C H C Y C L E S • Cycle in perihelion (precession of our orbit) • Axial precession about our axis; like a wobbling spinning-top • Shape of our orbit becomes more and less elliptical. • We are half way through these cycles
as it spins, this creates our seasons • The Earth’s spin creates huge speed differentials, and the Coriolis effect • The Earth’s spin, and the gravity of the Moon and Sun contribute to tides • Our orbit takes us into the path of other orbiting bodies • Periodic changes in our spin, tilt and orbit affect the global temperature
