Two motions shape our calendar. The Earth spins like a top, swinging us in and out of sunlight to make day and night, and it circles the Sun once a year, leaning over as it goes to give us the seasons.
The Earth rotates on its tilted axis once every 24 hours, giving day and night, and orbits the Sun once a year. The tilt of the axis causes the seasons, as each hemisphere leans toward or away from the Sun.
The Earth rotates on its axis once a day, giving day and night, and orbits the Sun once a year. The Earth’s axis is tilted, which gives the seasons.
Day and night come from rotation; the seasons come from the tilt of the axis, not from changing distance to the Sun.
Spin the Earth and orbit it round the Sun, and watch day, night and the seasons appear.
Four quick checks. Each correct answer earns XP and lights this skill on your star map.
Day and night are caused by the Earth...
The Earth takes about how long to rotate once on its axis?
The Earth orbits the Sun once every...
The seasons are caused by...
Rotation gives day and night, the orbit gives the year, and the tilt gives the seasons.
The seasons are caused by the tilt of the Earth’s axis, not by the Earth being nearer to or further from the Sun. Day and night come from the Earth’s rotation, not from its orbit.
