Summary
[edit]DescriptionAntarctic snow pit.jpg |
English: This covered snow pit in Antarctica is illuminated by sun light shining through the snow from an adjacent pit. The dark layers are winter snow and the light layers are summer snow. The chemicals and gases in the layers record the climate conditions and are used to reconstruct how and why climate changed in the past. |
