Study Notes
Tsunamis
- Primary Cause: Large earthquakes beneath the ocean floor.
Earth's Spheres
- Geosphere: All solid lands in the crust, considered abiotic.
- Hydrosphere: Consists of all the water on Earth, including rivers, streams, and oceans.
- Biosphere: Contains all living organisms on Earth.
Earth's Layers
- Crust: Brittle layer composed of rocks, metals, and minerals.
- Mantle: Composed primarily of silicate minerals.
- Outer Core: Liquid iron at extremely high temperatures.
- Inner Core: Solid iron and nickel.
Earthquakes and Seismic Activity
- Cause: Movement of tectonic plates along fault lines.
Earth's Composition
- Crust: Mostly composed of oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
- Atmosphere: Composed primarily of nitrogen, oxygen, argon, and carbon dioxide.
Earth's Magnetic Field
- Source: The movement of molten iron in the Earth's outer core.
Seismic Waves
- P Waves: Are compressional waves that can travel through both solids and liquids.
Plate Tectonics
- Theory: Explains the movement of Earth's tectonic plates.
- Driving Force: Convection currents in the mantle.
- Evidence: Geological features like seafloor spreading, magnetic striping, and earthquake patterns.
Continental Drift
- Theory: Proposed by Alfred Wegener.
- Evidence: Matching coastlines, fossil distributions, and geological formations across continents.
Chemical Reactions
- Combination Reactions: Two or more reactants combine to form a single product.
- Double-Replacement Reactions: Two ionic compounds swap ions to form two new compounds.
Atoms and Elements
- Atomic Number: Represents the number of protons in an atom's nucleus.
- Mass Number: Determined by the sum of protons and neutrons in an atom's nucleus.
States of Matter
- Solid: Low energy, high density, definite volume, and definite shape.
- Liquid: Moderate energy, moderate density, definite volume, and indefinite shape.
- Gas: High energy, low density, indefinite volume, and indefinite shape.
- Plasma: Ionized gas with unique properties.
Phase Changes
- Condensation: Gas or vapor to liquid.
- Evaporation: Liquid to vapor.
- Sublimation: Solid to gas.
- Deposition: Gas to solid.
- Melting: Solid to liquid.
- Freezing: Liquid to solid.
Key Concepts
- Critical Point: The point on a phase diagram where a substance can exist in all three states simultaneously.
- Phase Change: Transition between the states of matter.
- Ionization: The process of forming ions by gaining or losing electrons.
Earth's Interconnectedness
- Biosphere and Other Spheres: Rooted plants connect the biosphere to the geosphere, hydrosphere, and atmosphere for survival.
Volcanoes and Earth's Interior
- Volcanoes: Offer a glimpse of the Earth's interior through molten rock (magma) eruptions.
Key Laws of Chemistry
- Law of Conservation of Mass: Matter is neither created nor destroyed in a chemical reaction.
- Law of Definite Proportions: A given chemical compound always contains the same elements in the same proportion by mass.
