What is axial tilt?
the angle of the earths axis relative to its orbital plane
Varies between 22.1° and 24.5° over 41,000 years
What is axial tilts influence on climate?
Effects the intensity of seasons
What does small axial tilt result in?
Smaller tilt results in milder seasons
Less tilt may prevent ice sheets from melting, contributing to glacial periods
What does a greater axial tilt result in?
Larger tilt results in more intense seasons
Linked to inter-glacial periods
