The Ocean Floor Is Generally Lower Than The Continents Because

Identify the statement that is true about the ocean floor.

The ocean floor is generally lower than the continents because. The correct answer is option c that is 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 felsic minerals and is heavier than continental material. They may be very close or parallel to the continents bordered by fold mountains.

It is covered by a layer of sediment composed of sand and pebbles. Oceanic crust is thinner and denser than continental crust. Which of the following pieces of evidence best supports this claim. The collision of two plates takes place with each other in the phenomenon of convergent plate tectonics.

The ocean deeps are the deepest part of the ocean. Ocean floor subducts under continents because a the ocean floor has a lower density and therefore sinks more easily. The ocean floor subducts under continents because a the ocean floor has a lower density and therefore sinks more easily. Gravitational force is stronger beneath the continental crust.

During rifting continental margins are heated but cool as sea floor spreading moves offshore from the continent. The flat deep portions of the ocean floor. C the ocean floor is made of mafic material and is therefore more dense than continental material. Oceanic crust is thinner and denser than continental crust.

Oceanic crust has a lower density than continental crust has. Oceanic crust contains granite and metamorphic rocks. The answer is c. B the ocean floor is made of mafic material and is therefore more dense than continental material.

In the interior of continents the earth s crust is typically about 40km thick and the elevation is near sea level. The heavier and denser plate gets sink underneath the lighter plate. The ocean floor is at a lower elevation than the continents. Due to the action of plate tectonics ocean crust is being formed and destroyed continuously.

Flat topped underwater features found at least 1000 m below the surface. They are usually found adjacent to the areas of volcanic and earthquake activity. Steep sided volcanoes on the ocean floor that may breach the surface. Tectonic plates located below the continental crust do not move.

Very common features less than 1000 m high guyots. Most earth materials expand when heated lowering their density. C the ocean floor is made of felsic minerals and is heavier than continental material.
