Eccentricity (definition)

Changes the difference in solar intensity when Earth is closest to and farthest from the Sun.

Obliquity (definition)

Changes the strength of the seasons, especially at high latitudes.

Precession (definition)

Changes in which hemisphere has summer when Earth is closer to or farther from the Sun
