4. explain why and how often we have leap years.
5. at what compass point does the sun appear to rise in the morning?
6. andrew sees the sun reaching its highest pointing the sky, then it begins to
descend. at what time does it begin to descend?

it will be bbb bbb bbb bbb bbb bbb bbb bbb

it is either c or d and i know for sure it is not a or b

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
