Rotation – spinning on its axis Earth rotates at 1670km/hr(1070mph) at the Equator.

Angle of inclination-The Earth is tilted at 23.5°

Changes in the angle that sunlight strikes the Earth’s surface cause the seasons.

When tilted away from the sun, the rays are at a low angle = low intensity=cooler.

When tilted towards the sun, the rays are at a high angle = high intensity=hotter.

Revolution – a body in space traveling around another. Earth revolves at 108,000km/hr(66,660mph)

Equinox – the moment the sun crosses the equator. 2 per year: spring = vernal, fall=autumnal

Solstice – the sun is as far North or South as it will go. 2 per year: summer(longest day of the year), winter(shortest day of the year)
