Answer:

1 A,  2 B.

Explanation:

1. In carbonization, a thin film of carbon mineral is formed on the fossils, giving them a dark black coloration, which makes us conclude that the fossils observed are an example of carbonization.

2. The presence of tropical swamp plant impressions in polar regions is an indication of a different, likely warmer climate in the past, in the polar regions, because plants commonly grow in similar conditions as their living counterparts and no tropical swamp plants are known that can live in polar regions today. Lichens that live in the tundra are not real plants.
