It might be due to abiotic factors like the temperature or soil at high altitude or due to some biotic factor like a mutualistic relationship with organisms at high altitudes. Hence, option C is the correct option.
air bubbles
Explanation:
Ice cores are useful in determining the composition of the atmosphere in the past because they contain air bubbles which can be analysed to better understand past climatic conditions.
Air bubbles are a key component of ice cores. They form when thick sequence of ice are are collected. In between their cavities, bubbles are often trapped.
These bubbles are so preserved in the crystal shapes of the ice.
They give good clues about the composition of the atmosphere in times past.
They are usually dug during drilling expedition
