Study Notes

Notable Earth Scientists and Their Contributions

Marie Tharp
- Created the first scientific map of the ocean floor, revealing features like mid-ocean ridges.
Alfred Wegener
- Developed the continental drift theory; proposed that continents were once joined as Pangea.
- His work laid the groundwork for the modern understanding of plate tectonics.
Shen Kuo
- Introduced the concept of climate change and invented the early magnetic compass.
- Made significant astronomic observations and explained phenomena such as rainbows.
Inge Lehmann
- Proposed that the Earth's inner core is solid and outlined the multi-layer structure of Earth.
Charles and Mary Lyell
- Advocated for uniformitarianism, suggesting that current geological processes are the same as those in the past.
- Contributed extensively to stratigraphy and emphasized the Earth's ancient age.
Galileo Galilei
- Astronomer known for discovering Jupiter's four largest moons and enhancing telescope technology.
- Challenged the geocentric model, supporting heliocentrism.
Harry Hess
- Established that the ocean floor is dynamic and is a foundational figure in plate tectonic theory.
Edwin Hubble
- Contributed to the discovery of dark energy, which drives the expansion of the universe.
- Investigated the structure of the cosmos and what lies beyond it.
James Hutton
- Known as the founder of modern geology; influential in developing the concept of unifomitarianism.
Louis Agassiz
- A prominent glaciologist who identified evidence for the Earth having undergone an ice age, shaped by glaciers.
Nicolaus Copernicus
- Proposed that Earth is not the center of the universe, leading to revolutionary changes in astronomy.
Jacques Cousteau
- Invented the aqua-lung, significantly advancing underwater exploration and marine conservation efforts.
Tycho Brahe
- Improved celestial observation instruments, producing accurate measurements of astronomical objects.
Charles Darwin
- Developed the theory of evolution through natural selection, influenced by his observations of wildlife and fossils.
John Wesley Powell
- Led expeditions through the Grand Canyon and contributed to geological mapping of the region.
Charles Richter
- Created the Richter scale, a standardized method for measuring earthquake magnitudes.
Nicolas Steno
- Pioneered stratigraphy and challenged misconceptions about fossils, asserting their biological origins.
