Answer:
Cycles also play key roles in Earth’s short-term weather and long-term climate. A century ago, Serbian scientist Milutin Milankovitch hypothesized the long-term, collective effects of changes in Earth’s position relative to the Sun are a strong driver of Earth’s long-term climate, and are responsible for triggering the beginning and end of glaciation periods (Ice Ages).
The shape of Earth’s orbit, known as eccentricity;
The angle Earth’s axis is tilted with respect to Earth’s orbital plane, known as obliquity; and
The direction Earth’s axis of rotation is pointed, known as precession.
