You are presented with the question "What can cause a short-term cooling of the Earth's climate?" and the following answer choices: 
- electromagnetic energy
 - a hemisphere is tilted away from the sun
 - The movement of tectonic plates.
 - Greenhouse gases
 - fissures of hot, acidic water
 - energy of moving objects
 - wind and erosion
 - exposure to cold

Now knowing that the movement of tectonic plates causes volcanic eruptions and volcanic eruptions can cause short-term cooling of the Earth's climate, choose the best answer.
