Answer:
B. Rays of sunlight hit less directly. The days are shorter and temperature colder.
Explanation:
When the north pole tilts away from the sun, the sun's rays are displaced below the equator line, that is, towards the southern hemisphere. It causes the northern hemisphere to receive fewer solar rays and to receive them indirectly, which leaves the atmosphere cooler and decreases the length of the day. This moment coincides with winter and autumn in the northern hemisphere. This inclination of the north pole lasts six months and after that period the moment of inclination of the south pole begins, which causes the sun's rays to be displaced towards the northern hemisphere.
The density of an object or quantity of matter is its mass divided by its volume. ... Non-standard conditions can result in a change of volume, affecting the density of the materials. Also, certain temperatures and pressures can result in a change the state of the matter, which also affects the density.
I find that the best answer is the following one:
c. determined by factors outside our control
For example, even though life is very hard in the very hot and the very cold regions, we can't control it: so this is an example of a physical environment that is hard to control.
In comparison, it is often easier to describe than our social environment.
