Quiz5 questions

Why does ignoring autocorrelation when significance-testing a climate trend tend to overstate confidence?

AAutocorrelation always increases the true trend magnitudeBStandard tests assume independent observations; correlated data carry fewer truly independent data points than the raw sample size suggests, so uncorrected standard errors are too smallCAutocorrelated data cannot be plottedDIt has no effect — significance tests are unaffected by correlation structure

What are the three types of rock?1 / 6

Igneous rock forms when melted rock (magma) cools and hardens. Sedimentary rock forms from layers of sand, mud, or shell pressed together over time. Metamorphic rock is any rock that has been changed by heat or pressure deep underground.

Write the linearized global energy-balance equation defining the climate feedback parameter λ.1 / 8

ΔN is the top-of-atmosphere radiative imbalance, ΔF the applied forcing, ΔT the global mean surface temperature response, and λ (W/m²/K) the net climate feedback parameter. At equilibrium ΔN = 0, so ΔT_eq = ΔF/λ.

What is the urban heat island (UHI) effect?1 / 9

The tendency of cities to be measurably warmer than their surrounding rural areas, driven by how urban surfaces and structures absorb, retain, and generate heat differently than natural land cover.
