Which explains why many places on Earth experience four seasons each year rather than just
two?
A As Earth orbits around the Sun, the axis changes its amount of tilt, which causes a change in
the amount of sunlight reaching Earth.
B Eastern and western hemispheres each experience a different season when Earth is at each
position shown and when it is 14 and 34 around its orbit.
C Halfway between the positions shown, the amount of solar energy received is less than when
the axis is pointed toward the Sun, but more than when the axis is pointed away from the
Sun.
D When Earth is 14 and 3/4 around its orbit, the northern hemisphere points directly at the Sun.
