Question

1. while studying the rocks and fossils in antarctica, geologists have found that it once had jungles. using the theory of continental drift, explain why/how this is even possible?

a. will the continents be in the same places in hundreds of millions of years from now? explain.

1. list and explain the 4 evidences which prove the theory of continental drift:

Explanation:

Question 8

Antarctica was once part of the supercontinent Pangaea, located near the equator where warm, wet conditions supported jungles. Over millions of years, continental drift moved Antarctica to its current polar position, but fossil/rock records preserve evidence of its ancient tropical environment.

Question 9

No, the continents will not be in the same places. Tectonic plates (driven by mantle convection) continue to move slowly (a few cm/year). Over hundreds of millions of years, this gradual motion will shift continents into new configurations (e.g., past supercontinents like Pangaea formed and broke apart due to this process).

Question 10

1. Fossil Correlation: Identical fossils (e.g., Mesosaurus, Glossopteris) are found on continents now separated by oceans, indicating they were once connected.
2. Rock Layer Matching: Similar sequences of rock layers (strata) and mountain ranges (e.g., Appalachians in N. America and Caledonians in Europe) align across continents, suggesting they were part of the same landmass.
3. Climate Evidence: Glacial deposits and coal beds (formed in warm swamps) are found in regions now too cold/hot for those environments, implying continents moved to new latitudes.
4. Puzzle-Like Fit: Continents (e.g., S. America and Africa) have complementary coastlines, fitting together like pieces of a puzzle—evidence they were once joined.

Answer:

1. Antarctica was part of Pangaea near the equator (supporting jungles) and drifted to the poles over time.
2. No; tectonic plates continue moving, shifting continents over millions of years.
3. 1. Fossil correlation (identical fossils across separated continents); 2. Rock layer/mountain alignment; 3. Climate evidence (glacial/coal deposits in mismatched regions); 4. Complementary continental coastlines.
