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