Based on what you know about petrified fossils, the following statements apply:
1. **The area was once a forest.** - True. Petrified wood comes from trees that were once alive, indicating that the area was likely a forest in the past.
2. **The area was uplifted.** - True. Many areas where petrified wood is found have undergone geological uplift due to tectonic forces, exposing the fossils that were buried.
3. **The area was void of organic material.** - False. The presence of petrified wood indicates that there was once organic material, specifically trees, in the area.
4. **The area was probably covered by water.** - True. Many petrified fossils form in environments where the wood is submerged in water, allowing for the mineralization process to occur.
5. **The area was covered by volcanic material.** - This can be context-dependent, but it is not universally true. Some petrified wood is found in areas with volcanic activity, as volcanic ash can help facilitate the fossilization process, but this is not a requirement for petrification.
So, the true statements are:
- The area was once a forest.
- The area was uplifted.
- The area was probably covered by water.
