  1. geomorphology
    the science that studies the formation of rocks and land forms
    While his paper of 1785 suggested an entirely new theory of geomorphology (the study of landforms and their development), it was the 19th century scholar Sir Charles Lyell whose Principles of Geology (1830) popularized the concept of uniformitarianism.
  2. tectonic movement
    movement resulting from or causing deformation of the earth's crust
    The earth is estimated to be approximately 4.55 billion years old and the planet has certainly had enough time for slow, continuous processes to mold and shape the earth (including the tectonic movement of the continents around the globe).
  3. erode
    remove soil or rock
    He realized that, if given enough time, a stream could carve a valley, ice could erode rock, sediment could accumulate and form new landforms.
  4. geology
    science of the history of the earth as recorded in rocks
    In the mid-seventeenth century, biblical scholar and Archbishop James Ussher determined that the earth had been created in the year 4004 BC. Just over a century later James Hutton, known as the father of geology, suggested that the earth was much older and that processes occurring in the present were the same processes that had operated in the past, and would be the processes that operate in the future.
  5. sediment
    matter that has been deposited by some natural process
    He realized that, if given enough time, a stream could carve a valley, ice could erode rock, sediment could accumulate and form new landforms.
  6. volcano
    a fissure in the earth's crust through which gases erupt
    Today, we hold uniformitarianism to be true and know that great disasters such as earthquakes, asteroids, volcanoes, and floods are part of the regular cycle of the earth.
  7. earthquake
    vibration from underground movement along a fault plane
    Today, we hold uniformitarianism to be true and know that great disasters such as earthquakes, asteroids, volcanoes, and floods are part of the regular cycle of the earth.
