisions in the ocean relief are.
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.
In 1961 and 1962 scientists proposed the process of seafloor spreading caused by mantle convection to explain the movement of the earth s.

The development of submarine warfare druing world war ii created a pressing need to map the ocean floor.
The plates edges can be drawn by connecting the dots that mark earthquakes epicenters.
The alvin and the trieste are two famous examples.
Most earthquakes and volcanoes occur in bands that are often along the boundaries between continents and oceans.
