Geological considerations to identifying physically safe places for human habitation are:
- The strength of underlying geology
- Faults in earths crust that can potentially cause earthquakes
- The steepness of hillsides
What is geology?
- It is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time.
- Modern geology significantly overlaps all other Earth sciences, including hydrology and the atmospheric sciences, and so is treated as one major aspect of integrated Earth system science and planetary science.
- Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure.
- It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks.
- Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates.

I don’t want to make you get it incorrect.
The primary cost component for American scheduled airlines is fuel, which accounts for the majority of operational expenses.
<h3>
What are fixed and variable costs for an airline?</h3>
In contrast to variable costs, which change over time, fixed expenses remain the same. Variable costs, which include things like fuel, oil, maintenance, landing fees, etc., on the other hand, are subject to change. The fixed costs do not change regardless of how much time you spend flying your aircraft.
<h3>
What are aircraft direct operating costs?</h3>
The term "direct operating cost" (DOC) refers to expenses that are directly connected to running a flight, such as flight attendant pay, aircraft fuel and oil, lease rental or depreciation, maintenance costs, insurance premiums, ground handling, navigational fees, landing and parking fees, and in-flight catering services.
