The Ocean Floor Is Generally Lower Than The Continents Because

The ocean floor subducts under continents because a the ocean floor has a lower density and therefore sinks more easily.

The ocean floor is generally lower than the continents because.

It is covered by a layer of sediment composed of sand and pebbles. Oceanic crust is thinner and denser than continental crust. These trenches are not always located in the middle of the ocean basins. The flat deep portions of the ocean floor.

Ocean floor subducts under continents because a the ocean floor has a lower density and therefore sinks more easily. During rifting continental margins are heated but cool as sea floor spreading moves offshore from the continent. Very common features less than 1000 m high guyots. The correct answer is option c that is oceanic crust is thinner and denser than continental crust.

They may be very close or parallel to the continents bordered by fold mountains. Oceanic crust is thinner and denser than continental crust. C the ocean floor is made of mafic material and is therefore more dense than continental material. The heat flow through it is greatest at mid ocean ridges.

Oceanic crust contains granite and metamorphic rocks. They are usually found adjacent to the areas of volcanic and earthquake activity. The collision of two plates takes place with each other in the phenomenon of convergent plate tectonics. B the ocean floor is made of felsic minerals and is heavier than continental material.

In the interior of continents the earth s crust is typically about 40km thick and the elevation is near sea level. They are generally called submarine trenches. The answer is c. The ocean floor is at a lower elevation than the continents.

Gravitational force is stronger beneath the continental crust. Flat topped underwater features found at least 1000 m below the surface. Which of the following pieces of evidence best supports this claim. C the ocean floor is made of felsic minerals and is heavier than continental material.

Identify the statement that is true about the ocean floor. 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. Oceanic crust has a lower density than continental crust has.

The ocean deeps are the deepest part of the ocean. Steep sided volcanoes on the ocean floor that may breach the surface. Due to the action of plate tectonics ocean crust is being formed and destroyed continuously.
