The strength of the underlying geology, steepness of hillsides and faults in the Earth's crust which can potentially cause earthquakes are the geologic considerations during the identification of physically safe places for human habitation.
Geology basically deals with the study of the Earth and it finds a vital application in understanding the physical features of an area before it is inhabited by humans.
Human habitation on steep hillsides can be risky due to potential landslides and soil erosion which may occur due to rainfall or by rivers. It is also important to judge the strength of the underlying geology to ensure stability to the structures and buildings made to support habitation. The faults in the Earth's crust and the movement of the tectonic plates are responsible for causing Earthquakes. Seismic activity can lead to swaying of the structures and result in their instability which happens to risk human lives.

Biotic factors are the living components of an ecosystem. They are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.
Answer:
abiogenesis
Explanation:
Abiogenesis is the idea that supports the thought that the emergence of life is associated with the non-living things. It is believed that initially, the structure of the formation of life was simple. With further process, it turned to be complex. According to this hypothesis, the non-living matter of the Earth gave birth to the living matter.
In the given excerpt, the experiment performed by the evolutionists by using chemicals is an example of abiogenesis.
