Model Of Sea Floor Spreading

The age spreading rate and asymmetry at each grid node is determined by linear interpolation between adjacent seafloor isochrons in the direction of spreading.

Current sea floor spreading rate. These age data also allow the rate of seafloor spreading to be determined and they show that rates. A linear ridge of sediment attached to land at one end might be called a. Ages for ocean floor between the oldest identified magnetic anomalies and continental crust are interpolated by geological estimates of the ages of passive continental margin segments. Lab worksheets for each student edition activity laboratory sea floor spreading project answer key lab 4 sea floor spreading lab seafloor spreading.

The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate. Whats people lookup in this blog. 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. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.

Your response would probably be to. R d t or r 9 5 10 7 cm 6 5 10 7 years 1 46 cm yr. Seafloor spreading rates lab answer key. 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.

As upwelling of magma continues the plates continue to diverge a process known as seafloor spreading samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre important evidence in favour of this process. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. When seafloor spreading rates increase. There is a rise in sea level.

Ages for ocean floor between the oldest identified magnetic anomalies and continental crust are interpolated by geological estimates of the ages of passive continental margin segments. Lab seafloor spreading rates answers. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. The age spreading rate and asymmetry at each grid node are determined by linear interpolation between adjacent seafloor isochrons in the direction of spreading.

Ranges of spreading throughout the world s oceans. Lab seafloor spreading rates worksheet answers. Measure from the center of the spreading center to a known age point on the plate rather than from 65 ma on the eastern plate to 65 ma on the western. 1cm yr to 10 cm yr.
