1 Earth science The study of how the earth changes over time Includes: GEOLOGY OCEANOGRAPHY METEOROLOGY ASTRONOMY
2 GEOLOGY “Study of the earth” Physical Geology: Processes that shape the planet (Plate Tectonics)Below the surface: earthquakes, mountains, volcanoesAt the surface: creation of landforms due to wind and erosionHistorical GeologyTimeline of changes on the earth
3 OCEANOGRAPHY Integrates Chemistry, Biology, Physics and Geology Study of:Composition and movement of seawaterCoastal processesSeafloor topographyMarine life
4 METEOROLOGYStudy of atmosphere and processes that produce weather and climateExamines the effects of the Earth’s motions and energy form the sun cause the atmosphere to produce weatherStudy of climates and patterns
5 Astronomy Study of the universe Study of Earth’s position in space and its relation to other bodiesSolar system/planetsMoon phasesStars & constellationsSpace exploration
6 FORMATION OF EARTHNEBULAR HYPOTHESIS: Bodies of the Solar System evolved from the solar nebula…an enormous rotating cloud made mostly of hydrogen and helium
7 ADD TO YOUR NOTES: Use p. 4Use the diagram of the Nebular Hypothesis Model to summarize the 5 key stages of the formation of the Solar System:A. Our solar system started as an enormous cloud (nebula) of gases and dust, mostly hydrogen and heliumB. The solar nebula began to rotate and collapse at the center, where heat was generated forming the sunC. As the nebula cooled, rocky and metallic materials formed tiny solid particlesD. These particles repeatedly collided and formed asteroid-sized bodiesE. These asteroids eventually combined to form the inner planets Lighter gases combined further away to form the outer planets.
