Answer 1

In cool, dry climates, it may take centuries for the formation of a topsoil horizon capable of supporting substantial plant life or crops.

Step-by-step explanation:

In an area with a cool, dry climate, it may take centuries for the formation of a topsoil horizon capable of supporting substantial plant life or crops. The process of soil formation is a slow one and depends on various factors such as climate, organisms, relief, parent material, and time. In cool, dry climates, the slow decomposition of organic matter and the limited availability of water can cause the development of topsoil to take a long time.
