Answer to Question 1

The Moon lacks an atmosphere which means it has no weather. It also lacks a molten interior which means it has no plate tectonics. On the Moon the major form of erosion is meteorite bombardment, which is a very slow process. On Earth, wind and rain cause weathering (rapid erosion) of crater features. Plate tectonics is constantly changing the surface of the Earth, creating new crust and recycling old.

Answer to Question 2

TRUE

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.
