picks up chemicals and particulate matter that is present and brings it to the ground (Roach, 2004). Layer after layer of snow becomes compacted into ice, leaving behind a
trail of information related to climate change noted by the presence of different chemicals and substances deposited in the layers of ice (Roach, 2004). In the Antarctic, scientists
are retrieving ten-foot ice cores that provide information about changing climate and physical conditions looking back approximately 1 million years (Roach, 2004). Retrieved in 10 foot segments that
are six inches in diameter, the ice cores are provide information in the following manner: One of the limitations of ice core data is that it only
goes back approximately 1 million years. Roach (2004) states that this is because the "deepest ice moves laterally to the edge of the continent," the older ice spreads out
"like a ladle of pancake batter poured on a griddle." As a result, the oldest ice cores with accurate information go back 1 million years. Researchers, though, maintain
that this kind of physical data over the course of 1 million years helps provide information about climate changes, the presence of a variety of chemicals, and specific catastrophic events,
which can be demonstrated in the layers of ice. Ice cores, then, are a chronological record of global climate changes (Roach, 2004). Topic 2 The answer
to what has caused the Ice Ages over the past 2.5 million years has been at the center of paleoclimatology and focus on three specific factors: tectonic forcing, orbital forcing
and understanding Glacial/Interglacial cycles. Understanding each of these elements and their impact on existing research helps to show the varied views on how the Ice Ages occurred. Ruddiman and
