If you were a petroleum geologist searching for oil deposits (derived from ancient biomass), why would you want to know the positioning of these landmasses hundreds of millions of years ago? What climate region would you look for?
What will be an ideal response?
Petroleum deposits are generally associated with ancient plant communities. Knowing that equatorial latitudes are rich in photosynthetic communities fixing sunlight, it is important to find where landmasses were to identify where these deposits occurred. As the continents migrated after the breakup of Pangaea they carried these deposits with them and that is where the oil will be found today.
