A computer model predicts that a rocky planet has a constant average temperature while orbiting its star.
The model is changed so that the concentration of carbon dioxide in the atmosphere decreases and storms spread dark volcanic dust over large areas of pale ground.
Explain why the planet initially has a constant average temperature and how each of the two changes could affect its average temperature.
