Vegetation influences climate primarily through ___________ Soil processing Wind circulation Atmospheric pressure Carbon and water cycles 4. Cyclones primarily form due to ___________ Warm ocean energy Wind circulation only Rainfall processes Cooling of ocean waters 5. Snow cover influences climate primarily through ___________ Atmospheric pressure Wind circulation Rainfall processes Albedo effect 6. Climate tipping points are best characterized by __________ Seasonal variability in threshold Reversibility beyond threshold Irreversibility once a critical threshold is crossed Gradual change in threshold 7. The characteristic that distinguishes tipping points from linear climate responses is ____________ Gradual change Nonlinearity and abrupt transition Predictability Proportionality 8. Which statement best explains why methane is both potent and short-lived? Strong radiative forcing but rapid atmospheric removal No chemical reactivity High reactivity but weak radiative forcing Low reactivity and low emissions 9.
