P2.1 Branches of Earth Science

  1. 1. Branches of Earth Science Imagine that you are an earth scientist and can travel wherever you want to on earth. • Name and describe the aspects or features of earth you would like to study. • Where you would go and what you would do?
  2. 2. Objectives  Describe the four major branches of Earth science.  Identify four examples of Earth science that are linked to other areas of science.
  3. 3. Four Major Branches of Earth Science  Geology  Oceanography  Meteorology  Astronomy
  4. 4. Geology  The study of the origin, history, and structure of the Earth and the processes that shape the Earth.  Most geologists specialize in a particular aspect of the Earth.  Volcanologist  Seismologist  Paleontologist
  5. 5. Oceanography  Scientific study of the sea  Physical oceanographers  Biological oceanographers  Geological oceanographers  Chemical oceanographers  Oceanographers use miniature research submarines to travel far below the surface of the oceans
  6. 6. Meteorology  Scientific study of the Earth’s atmosphere, especially in relation to weather and climate.  Meteorologists warn people about severe weather such as hurricanes and tornadoes  Some meteorologists chase tornadoes and fly through hurricanes to study how they behave
  7. 7. Warmup  Without looking back try to name the 3 branches of Earth Science we talked about yesterday and list something specific that they study.  For example…  Biology: frogs  Chemistry: hydrogen atoms
  8. 8. Astronomy  Study of the universe  Astronomers use optical telescopes to see distant objects  Radio telescopes use radio waves to study objects that are too far away to be seen or that do not give off light
  9. 9. Astronomy  Astronomers spend much of their time studying stars.  Astronomers estimate that there are over 100 billion stars in the universe.  The star that has been studied the most is the one that is closest to Earth––the sun!
  10. 10. Special Branches of Earth Science  Other branches of Earth Science rely heavily on other areas of science  Environmental Science - Study of how humans interact with the environment  These scientists use geology, life science, chemistry, and physics.
  11. 11. Ecology  Study of communities of organisms and their nonliving environment  Ecologists work in fields such as wildlife management, agriculture, forestry, and conservation.
  12. 12. Geochemistry  Study of the chemistry of rocks, minerals, and soil  Geochemists judge the economic value of materials from the earth, determine what the environment was like when rocks formed, and study the distribution of chemicals.
  13. 13. Cartography  People who make maps of the surface features of the Earth  Cities are often located by geographic features, such as rivers, that are used for transportation.
