  1. 2. French geophysicist and geodesist whose expedition over the Andes enabled him to become the person to measure the horizontal gravitational pull of mountains.
  2. 3. Scottish geologist, chemist and naturalist who established one of the fundamental principles of geology – uniformitarianism.
  3. 5. Danish geologist who proposed the revolutionary idea that fossils are the remains of ancient living organisms and that many rocks are the result of sedimentation, containing a chronological history of geologic events.
  4. 7. Scottish geologist largely responsible for the general acceptance of the view that all features of the Earth’s surface are produced by physical, chemical, and biological processes through long periods of geological time.
  5. 11. French naturalist whose works laid the foundation of vertebrate palaeontology. He established extinction as a fact and later became the most influential proponent of catastrophism in geology.
  6. 13. German geophysicist who first proposed the controversial yet radical theory of continental drift
  7. 14. American seismologist and physicist who developed a scale for measuring earthquake magnitude.

  1. 1. Generally regarded as one of the greatest mathematicians of all time for his contributions to number theory, geometry, probability theory, geodesy, planetary astronomy, the theory of functions, and potential theory, including electromagnetism.
  2. 4. Canadian geologist whose contributions to the theory of plate tectonics introduced the idea of hotspots and the recognition of transform boundaries, and who later postulated a model for the formation and breakup of continents.
  3. 6. American geologist and pioneer in the field of planetary science who became the first and so far only person ever to receive a lunar burial.
  4. 8. The German physicist whose name is synonymous with the method of seismic migration.
  5. 9. Hungarian mathematician and physicist that invented the torsion pendulum and for which the unit of gravity gradient is named after.
  6. 10. A Swiss peasant and mountaineer whose observations started the science of glaciology.
  7. 12. Geophysicist whos equations relate the amplitudes of P-waves and South-waves at each side of an interface, between two arbitrary elastic media, as a function of the angle of incidence and are largely used in reflection seismology for determining structure and properties of the subsurface.
