The Ocean Floor Is Generally Lower Than The Continents Because

C the ocean floor is made of felsic minerals and is heavier than continental material.

The ocean floor is generally lower than the continents because.

Flat topped underwater features found at least 1000 m below the surface. The heavier and denser plate gets sink underneath the lighter plate. 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.

Tectonic plates located below the continental crust do not move. Oceanic crust contains granite and metamorphic rocks. It is covered by a layer of sediment composed of sand and pebbles. The correct answer is option c that is oceanic crust is thinner and denser than continental crust.

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. 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.

Oceanic crust has a lower density than continental crust has. They are generally called submarine trenches. B the ocean floor is made of mafic material and is therefore more dense than continental material. The answer is c.

Which of the following pieces of evidence best supports this claim. Most earth materials expand when heated lowering their density. These trenches are not always located in the middle of the ocean basins. Oceanic crust is thinner and denser than continental crust.

The heat flow through it is greatest at mid ocean ridges. Oceanic crust is thinner and denser than continental crust. The ocean deeps are the deepest part of the ocean. The ocean floor is at a lower elevation than the continents.

Very common features less than 1000 m high guyots. C 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. B 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 flat deep portions of the ocean floor. The oldest oceanic crust is about 200 million years old whereas continents which are less dense than.
