Plate tectonics and carbon cycle
This storyboard does not have a description.
Pangea breaks up into smaller continents 770 ma ago.
In subduction zones, the oceanic plate builds magma and pressure.
Volcanos erupt, and carbon is released into the atmosphere during degassing.
Moist air causes lots of rain, reducing carbon dioxide and causing cooling temperatures.
Sun rays reflect off the white glacier ice and temperatures cool more.
Cold dry air stops glaciers forming and deserts form instead. Without rain, carbon dioxide builds in the air, greenhouse effect occurs and temperatures rise.
Carbon in the atmosphere combines with rain and makes carbonic acid, which erodes rocks and causes carbon sediment in oceans.
