Question

1. Antarctica is a frozen land, so cold and icy that no trees can grow there. Yet scientists have discovered fossils (remains preserved in rock) of ancient trees in Antarctica. What do you think this means

Answer 1

Answer:

This helps in understanding that Antarctica was once located in the tropical region, where a large number of trees were present, which were died and buried under the soil and rocks, and as the tectonic plates are continuously moving from one place to another, so Antarctica has now reached the south pole of the earth.

Answer 2

Answer:

Antarctica is found to be comprised of fossilized trees in its rocks. These trees were deposited long time back in the geological time scale. They are often found to be comprised of coal beds. This helps in understanding that the Antarctica was once located in the tropical region, where large number of trees were present, which were died and buried under the soil and rocks, and as the tectonic plates are continuously moving from one place to another, so the Antarctica has now reached the south pole of earth.

The presence of this fossilized trees gives an idea of how plates move from one location to another around the globe.
