Why do we have day and night? 为什么会有白天和黑夜？

Together, we discover that the Earth never stops spinning, what that means for every family on the other side of the world right now, and why we never feel the ground moving beneath our feet.

我们一起发现，地球从未停止转动，这对此刻世界另一端的每一个家庭意味着什么，以及为什么我们从未感到脚下的地面在动。

Perfect for little listeners aged 5–8.
