Answer to Question 1

Answer: The slate headstone will be more legible/resistant. Marble is a softer rock and much more prone to dissolution from slightly acidic rain.

Answer to Question 2

Answer: Answers can include:
- The high amount of precipitation leaches most of the soluble materials
- Trees lock up most of the nutrients in their trunks
- Clearing of rainforests accelerates soil erosion
- Strong sunlight bakes the soils to a bricklike consistency
