ELS L1

• Field of study for Earth Scientist

  • Entire planet and all its physical characteristics
• Earth is the only planet in our solar system not named after a Greek or Roman deity
• Four Earth Sciences

  • Geology
  • Meteorology
  • Astronomy
  • Oceanography
• Astronomy

  Study of the universe
• Oceanography

  Study of Earth's oceans including composition, movement, organisms, processes, and their importance as resources
• Meteorology

  Science of the atmosphere determining Earth's weather and climate
• Earth is the third planet from the Sun and is the largest of the terrestrial planets
• Earth was formed approximately 4.54 billion years ago and is the only known planet to support life
• Climate changes over time in response to human actions is a topic of urgent worldwide concern
• Geologists' tasks

  • Search for fuels and minerals
  • Study natural hazards
  • Protect Earth's environment
• Oceanographers work to develop the ocean as a resource and protect it from human impact
• Earth Science

  The study of the Earth and its neighbors in space
• Geology

  Primary Earth science dealing with the composition of Earth materials, structures, processes, and how the planet has changed over time
• Meteorology is a very practical science as everyone is concerned about the weather
• Earth

  ertha
• Earth characteristics studied by Earth scientists

  • Motion of the atmosphere
  • Formation of rocks
  • Eruption of a volcano
• Importance of oceans

  • Food resources
  • Energy source
  • Influence on weather and climate change
• Astronomy

  The science of the universe
• Geology is the study of the Earth’s history, structure, and composition
• Oceanographers work

  To develop the ocean as a resource and protect it from human impact
• Knowledge of astronomy is essential in understanding the Earth: ocean's tidal system, asteroid impacts, source of energy (solar energy)
• Ways to use knowledge of astronomy

  1. Locate and develop energy and mineral resources

  2. Design methods to protect the planet by studying the impact of human activity on Earth's environment

  3. Plan communities that will not expose people to dangerous events like volcanic eruptions, earthquakes, and hurricanes
• Mineralogy is the study of minerals (chemistry, crystal structure, and physical properties) by which rocks are made
• Historical Geology is the study of the evolution of the Earth
• Sources for food and other commodities

  • Energy source
• Hydrology is the study of water distribution and behavior focusing on inland and underground water sources
• Performance Task #1: Make a poster that shows Sciences related to Earth Science. Put it on a short bond paper. (100 points)
• Paleontology is the study of fossil remains
• Rubric for the performance task: Originality – 10 points, Creativity – 30 points, Neatness – 20 points, Accordance/ Relevance to the topic – 40 points
• Geography is the study of the Earth’s surface (land, features, and inhabitants)
• Hydrography is the surveying and mapping of large bodies of water
• Geophysics is the study of the physical processes that occur in and around the Earth
• Volcanology is the study of volcanoes
• Geomorphology is the study of landforms (physical features of the surface of the earth)
• Oceans


  Have a major influence on the weather as changes in the oceans can drive or moderate climate change
• Astronomy is the study of the universe
• Sciences related to Earth Science

  • Geology
  • Historical Geology
  • Petrology
  • Mineralogy
  • Geophysics
  • Volcanology
  • Paleontology
  • Geography
  • Geomorphology
  • Hydrology
  • Hydrography
  • Ecology
• Petrology is the study of rocks (origin, small-scale structure, and composition)
• Ecology is the study of the relationships between living things and their environment
