Question

1. the factor that has the greatest effect on soil formation is

climate
parent material
time
slope orientation

Explanation:

In soil formation, climate is the most influential factor. It affects processes like weathering (rate and type), vegetation growth (which impacts organic matter input), and the movement of water and nutrients, all of which are fundamental to soil development. Parent material, time, and slope orientation also play roles but are less dominant than climate.
