  4. Carbon dioxide
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Nitrogen makes up the majority of the Earth's atmosphere but is not a greenhouse gas, unlike methane, water vapor, and carbon dioxide.

Multiple choice

Methane is formed by

  1. the decomposition of animal and vegetable matter

  2. the decomposition of vegetable matter

  3. the decomposition of animal matter

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Decomposition (or rotting) is the process by which organic substances are broken down into simpler forms of matter and produces a gas called methane.

Multiple choice

Biogas mainly contains

  1. carbon dioxide

  2. methane

  3. hydrogen

  4. ethane
Reveal answer Fill a bubble to check yourself
B Correct answer
