Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to ( Decrease increase remain constant) which aided formation of ( chloroplast soil roots)

Answer 1

Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to increase, which aided the formation of soil.

As oxygen levels rose, chemical weathering processes, such as oxidation, became more prevalent, contributing to the breakdown of rocks and minerals and the formation of soil.
