Sea Floor Spreading Rate Hypothesis And Co2

Tectonic control of co2.

Sea floor spreading rate hypothesis and co2.

These age data also allow the rate of seafloor spreading to be determined and they show that rates. Sea floor spreading. Seafloor spreading theory that oceanic crust forms along submarine mountain zones known collectively as the mid ocean ridge system and spreads out laterally away from them. This theory focuses the control of co2 levels on plate tectonic processes.

Sea floor spreading volcanic activity co2 increase co2 change in the last 100 myr. Spreading rates determine if the ridge is fast intermediate or slow. 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. During plate tectonics carbon is cycled endlessly between the earth s.

This theory focuses the control of co2 levels on plate tectonic processes. Blag hypothesis or spreading rate hypothesis climate changes have been driven mainly by changes in the rate of co2 input to the atmosphere and ocean by plate tectonic processes. 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. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.

The seafloor spreading theory is one hypothesis introduced to suggest a mechanism of controlled co2 levels in the atmosphere causing the observed variations between warm co2 rich greenhouse intervals and cold co2 depleted global cooling intervals. 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. The seafloor spreading theory is one hypothesis introduced to suggest a mechanism of controlled co2 levels in the atmosphere causing the observed variations between warm co2 rich greenhouse intervals and cold co2 depleted global cooling intervals.
