Answer to Question 1

Answer: The weathering was mechanical; - even though explosives were used, they did not change the chemical makeup of the rock. It was just broken into smaller pieces.

Answer to Question 2

Answer: When a soil is young, the character of the parent material strongly influences the characteristics of the soil. However, over time, other soil-formation factors, particularly climate, are going to become dominant.
