Description: Sequence of images in the Eocene showing the location of the continents during this time. The point here is that platetectonics plays a major roll in determining the climate change necessary to happen for continental ice sheets to appear. Australia and Drake passages are closed during the Eocene blocking cold water circulation. Panama passage is open allowing circulation of low latitude warm waters. India-Asia collision will be important for the cooling trend in the future.
