Climate Change
1) Fossils of tropical plants and coal deposits have been found in Antarctica. Why are these fossils evidence of climate change?
Now-a-days, there are no plants in Antarctica because it is every cold, but back then, it used to be warmer because it was closer to the Equator.
2)How does the Theory of Continental Drift provide an answer as to how tropical plants could grow on Antarctica?
In the Theory of Continental Drift, Antarctica was closer to the Equator, so there were plants growing, but as the continents drifted apart from each other, Antarctica moved away from the Equator, making it not-so-warm anymore
3) Evidence of glaciers has been found in the arid regions of Africa. Why would the existence of glaciers in this area be evidence of climate change?
During the "Permian" and all throughout "Jurassic", Africa was closer south than it it in present time, so the temperatures were colder than how it is today.
4) How could the Theory of Continental Drift provide and answer as to how glaciers could form in currently arid Africa?
The Theory of Continental Drift could provide an answer as to how glaciers could form in currently arid Africa because it used to be in the south, and the temperatures used to be colder.
