Why are temperatures cooler in the
northern hemisphere at this time?

Earth spins on an angle, so the Northern hemisphere is towards the sun in the summer, making it warmer and having the temperature increase, so the opposite of that is that in the winter, the Northern Hemisphere tilts away from the sun, making the temperatures decrease.

Hope this helps!

Explanation:

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
