Smog, Acid Rain, Aqi — Smog Types
Grey coal smog vs brown photochemical.
Learning objectives
- Define smog types using accurate chemistry terms.
- Explain why smog types matters within smog, acid rain, aqi.
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.
Definition
Grey coal smog vs brown photochemical. PAN irritates eyes (named). Temperature inversion named as trapping pollution (weather idea). Acid rain: H2SO4 and HNO3 from SO2 and NO2 — damages buildings and lakes. This page separates the idea from the wider topic “SMOG, ACID RAIN, AQI” so it can be revised and assessed on its own.
Important terms
- SMOG TYPES
- Grey coal smog vs brown photochemical.
- SMOG, ACID RAIN, AQI
- Classical smog: smoke + fog + SO2 (old coal cities named).
Overview
Study this learning unit in three steps:
Key Idea
Grey coal smog vs brown photochemical. PAN irritates eyes (named). Temperature inversion named as trapping pollution (weather idea). Acid rain: H2SO4 and HNO3 from SO2 and NO2 — damages buildings and lakes.
Examples Coal + SO2 · Sun + NOx · Inversion named
Exam Application
Exam photochemical smog: sunlight + NOx + hydrocarbons ground ozone and PAN named prevention: fewer vehicle emissions (slogan)
Examples Coal + SO2 · Sun + NOx · Inversion named
WHAT — SMOG, ACID RAIN, AQI — SMOG TYPES
Grey coal smog vs brown photochemical. PAN irritates eyes (named). Temperature inversion named as trapping pollution (weather idea). Acid rain: H2SO4 and HNO3 from SO2 and NO2 — damages buildings and lakes. This page separates the idea from the wider topic “SMOG, ACID RAIN, AQI” so it can be revised and assessed on its own.
WHY — Why this topic matters
SMOG, ACID RAIN, AQI — SMOG TYPES is an independent FBISE learning unit because students must use its definitions, conditions, equations, or trends separately in explanations and calculations.
HOW — How it works
Grey coal smog vs brown photochemical. PAN irritates eyes (named). Temperature inversion named as trapping pollution (weather idea). Acid rain: H2SO4 and HNO3 from SO2 and NO2 — damages buildings and lakes. Examples: Coal + SO2; Sun + NOx; Inversion named. Exam use: Exam photochemical smog: sunlight + NOx + hydrocarbons ground ozone and PAN named prevention: fewer vehicle emissions (slogan)

Core idea
- Grey coal smog vs brown photochemical. PAN irritates eyes (named). Temperature inversion named as trapping pollution (weather idea). Acid rain: H2SO4 and HNO3 from SO2 and NO2 — damages buildings and lakes. This page separates the idea from the wider topic “SMOG, ACID RAIN, AQI” so it can be revised and assessed on its own.
WHAT
- Grey coal smog vs brown photochemical.

Common misconception
- Do not treat smog types as the same as every other part of smog, acid rain, aqi; define this unit and use its own evidence, steps, or conditions.
FBISE exam check
- Define smog, acid rain, aqi — smog types, explain how it works, and support the answer with one relevant example.
60-second revision
- Grey coal smog vs brown photochemical.
- Coal + SO2
- Exam link: named types.
