Answer to Question 1

As Mercury was molten, the dense iron and nickel sank to the core. But smaller Mercury cooled much faster than larger Earth and Venus, so as its core cooled, it also contracted as it solidified. The crust above wrinkled and formed the scarps due to this shrinkage.

Answer to Question 2

Sensible: By looking to a distance of 8 billion light-years, we can see objects as they looked 8 billion years ago.
