Study Notes
Earth Science Branches and Disciplines
- Earth science encompasses the study of Earth and its neighboring planets, encompassing historical events and formation processes.
- Key branches include:
- Geology: The study of Earth, further divided into:
- Physical geology: Focuses on Earth's structure, form, and components.
- Historical geology: Studies the formation of Earth and life over time.
- Seismology: Studies earthquakes.
- Volcanology: Studies volcanoes.
- Meteorology: Analysis, prediction, and forecasting of weather patterns, high-sky conditions, and climate.
- Astronomy: Study of the universe.
- Oceanography: Study of the oceans, including tides, waves, processes, and climate change effects.
- Geology: The study of Earth, further divided into:
Scientific Vocabulary and Learning Styles
- Scientific terms are often derived from Greek and Latin roots, like "geo" (Earth) and "-ology" (study of).
- Word parts (prefixes, roots, suffixes) are crucial for understanding scientific terminology.
- Learning styles include auditory (hearing), visual (sight), hands-on (practice), and holistic or analytic approaches.
Scientific Method
-
A systematic process for answering scientific questions.
-
Steps may vary by experiment and discipline.
-
Steps generally include: - Forming a question. - Conducting background research. - Developing a hypothesis. - Designing and conducting an experiment. - Analyzing data. - Reaching a conclusion.
- Important concepts include:
- Independent variable: The factor being tested.
- Dependent variable: The factor being measured.
- Empirical data: Data obtained through observation and experience.
- Biases: Potential prejudices impacting experimental results.
- Peer review: Evaluating scientific data by other scientists.
- Scientific theory: Hypothesis supported by extensive research.
- Important concepts include:
Experimental Design
- The process of planning and conducting a scientific experiment.
- Key steps include:
- Defining variables.
- Formulating hypotheses.
- Designing the experimental process.
- Assigning subjects.
- Measuring the dependent variable.
International System of Units (SI)
- The standard system of measurement, based on a decimal system (factor of 10).
- Units for key physical quantities include:
- Length (meter)
- Mass (kilogram)
- Volume (m³)
- Density (kg/m³)
- Temperature (kelvin)
Scientific Data Presentation
- Various methods for displaying data, including graphs and charts:
- Line graphs: For trends over time, numerical data.
- Bar charts: Compare data among different groups, often numerical and categorical.
- Pie charts: For percentages, numerical and categorical data.
- Flow charts: Show relationships and processes.
- Independent Variable (x-axis), Dependent Variable (y-axis)
Geologic Time Scale
- Earth's history divided into time units (eons, eras, periods, epochs).
- Precambrian eon: Early eons, before multicellular life.
- Phanerozoic eon: Post-precambrian; includes multicellular life.
- Layers of rock (strata) and fossils used to understand Earth's history.
- Stratigraphy: The study of rock layers.
- Relative age dating: Determining age based on position in rock layers.
- Radiometric dating: Determining age based on radioactive decay.
Catastrophism and Uniformitarianism
- Catastrophism: Earth's features shaped by sudden, large-scale events.
- Uniformitarianism (Modern view): Earth's features formed by gradual processes, similar to those observed today.
- Modern view combines aspects of both theories.
Radiometric Dating
- Determines the age of materials based on the decay rate of radioactive isotopes.
- Radioactive decay: Process where unstable atoms lose energy through radiation.
- Parent nuclide: The initial unstable atom.
- Daughter nuclide: The stable atom created through decay.
- Types of decay include:
- alpha decay
- beta decay
- gamma decay
- Half-life: The time it takes for half a substance to decay.
- Common methods used include:
- Uranium-lead dating
- Potassium-argon dating -Rubidium-strontium dating
- Radiocarbon dating
Relative Dating
- Determining the age of a geologic feature relative to other features.
- Key principles include: - Uniformitarianism - Original Horizontality - Lateral Continuity - Superposition - Cross-cutting Relationships - Inclusions - Baked Contacts - Unconformities (disconformity, nonconformity, angular unconformity)
- Often used as a first step, followed by absolute dating for more precise ages.
