easy Q12 of 15
General Science - Physics (Basics)
What is the main cause of global warming?
AIncrease in Earth's distance from the Sun
BOzone layer depletion
CDecrease in volcanic activity
DAccumulation of greenhouse gases in the atmosphere
Step-by-Step Solution

  1. Step 1: Understand global warming cause

    Global warming is the rise in Earth's average surface temperature.

  2. Step 2: Analyze causes

    Accumulation of greenhouse gases traps heat, causing temperature rise. Distance from Sun and volcanic activity changes are not main causes. Ozone depletion affects UV radiation, not global warming directly.

  3. Final Answer:

    Accumulation of greenhouse gases in the atmosphere → Option D

  4. Quick Check:

    Global warming cause = Greenhouse gas accumulation ✅
Quick Trick: Link global warming directly to greenhouse gas buildup.
Common Mistakes:
  • Confusing ozone depletion with global warming cause.
