I had this question I think it’s gamma rays
Answer: Option A.
Polar ice cap in Antarctica.
Explanation:
Scientist drill ice cores from inside the polar ice cap in Antarctica to study variability of climate and differentiate that variability From global climate change. Each layer of the ice tells about weather and what the Earth was like when the first snow fell.
For example, Le grande says that as snow deposits into a growing glacier, the temperature of the air imprints on water molecules.
Icy layers hold particles,aerosols, sea salts, trace elements that were in the atmosphere before and they abide for thousands of years and provide evidence of past events.
