Hello my name is Ms. Kaya I am from a plate tectonic research lab. I am here to talk to you about the carbon cycle and how it affects climate change. Lets begin!
melted crust contains carbon in the sediments and soils, and recycles it through the mantle. it will resurface as lava, the volcanoes were formed by tectonic forces. CO2 is then released by the eruption into the atmosphere.
crust containing carbon can be recycled through the mantle, and released through a ridge, convergent or divergent. Rainfall pulls CO2 out of the air, in turn reducing the amount CO2 in the atmosphere lowering global temp. Glaciation occurs, and white ice has a high albedo reflecting solar energy back into space. continuing to reduce temp.
As the earth continues to cool, cold dry air halts the growth of the glaciers, creating deserts. the air then becomes so dry that little to nothing of rainfall occurs, so the CO2 released from volcanoes is kept in the atmosphere.
the carbon then accumulates and begins to trap the infrared waves of the sun in the greenhouse effect, eventually increasing the global temp.
the large amount of carbon in the atmosphere can combine with the water being evaporated into the atmosphere and form carbonic acid. Water then carries the bicarbonate and the other ions into the ocean where they form carbonate sediment.
Plate tectonics, through the formation of volcanoes, works with the carbon cycle. Tectonic forces release carbon through degassing and entrap carbon during subduction. the relationship most occurs with the breakup of continents and the resulting affect on climate.
this is how the carbon cycle and plate tectonics relates.
