Introduction to Earth Science Chapter 1
Earth Science: the study of Earth and the universe around it What is Earth Science?
Geology Oceanography Meteorology Astronomy Also: Environmental Science Rocks Oceans Weather Space Human Impact Branches of Earth Science
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
Study of the Earth’s ocean’s Examples: waves, tides, ocean floor Oceans cover nearly 75% of the Earth’s surface Oceanographer Oceanography
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
Climate • The patterns of weather that occur over a long period of time
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
The effect of human interaction with the environment Natural resources, pollution, health of plant and animal species Environmental Science
Physical (3D) Mathematical Conceptual Volcanoes, Skyscraper (Graphical---Maps/Charts) Equations, numbers Classification of animal behaviors Models
AFDAC = Scientific Method • Ask a question • F orm a hypothesis • D esign an experiment • A nalyze the Results • C onclude
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)
Hypothesis = Educated Guess Theory = Possible explanation through tested hypothesis Law = Proven……… for now Hypothesis vs. Theory vs. Law
Peer Review • Experts in a given field examine the results and conclusions of an experiment before it can be accepted for publication
