1000 years
To determine how long it takes for soil to form from bedrock, we can consult scientific sources such as research papers or reputable websites. In this case, I found a source on the Seafriends website (http://www.seafriends.org.nz/enviro/soil/geosoil.htm#soil) that provides information on soil formation.
According to the source, it takes several centuries for soil to gradually form from bedrock. The process usually involves the weathering of rocks and the accumulation of organic matter over time. Based on the information provided in the source, the answer options of 1 year, 10 years, or even 100 years are not long enough for soil formation to occur.
The most suitable answer based on the information provided is option D, 1000 years. However, it's important to note that this estimate can vary depending on factors such as climate, vegetation, and parent rock type.
