Earth rotates on a tilted axis and orbits the Sun Objective: Explain why Earth has day and night.

Earth’s tilted axis and orbit cause seasons. The Sun’s gravitational pull puts Earth’s path in a round orbit Revolution- Earth in its orbit around the Sun 1 year
Seasons Are caused by the position of Earth’s axis relative to the direction of sunlight Near equator temperatures mostly same year round Near the poles large temperature changes Changes in the amount of sunlight are due to the tilt of Earth’s axis
Equinox- sunlight shines equally on the northern and southern hemisphere Solstice- Sunlight is maximum in only one hemisphere Happen around the 21st day of certain months
September Equinox: 1/2 the sunlight is in each hemisphere. December Solstice: Less than ½ of the northern hemisphere is sunlight.
