Process That Creats New Ocean Floor

New material forms on the ocean floor of the mid ocean ridge due to plate tectonics and volcanic activity.

Process that creats new ocean floor. This spreading creates a successively younger ocean floor and the flow of material is thought to bring about the migration or drifting apart of the continents. What features are formed on the continent along this boundary. The lava will then wells up and hardens causing the ocean floor to be pushed away from either side of the ridge. Since the new oceanic basins are shallower than the old oceanic basins the total capacity of the world s ocean basins decreases during times of active sea floor spreading.

Ocean floor spreading ocean floor spreading happens when volcanic and earthquake activity occurs at the mid ocean ridges. Plate tectonics and the ocean floor. The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. On the other hand the older ocean floor that is pushed away from the.

These creatures live in very demanding environments. What is the process that creates new ocean floor from diverging plates. Lava from rift valley runs through the ridge. The hardened lava forms new ocean floor.

During the opening of the atlantic ocean sea level was so high that a western interior seaway formed across north america from the gulf of mexico to the arctic ocean. These creatures must survive in extremely harsh conditions such as hundreds of bars of pressure small amounts of oxygen very little food no sunlight and constant extreme cold. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle. Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around.

Name a specific location. What is the process called that creates new ocean floor from diverging plates. It melts into magma 2. 1 what happens when a tectonic plate gets subducted.

The continents bordering the atlantic ocean for example are believed to be moving away from the mid atlantic ridge at a rate of 1 2 cm 0 4 0 8 inch per year thus increasing. Volcanic eruptions deposit cooled magma on the ocean floor. The process by which new material is added to the ocean floor along the boundary between diverging plates.
