Environment differences between today and when the rocks formed

The new ELI today is 'Now and then – spotting the difference; how did the conditions differ between today and when the rock was formed?'

Between now (today) and then (when the rock was formed) how have these things changed?:
- temperature
- orientation
- humidity
- altitude
- visibility
- latitude
- pressure
- age
- life, invertebrates and vertebrates
This is a thought experiment, attempting to compare various aspects of the environment when the rock was formed, with conditions today.
