Which of the following is not part of the milankovitch theory? eccentricity tilt precession temperature

The Milankovitch theory tries to explain the differences in climates and temperatures around the world over time based on the changes in earth's orbit, axial rotation and axial tilt.  so i think it would be eccentricity 

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )
