  1. Introduction to Earth Science Chapter 1

  2. Earth Science: the study of Earth and the universe around it What is Earth Science?

  3. Geology Oceanography Meteorology Astronomy Also: Environmental Science Rocks Oceans Weather Space Human Impact Branches of Earth Science

  4. The study of the origin, history, and structure of the Earth and its processes Examples: rock structure, fossils Geologist: a person who studies geology Geology

  5. Study of the Earth’s ocean’s Examples: waves, tides, ocean floor Oceans cover nearly 75% of the Earth’s surface Oceanographer Oceanography

  6. Study of the Earth’s atmosphere in relation to weather and climate Major Instruments used are: satellites and radar Observable factors of weather: temperature rainfall, wind speed Meteorologist Meteorology

  7. Climate • The patterns of weather that occur over a long period of time

  8. Study of universe beyond the Earth Modern advances that help study the sun, moon, planets and the universe are: telescopes, rovers, space probes Astronomers Astronomy

  9. The effect of human interaction with the environment Natural resources, pollution, health of plant and animal species Environmental Science

  10. Physical (3D) Mathematical Conceptual Volcanoes, Skyscraper (Graphical---Maps/Charts) Equations, numbers Classification of animal behaviors Models

  11. AFDAC = Scientific Method • Ask a question • F orm a hypothesis • D esign an experiment • A nalyze the Results • C onclude

  12. Theories are used to explain observations and predict what may happen Theory: explanation that ties together many related observations, facts, and tested hypotheses What happens when a theory and its models correctly predict the results of many experiments? Law: summary of many experimental results and observations, tells how things work Scientific Knowledge (Theories/Laws)

  13. Hypothesis = Educated Guess Theory = Possible explanation through tested hypothesis Law = Proven……… for now Hypothesis vs. Theory vs. Law

  14. Peer Review • Experts in a given field examine the results and conclusions of an experiment before it can be accepted for publication
