the angle of the earths tilt changes as it spins on its axis. 20,000-year cycle

Explanation:

To solve this, we match each concept (Orbital eccentricity, Axial tilt, Axial precession) with its description and cycle:

Orbital eccentricity:

• Description: The path varies from round to elliptical (relates to Earth's orbital shape).
• Effect: The Earth’s changing distance from the Sun during orbit impacts the climate, sometimes producing glacial periods.
• Cycle: 100,000 - year cycle (matches the cycle for orbital eccentricity changes).

Axial tilt:

• Description: Changes to the Earth’s orientation to the Sun affect the severity of the seasons; When the angle from vertical is greater, seasons become greater in variability (relates to the tilt of Earth’s axis affecting seasons).
• Cycle: 41,000 - year cycle (cycle for axial tilt changes).

Axial precession:

• Description: The Earth “wobbles” on its axis, which can change the orientation of the axis with celestial bodies; The angle of the Earth’s tilt changes as it spins on its axis (describes the wobble/precession of Earth’s axis).
• Cycle: 20,000 - year cycle (cycle for axial precession).

Final Matching:

• Orbital eccentricity:
• The path varies from round to elliptical.
• The Earth’s changing distance from the Sun during orbit impacts the climate, sometimes producing glacial periods.
• 100,000 - year cycle.

• Axial tilt:
• Changes to the Earth’s orientation to the Sun affect the severity of the seasons.
• When the angle from vertical is greater, seasons become greater in variability.
• 41,000 - year cycle.

• Axial precession:
• The Earth “wobbles” on its axis, which can change the orientation of the axis with celestial bodies.
• The angle of the Earth’s tilt changes as it spins on its axis.
• 20,000 - year cycle.

(If the task was to drag - and - drop, these are the correct pairings. The key was to recall the definitions and cycles of each Milankovitch cycle component: orbital eccentricity (shape of orbit, ~100k yr), axial tilt (angle of tilt, ~41k yr), axial precession (wobble of axis, ~20k yr) and match the descriptions accordingly.)
