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.

Its true that seasons caused due to the rotation of earth around its axis.

Explanation:

If we take the hypothesis as seasons are caused due to the variable distances between the earth and the sun in the center of the solar system. Some observatory laws of physics tell us that when earth is in a straight line with sun and opposite is moon high and low tidal bulges occur as a result of gravity. Similar, the process of day and night also occur at the surface of the earth. Due to the earth with a tilt of 23.5 on its axis. One can easily ascertain the role it plays information about the weather at various latitudes of the climate.  Taking into account sun's angle of incidence.Diurnal heating and cooling of the earth are also related to the same processes and hypothesis that govern the law of thermodynamics and energy transmission to space from radiation black body at night.

The figure is not necessarily a parallelogram because only one diagonal is bisected and only one pair of sides is congruent.
