4.2     Impacts

Impacts of climate changes in the history of the Earth are recorded in the layers of rock, the ice cores from the polar ice capes, and the pollen cores from lake bottoms.

The landscape tells us:
where glaciers were and how they moved
how long the glacial periods were
where the great water courses were and how they changed.

The fossil records tell us what life forms existed before and after each massive climate change.

The geological time scale is included here as an index to the history book of the Earth. It helps us remember the order of the changes that occurred

4.2.1. Impacts on Lithosphere (Land)
4.2.2. Impacts on Hydrosphere (Water)
