Answer: Meteor impacts, volcanic gases, and Milankovitch cycles (1, 2, 5)
Explanation:
Meteor impacts: It is the visible path of a meteoroid that has entered the earths atmosphere. it is debris in the solar system that varies in its size. Most meteors burn up in the atmosphere and they can hit the ground with massive force spreading that kinetic energy over a wide area of soil
Volcanic gases: these gases are trapped under great pressure in molten rock that gives eruption its explosive power for climate the key gas is Sulfur dioxide once it gets into the stratosphere Sulfur dioxide from the water mixes with water forming tiny sulfate particles , the absorb some sunlight as a result warming up the stratosphere
Milankovitch Cycles: Orbital and axial variations change the climate. Global warming is also instigated by Milankovitch Cycles
