Question

reconstructing a landscape
which statements about this area are true based on what you know about petrified fossils? check all that apply.
□ the area was once a forest.
□ the area was uplifted.
□ the area was void of organic material.
□ the area was probably covered by water.
□ the area was covered by volcanic material.

Explanation:

1. Petrified fossils form from organic plant material (like trees), so the area was once a forest.
2. The fossils are now exposed in a dry, elevated landscape, meaning the area was uplifted over geologic time.
3. Petrification requires sediment (often carried by water) to bury and preserve the organic material, so the area was likely covered by water at one point.
4. The area had abundant organic material (the source of the fossils), so the "void of organic material" statement is false. There is no evidence in the image or standard petrification processes to confirm volcanic material covered the area, so that statement is also false.

Answer:

• The area was once a forest.
• The area was uplifted.
• The area was probably covered by water.
