The geologic features that help scientists to determine the relative ages of rocks by their positions include index fossils, intrusions, and cross-cutting relationships (Option d).
<h3>What does geological age mean?</h3>
The expression geological age refers to the relative age of a given rock and or fossil (i.e. a piece or trace of dead organism) in a geological time scale.
In conclusion, the geologic features that help scientists to determine the relative ages of rocks by their positions include index fossils, intrusions, and cross-cutting relationships (Option d).

Answer:
1st Step: Observation
2nd Step: Questioning
3rd Step: Data Collection
4th Step: Data analysis
5th Step: Communication
In the scientific method, the first step is always to make an observation. You can observe anything in your environment, or a phenomena, or behavior.
The next step would be to question. You form a question to find a possible explanation as to why what you had observed occurred. This is also when you make a hypothesis. An educated guess or a proposal that could explain the event.
After you make a hypothesis, you start an experiment where you will collect data. The data you collect would then be analyzed (4th step). From there you build your conclusion to determine whether your hypothesis holds true.
The last step would be communication. You will communicate the results of your method. This allows people to review your data and process, which may be supported or invalidated. Communication is critical in the scientific world because your results could be the basis for further investigation.
This decrease of pressure in the thoracic cavity relative to the environment makes the cavity pressure less than the atmospheric pressure. This pressure gradient between the atmosphere and the thoracic cavity allows air to rush into the lungs; inhalation occurs. The resulting increase in volume is largely attributed to an increase in alveolar space because the bronchioles and bronchi are stiff structures that do not change in size.
