The melting of the polar ice caps is expected to raise sea levels throughout the world as a result of climate change. There are four possible answers to this question: (a) north pole, (b) south pole, (c) both north and south poles equally; (d) neither north nor south pole; or (e) neither pole.
1) How many kilometers are spanned by an arc of 0.5° latitude (Dj = 1°) along the DateLine?
2) At what latitude is the zonal distance spanned by an arc of 1° longitude (Dl = 1°) exactly half as long as the equivalent meridional distance spanned by an arc of 1° latitude (Dj =1°)?
The earth revolves around the sun in exactly 365 1/4 days which is equivalent to 1 year. To make up for the loss of 1/4 day, the calendar was adjusted so that we have a leap year for every 4 years. If the earth were to speed in its motion slightly so that a year would be completed in exactly 365 days and 6 hours, how often would we need to have a leap year?
