The study of how the earth changes over time
Includes:
GEOLOGY OCEANOGRAPHY METEOROLOGY ASTRONOMY
EARTH SCIENCE
GEOLOGY
• “Study of the earth”
• Physical Geology:
• Processes that shape the planet (Plate Tectonics)
• Below the surface: earthquakes, mountains, volcanoes
• At the surface: creation of landforms due to wind and erosion
• Historical Geology
• Timeline of changes on the earth
OCEANOGRAPHY
• Integrates Chemistry, Biology, Physics and Geology
• Study of:
• Composition and movement of seawater
• Coastal processes
• Seafloor topography
• Marine life
METEOROLOGY
• Study of atmosphere and processes that produce weather and climate
• Examines the effects of the Earth’s motions and energy form the sun cause the atmosphere to produce weather
• Study of climates and patterns
ASTRONOMY
• Study of the universe
• Study of Earth’s position in space and its relation to other bodies
• Solar system/planets
• Moon phases
• Stars & constellations
• Space exploration
FORMATION OF EARTH
NEBULAR HYPOTHESIS: Bodies of the Solar
System evolved from the solar nebula…an
enormous rotating cloud made mostly of hydrogen
and helium
ADD TO YOUR NOTES: USE P. 4
• Use 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 helium
• B. The solar nebula began to rotate and collapse at the center, where heat was generated forming the sun
• C. As the nebula cooled, rocky and metallic materials formed tiny solid particles
• D. These particles repeatedly collided and formed asteroid-sized bodies
• E. These asteroids eventually combined to form the inner planets. Lighter gases combined further away to form the outer planets.
