Answer 1

Answer:

When looking down on the North Pole, Earth always rotates counter clockwise. It is actually a simplified view of the earth's rotation because the tilt of the earth's axis with respect to the plane of the earth's orbit means that sometimes sunrise occurs slightly earlier or later along the same longitude.

Explanation:

This view is actually accurate enough, however, to get a general picture of whether or not something will rise with the sun, or set around the time of sunrise, etc. The model you have made is also accurate enough for deciding when something will transit. Transit means to cross the meridian for a given observer.International Date Line

If you travel eastward, you will "lose one hour" (set your clock ahead one hour) for every time zone you pass through.  If you go all around the Earth traveling east, you will have to set your clock ahead 24 times, for a total of 24 hours.

This would put you one day ahead of your friends when you got home, and that would mess things up very badly.  We solve this problem by having an International Date Line.  The International Date Line is approximately the half circle on the far side of the earth, opposite the Prime Meridian.  When you cross the International Date Line going eastward, you set your clock back by 24 hours, this cancelling the 24 hours you set the clock ahead.

In this way, you have traveled around the world, setting your clock ahead one hour at a time, for 24 times.  When you cross the date line heading eastward, you automatically set your clock back by 24 hours, or one day.  So you and your friends, and all the countries of the world for that matter, will agree with you on what day it is.
