Answer to Question 1

Answer: Weathering is the interaction of the geosphere with the atmosphere, hydrosphere, and biosphere. Physical weathering disaggregates rocks by mechanical means. The most effective agent of physical weathering is the freezing and thawing of water. Other processes include salt weathering, cracks formed by temperature-induced expansion and contraction, and tree roots growing in rocks. Chemical weathering occurs when minerals react with water and oxygen. The two products of chemical weathering are ions dissolved in aqueous solutions and new minerals formed by hydrolysis and oxidation.

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.
