Trenches to develop on the ocean floor.

Explain the ocean floor configuration with the help of diagram class 11.

By the late 1960s several american investigators among them jack e. The ocean floor is thus pushed at right angles and in opposite directions away from the crests. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. The red colors are the youngest parts of the seafloor where fresh new crust is formed as lava seeps up from the deep interior of the earth at spreading ridges.

The chief cause of a volcano is disturbances in earth s crust. It is the bottom of the ocean when you dive. Continental shelf is the shallow portion of the ocean which lies close to the continental margin. Gives examples of living resources from the ocean floor.

Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. It is actually a part of the continent sloping. Explain the rock cycle with the help of diagram 17. Oliver and bryan l.

Identify nonliving resources on or below the ocean floor. Isacks had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory. In the following diagram there is evidence of seafloor spreading by showing the ages of the ocean floor. 11 the ocean floor.

Oceanography compound of the greek words ὠκεανός meaning ocean and γράφω meaning write also known as oceanology is the study of the physical and biological aspects of the ocean it is an important earth science which covers a wide range of topics including ecosystem dynamics. Not too many people have gone to the floor of the ocean as it requires special diving equipment.

The ocean floor is literally the floor of the ocean. Explain the continental drift theory given by alfred wegener. This video examines the different types of features in the ocean primarily on the ocean floor. All this evidence both from the ocean floor and from the continental margins made it clear around 1965 that continental drift was feasible and the theory of plate tectonics which was defined in a series of papers between 1965 and 1967 was born with all its extraordinary explanatory and predictive power.

Explain the ocean floor configuration with the help of diagram. Relate features of the ocean floor to plate tectonics. Plate tectonics and the geology of the sea. Explain tectonic plate theory and its working.
