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