Study Notes
Lab Safety and Equipment
- Three safety rules:
- Wear safety goggles at all times
- Wear closed-toe shoes
- No food allowed
- Equipment for measuring:
- Mass: triple beam balance
- Volume: graduated cylinder
- Temperature: thermometer
Scientific Method
- Steps in the scientific method:
- Problem/purpose/question
- Research (internet/books)
- Hypothesis (educated guess)
- Experiment (test the hypothesis)
- Observations (what happens)
- Data analysis/results (observations)
- Conclusion (summary of the question)
Earth's Interior
- Geologists study the Earth's interior using seismic waves.
- Earth's four spheres:
- Geosphere (land)
- Hydrosphere (water)
- Atmosphere (air)
- Biosphere (living things)
- Earth's layers and details:
- Inner core: solid, hottest
- Outer core: iron, nickel
- Mantle: thickest layer, upper, central, and lower mantle layers.
Convection Currents in the Mantle
- Convection currents in the mantle are caused by temperature differences between the hot core and cooler upper mantle, resulting in the movement of dense and less dense material.
- Two results of convection currents:
- Hotter temperatures rise
- Cooler temperatures sink
Heat Transfer
- Three forms of heat transfer:
- Convection: Heat transfer through fluids (Example: hot air balloon).
- Conduction: Heat transfer through solids (Example: frying food).
- Radiation: Heat transfer through empty space (Example: grilling).
Continental Drift and Plate Tectonics
- Evidence for continental drift and plate tectonics is not fully explained in the provided text.
Earthquakes
- Earthquakes occur when energy builds up at faults due to tectonic plate movement. When rocks slip, the stored energy is released.
- Ways geologists learn about the Earth's interior: earthquakes and volcanoes.
- Types of plate boundaries and their characteristics
- Divergent: plates moving apart (Mid-Atlantic Ridge, Great Rift Valley)
- New crust formation, canyons, valleys, cracks, sea floor spreading
- Convergent: plates colliding (Himalayas, Andes Mountains)
- Mountains and Volcanoes if one plate slides under the other ( subduction)
- Transform: plates sliding past each other (San Andreas Fault)
- Earthquakes and Faults
- Divergent: plates moving apart (Mid-Atlantic Ridge, Great Rift Valley)
Seismic Waves
- Seismograph: instrument used to record seismic waves.
- Seismogram: Record of earthquake activity, shows p-waves, s-waves, and surface waves.
Types of Seismic Waves
- P-waves: Fastest, back and forth motion, travel through solids and liquids.
- S-waves: Slower, up and down/side to side motion, travel through solids only.
- Surface waves: After body waves, cause damage, travel along the Earth's surface (similar to ocean waves).
Measurement Scales for Earthquakes
- Richter Scale: Measures earthquake magnitude on a logarithmic scale (each decimal level is 10X higher), based on seismogram readings.
- Mercalli scale: measures the intensity of an earthquake based on the observed effects of the earthquake. (Roman numerals, based on observations, not as scientific.)
Volcanoes
- Main parts of a volcano (diagram) should be labeled.
- Types of volcanoes and their descriptions:
- Cinder Cone: Steep cone shape, bowl-shaped crater.
- Shield: Looks like a shield, lava spreads evenly.
- Composite: Curving sides, alternating layers of volcanic materials (ash, cinders, rock, etc), intense eruptions.
