Why
do some regions experience full-time heat while others are reckoning
with frigid temperatures and snow? And why are the seasons reversed in
the two hemispheres? Rebecca Kaplan explains how the shape of the
Earth's orbit around the Sun and the Earth's tilt on its axis affect the
amount of sunlight each region receives.
Lesson by Rebecca Kaplan, animation by Marc Christoforidis.
