3. Exemplos de Flashcards de Alto Rendimento (Earth Science )

Nível	Frente (Pergunta / Termo)	Verso (Resposta / Explicação)
basic	What are the four primary compositional layers of Earth from the surface to the center?	1. Crust: Thin outermost silicate rock layer (continental: 30–70 km, granitic/felsic; oceanic: 5–10 km, basaltic/mafic). 2. Mantle: Thickest layer (~2,900 km deep), composed of dense silicate peridotite rock rich in iron and magnesium. 3. Outer Core: Liquid layer (~2,900–5,150 km) composed of molten iron-nickel alloy with light elements (S, O, Si). 4. Inner Core: Solid central sphere (~5,150–6,371 km radius) composed of crystallized iron-nickel alloy.
basic	What are the five mechanical (rheological) layers of Earth based on physical state and behavior?	1. Lithosphere: Rigid, brittle outermost mechanical layer comprising the crust and uppermost solid mantle (~100–150 km thick). 2. Asthenosphere: Ductile, highly viscous, partially molten (1–2%) plastic upper mantle allowing tectonic plate movement. 3. Mesosphere (Lower Mantle): Rigid, highly compressed solid rock extending to ~2,900 km depth. 4. Outer Core: Liquid convective metallic layer. 5. Inner Core: Solid metallic sphere under extreme lithostatic pressure.
intermediate	What are the primary gases comprising Earth's clean, dry atmosphere and their approximate volume percentages?	• Nitrogen (N2): 78.084% • Oxygen (O2): 20.946% • Argon (Ar): 0.934% • Carbon dioxide (CO2): ~0.042% (~420+ ppm and rising) • Trace gases: Neon, Helium, Methane (CH4), Krypton, Hydrogen, Xenon, Ozone (O3). (Note: Water vapor H2O is highly variable, ranging from 0.01% in polar regions to ~4% in tropical surface air).
intermediate	What are the four primary vertical layers of Earth's atmosphere defined by their thermal lapse rates?	1. Troposphere (surface to ~8–15 km): Temperature decreases with height (-6.5 °C/km); contains ~80% of mass and all weather. 2. Stratosphere (~15 to 50 km): Temperature increases with height (thermal inversion) due to ozone UV absorption. 3. Mesosphere (50 to 85 km): Temperature decreases with height to the coldest point in the atmosphere ( -90 °C). 4. Thermosphere (~85 to 600 km): Temperature increases dramatically (>1,000 °C) due to solar X-ray and EUV absorption by sparse gas molecules.
advanced	What is the mathematical equation for radiometric dating and what key assumptions underpin its validity?	D = D0 + P · (e^(λ · t) - 1) • D = Present quantity of stable daughter isotope • D0 = Initial quantity of daughter isotope incorporated at crystallization • P = Present quantity of radioactive parent isotope • λ = Radioactive decay constant (λ = ln(2) / t_1/2) • t = Age of the sample Assumptions: 1) System has remained strictly closed to parent/daughter loss or gain; 2) Initial daughter D0 is known or accounted for; 3) Decay constant λ has remained constant through geologic time.
advanced	What is the Isochron Dating method and how does it eliminate uncertainty regarding initial daughter isotope concentrations (D0)?	Isochron dating analyzes multiple cogenetic mineral phases with identical initial isotopic ratios but differing parent/stable ratios. Dividing the decay equation by a non-radiogenic stable isotope (Ds): (D / Ds) = (D0 / Ds) + (P / Ds) · (e^(λt) - 1) Plotting (D/Ds) versus (P/Ds) yields a straight line (isochron): • Y-intercept = Initial isotopic ratio (D0 / Ds) • Slope (m) = e^(λt) - 1 ==> t = (1/λ) · ln(m + 1) If the system was open or perturbed, data points will not form a collinear isochron, immediately revealing disturbance.
