Question

Which of the Milankovitch cycles changes the shape of the earth's orbit around the sun? A) eccentricity B) axial tilt C) precession D) rotation

Answer 1

The answer you are looking for is A) Eccentricity

the path of the Earth's orbit around the sun is not a perfect circle, but an ellipse. This elliptical shape changes from less elliptical (nearly a perfect circle) to more elliptical and back, and is due to the gravitational fields of neighboring planets (particularly the large ones – Jupiter and Saturn).

Hope this helps

Answer 2

Eccentricity.

Good luck!!
