Question

7. Atmospheric changes in Earth's history have caused large temperature changes through time. Explain

Answer 1

Answer:

On the basis of evidence of mass extinction that have resulted due to the changes in climate of earth.

Explanation:

• Large changes in the earth's climate are controlled by the concentration of greenhouse gases. The rate of carbon dioxide is increasing at a rate more than 100 times greater than has been in the past 800,000 years and this is four-time greater than the time of humans on the planet.

• Changes associated with the earth's orbit around the sun and its changing composition inform us about the modern-day climate changes.
