ADDRESSING THE QUESTION ESSAY FEEDBACK Show how the study of isotopes has been crucial in shaping our understanding of Quaternary environmental change
If minor variations in the orbital behaviour of the Earth appear to have been the "Pacemaker of the Ice Ages" (Berger, 1992) during the Quaternary, why has the Earth not experienced repetitive glaciations throughout its entire history?
'The study of isotopes has proved crucial to the establishment of a coherent framework of Quaternary climate change.' Discuss. Past exam questions... Discovery Group 1:
reconstruct a climate history of the Sahara for determining when it was wet and where for the purposes of investigating human migration out of Africa
Timespan: 125,000 years
Budget: £2 million
reconstruct a history of precipitation in Huashan, north-central China during the Holocene
Timespan: 10,000 years
determine how often the Earth experienced glacial periods during the Quaternary and what caused them
Timespan: 2,000,000 years
Budget: £12 million
