Oceanic crust contains granite and metamorphic rocks.
The ocean floor is generally lower than the continents because.
Oceanic crust has a lower density than continental crust has.
Very common features less than 1000 m high guyots.
The ocean floor subducts under continents because a the ocean floor has a lower density and therefore sinks more easily.
Oceanic crust is thinner and denser than continental crust.
The heavier and denser plate gets sink underneath the lighter plate.
The flat deep portions of the ocean floor.
Tectonic plates located below the continental crust do not move.
Ocean floor subducts under continents because a the ocean floor has a lower density and therefore sinks more easily.
The ocean deeps are the deepest part of the ocean.
C the ocean floor is made of mafic material and is therefore more dense than continental material.
They are generally called submarine trenches.
C the ocean floor is made of felsic minerals and is heavier than continental material.
Gravitational force is stronger beneath the continental crust.
The ocean floor is at a lower elevation than the continents.
The answer is c.
B the ocean floor is made of mafic material and is therefore more dense than continental material.
Flat topped underwater features found at least 1000 m below the surface.
In the interior of continents the earth s crust is typically about 40km thick and the elevation is near sea level.
Due to the action of plate tectonics ocean crust is being formed and destroyed continuously.
During rifting continental margins are heated but cool as sea floor spreading moves offshore from the continent.
They may be very close or parallel to the continents bordered by fold mountains.
The collision of two plates takes place with each other in the phenomenon of convergent plate tectonics.
Which of the following pieces of evidence best supports this claim.
They are usually found adjacent to the areas of volcanic and earthquake activity.
B the ocean floor is made of felsic minerals and is heavier than continental material.
The oldest oceanic crust is about 200 million years old whereas continents which are less dense than.
The heat flow through it is greatest at mid ocean ridges.
Steep sided volcanoes on the ocean floor that may breach the surface.
Most earth materials expand when heated lowering their density.
The correct answer is option c that is oceanic crust is thinner and denser than continental crust.
Identify the statement that is true about the ocean floor.
