Answer to Question 1

Answer: B

Answer to Question 2

Answer: Occluded fronts may form when a faster-moving cold front catches up to the warm front ahead. If the overtaking air mass is colder, it produces a cold-type occlusion. If the trailing air mass is warmer, the model suggests a warm-type occlusion will form. Occlusions also arise from deformations in the flow around a cyclone. For example, occlusions sometimes occur when the circular core of low pressure near the junction of the cold and warm fronts changes shape and stretches backward, away from its original position at the junction of the cold and warm fronts.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
