Answer:event that occured billions of years ago- oxygen building up in earths atmosphere
Event that occured thousands of years ago- the last ice age
Event occured decades ago- carbon dioxide levels
Which factor should be included in a model of energy flow into the atmosphere- concentrations of green house gases
How does climate change affect energy in the atmosphere- decreased ice causes less energy
Ocean acidification- difficult for species to make shells,larger concentration of carbon acid,organisms more prone to illness
Ocean warming- melting glaciers, expansion of ocean volume,difficulty absorbing carbon dioxide
Which effect of temperature rise causes a feedback resulting in a rise in global temperatures- more water vapor in atmosphere
Scientist believe that the MILANKOVITCH CYCLES explain why earths CLIMATE HAS fluctuated between glacial periods and interglacial periods
What does a model of the rock cycle show- the amount of earth carbon is constant
What does a wider tree ring indicate- indicates the weather that year was warm and wet
