Echo sounding

Explanation:

Harry Hess discovered the Mid-Atlantic spreading ridge by using echo sounding techniques.

  • Hess was a professor of Geology at Princeton University.
  • After the second world war, series of equipment used were deployed for scientific use.
  • The echo sounding was one of such devices that was adopted in mapping the sea floor.
  • It works by sending an echo to the ocean floor and determining the height to the base by their reflection.
  • From his works, he observed and noticed the mid-oceanic ridge.
  • This led to the formulation of the theory of sea floor spreading.

¿En qué medida la guerra civil de 1829 representa una lucha ideológica?
rodikova [14]

To begin with, it is useful for armed organisations in socialising soldiers with disparate objectives into a cohesive group, reducing principal-agent issues, and prioritising competing aims.

Some individuals of terrorist organizations act on moral convictions in ways that are not reducible to utilitarian reasoning, while others limit their strategic options for altruistic purposes, which are frequently normative considerations dictated by their ideology.
