for better research go to under NOAA - Climate.gov
This is a short paraphrased summary of the article about ice cores in that website.
Answer: Researchers in labs may melt or crush bits of the ice core a little at a time, each deeper layer shows the time in the Earth's climate history. Tiny pieces of pollution, metals, radoiactive fallout, pebbles, sea salt, volcanic ash and even air bubbles all present important information that researchers can look for to track changes in the atmosphere's composition and temperature.

Answer:
Temperature and pressure
Explanation:
mechanical weathering is the disintegration/breakdown of rocks and this mainly caused the agents of mechanical weathering which are ; water , wind and ice, and this agents of mechanical weathering achieve this due the factors Temperature and pressure.
Temperature : The continuous heating and cooling of rock surfaces cause s wear and tear on the rocks leading to mechanical weathering
pressure : Ice water found in cracks of rocks exert pressure on the rocks and this also causes the rocks to disintegrate overtime
