The Sea Floor Is Constantly Shrinking

The atlantic is growing as a result of seafloor being added along the mid ocean ridge that runs its length.

The sea floor is constantly shrinking.

Explain the following statement. In about 500 million years the pacific will not be there and the. Rising magma cools and solidifies to form new rock that replaces the ocean floor. Search for an answer or ask weegy.

Because of sea floor spreading the ocean floor is constantly renewing itself. The seafloor is constantly shrinking. It makes up 28 of the earth s surface and is home to the world s deepest oceanic trench the mariana trench. Seafloor spreading is the continuous process of forming new igneous rock at mid ocean ridges by injection of magma that forms new seafloor.

Vl hat happens at deep ocean trenches. The pacific is neither growing nor shrinking. The pacific ocean is the world s largest ocean. It is also shrinking because of plate tectonics.

But the pacific ocean is slowly shrinking at a rate of 0 5 square kilometers 0 19 square miles per year due to plate tectonics. Vi hat is the evidence for sea floor spreading. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. When the weight of an area of earth s crust increases the lithosphere.

Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. Asked 3 29 2017 1 32 49 pm. It is massive with an estimated area of 63 8 million square miles and an average depth of 13 000 feet. The seafloor is constantly shrinking.

The reason the pacific ocean is shrinking is because of the deep water trenches there while the atlantic ocean is getting bigger. This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century. In the mid 1900s scientists mapped the mid ocean ridges using sonar. The process is continuous because forces cause opposite sides of the mid ocean ridge to constantly move apart making new room for the process to repeat.

Ii hat is the process of sea floor spreading. Log in for more information. The mid atlantic ridge for instance separates the north american plate from the eurasian plate and the south american plate from the african plate the east pacific rise is a mid ocean ridge that runs through the eastern pacific ocean and separates the pacific plate from the north american.
