Question

the graph shows data from ice cores. which claim does the graph support? a. it takes millions of years to change earths greenhouse gas levels. b. neither greenhouse gas levels nor temperatures are changing on earth. c. greenhouse gas levels are unrelated to temperature fluctuations on earth. d. earths greenhouse gas levels are rising at an increasing rate.

Explanation:

The graph shows atmospheric carbon - dioxide levels over time from 1000 AD to 2000 AD. The curve is relatively flat initially but then shows a sharp upward trend starting around 1800 AD, indicating an increasing rate of rise in greenhouse gas levels. Option A is incorrect as the graph only shows a time span of a thousand years, not millions. Option B is incorrect as the graph clearly shows a change in greenhouse gas levels. Option C is incorrect as the graph doesn't address the relationship between greenhouse gas levels and temperature fluctuations.

Answer:

D. Earth's greenhouse gas levels are rising at an increasing rate.
