The answer for "What is petrified wood made of?" would be minerals.
I don’t think there is an answer for that
The texture of sedimentary rocks, like the size of grains or chemical precipitates can show how the rock was formed. The fossils of sedimentary rocks can show when the rock was formed. The stratification and sorting of the particles can show were the rock was formed.
A conic map is the best bc it has very little distortion and straight latitude and longitude lines
