Earth Science
- Earth and Space
- Ideas
- Old
- Geocentric
- Earth is center
- New
- Heliocentric
- Sun is center
- Basic Physics
- Luminosity
- Definition
- Brightness
- Concept
- Brighter stars - closer to Earth
- Dimmer stars - farther from Earth
- Doppler Effect
- Definition
- Change in frequency of sound waves and light
waves
- Concept
- Sound waves
- High frequency (short wavelength) - near
the Earth
- Low frequency (long wavelength) - far from
Earth
- Light waves
- ROYGBIV concept
- Red stars - far from Earth
- Violet stars - near the Earth
- The Big Bang Theory
- Concept
- Stars DIE when hydrogen is USED UP
- Stars FORM when hydrogen FUSE TOGETHER
- 90% of the composition of human body: C, H, O
- Sun
- Has dark spots (cooler) due to magnetic fields
- Equatorial and Polar Regions
- Earth deflects solar wind from Sun
- Solar wind + Earth's magnetic field = Aurora
- Sunspot cycle (solar maximum/minimum): 11
years
- Solar System
- Planets
- Kinds
- Terrestrial
- Definition
- Mostly rocks
- Examples
- Mercury
- Venus
- Earth
- Mars
- Jovian
- Definition
- Mostly gases
- Has thick atmosphere
- Examples
- Jupiter
- Saturn
- Neptune
- Uranus
- Earth
- Composition
- Crust
- Contains lighter elements
- Mantle
- Contains rocks
- Core
- Has solid inner and melted outer
- Contains iron and nickel
- Spheres
- Division
- Asthenosphere
- It is plastic and the upper mantle
- Lithosphere
- It is the crust and upper mantle
- Concept
- More depth = Temperature increases
- Younger biosphere = Less oxygen
- Characteristics
- Has liquid water
- Has gravity
- Has a protective atmosphere
- Has life-sustaining gases
- Has a strong magnetic field
- Plate Tectonics
- Theories
- Contracting Earth (Raisin)
- Concept
- Cooling and contracting of planet
- Contraction of surface (mountains = wrinkles)
- Collapse of surface; Formation of ocean
basins
- Continents and oceans are fixed in place
- Creates vertical crust movements
- It is the 20th century paradigm
- Continental Drift (Wegener's)
- Concept
- 250M years ago: Pangea
- Continents drifted
- Observations
- Matching fossils
- Mountain belt (North America, Europe,
Greenland)
- Rocks
- Glacial deposits (ice sheet)
- Reasons why it is not accepted
- No explanation why it happened/how
continents moved
- Land bridges
- Evidence from the Seafloor
- Seafloor Topography
- Key features
- Oceanic ridge
- Submarine mountain range and source of
volcanic activity
- Often found toward center of oceans
- Occupies much of the seafloor in ocean basins
- Oceanic trench
- Narrow, deepest portion of ocean floor
- Continental shelf
- Narrow, shallow ocean surrounding continents
- Abyssal Plain
- Relatively level seafloor, often with volcanoes
- Age of the Seafloor
- Varies systematically
- Seafloor rocks are younger compared to most
continent rocks
- Heat flow
- Varies systematically
- Highest along oceanic ridges
- Lowest on continents and in oceans from ridges
- Volcanoes
- Most active are found near oceanic trenches
- Earthquakes
- Deeper earthquakes at longer trenches
- Volcanoes and Other Mountains
- Rocks and Minerals
- Earthquakes
- Weathering and Soil
- Landslides and Slope Failure
