Determining what causes the seasons is not as straightforward as determining what causes day and night. we can begin by suggesting hypotheses and then testing them for their validity. let’s start with the hypothesis that the seasons are caused by a variable distance between the earth and the sun. sort the observations or physical laws below according to whether they argue for or against this hypothesis.
a. closer light source has stronger intensity.
b. earth's closest approach to sun is in january.
c. earth's orbit is elliptical.
d. s and n hemispheres have opposite seasons

a. Closer light source has stronger intensity. argues for this hypothesis

b. Earth's closest approach to Sun is in January. argues for this hypothesis

c. Earth's orbit is elliptical. argues against this hypothesis

d. S and N hemispheres have opposite seasons argues for this hypothsis
