7. Explain how earth's orbit changes global temperatures

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.
