In what way are volcanic eruptions and meteoric impacts similar? a. both can cause global cooling. b. both can cause global warming. c. both emit oxygen gas into the atmosphere. d. both have a greater effect on weather than on climate.

A.Both can cause global cooling.

Explanation:

     According to researchers, the impact of an asteroid and volcanic eruptions probably covered the planet with harmful dust and gases, which could change the climate and caused the early extinction of many species.

    Life on earth would take thousands of years to recover from the devastation.

    "The scenario we suggested, that the impact of the asteroid would cause volcanism, reconciles with the facts we once thought was an unbelievable coincidence," said Mark Richards of the University of California at Berkeley.
