What is a chemical transport model (CTM), and what three physical processes does it couple within each grid cell?1 / 8

A CTM is a numerical model that simulates how air pollutant concentrations evolve in space and time by solving the atmospheric species continuity equation on a 3D grid. It couples: (1) advection/transport by resolved winds, (2) turbulent mixing (vertical diffusion, often within a boundary-layer scheme), and (3) chemical transformation (gas-phase and sometimes aerosol reactions) — each grid cell's concentration changes from all three simultaneously.

What is the symbiotic relationship at the heart of a healthy coral, and what does it provide?1 / 9

Coral polyps host zooxanthellae — photosynthetic algae living in their tissue. The algae photosynthesise and supply the coral with up to about 90% of its energy, while also giving the coral its vivid colour; in return, the coral provides shelter and compounds the algae need.

Why is riding a bike considered a very clean way to travel?1 / 8

A bike runs on your own leg power, so it produces no exhaust and burns no fuel at all.

What does exponential population growth look like, and when does it happen?1 / 9

A J-shaped curve where population size accelerates without limit — it happens when resources are effectively unlimited, so the growth rate stays constant regardless of how large the population gets.

What is a trophic level?1 / 9

A feeding position in a food chain — producers (level 1), primary consumers (level 2), secondary consumers (level 3), tertiary consumers (level 4), and so on — grouped by how many energy transfers separate an organism from the Sun.

Define capacity factor and write its formula.1 / 8

Capacity factor is the ratio of a generator's actual output over a period to what it would have produced running at full rated capacity the entire time. It captures intermittency and downtime: utility-scale solar PV typically runs ~20-25% CF, onshore wind ~35-45%, and nuclear ~90%+, reflecting how consistently each source can actually generate relative to its nameplate rating.
