Final answer:
Ground-based physical sense techniques include gravitational measurements, gamma-ray detections, and medical tests like praxis for task execution and gnosis for object identification, all relying on sensing environmental changes or testing human sensory feedback.
Step-by-step explanation:
Examples of ground-based physical sense techniques include gravitational measurements, gamma-ray detections, and sensory perception tests such as praxis and gnosis.
- Gravitational measurements can detect nearby geographical features like mountains by sensing variations in gravity due to changes in local geology.
- Gamma-ray detections are possible on Earth's surface using the atmosphere as a detector, where cascades of light and energy from accelerated charged particles are observed by ground-based observatories such as the VERITAS array in Arizona and the H.E.S.S. array in Namibia.
Finally, physical sense techniques applied in medicine, such as praxis and gnosis, involve carrying out tasks or identifying objects through sensory feedback, which are crucial for assessing a patient's sensory perception capabilities.
