1) why is it colder in winter than in summer? (give two reasons) 2) what would seasons be like if earth's axis were tilted more than 23.5 degrees? 3) describe how june 21 and december 21 would be like on the north pole and equator. note: if you have the time, and patience, do all of them, if not, do 1. i know number 1 is the easiest, but try to do 2 and 3.

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
