21. When the obliquity is higher, the poles receive more sunlight, causing those materials to migrate away. 22. Sutures are closely spaced and slope forward from venter to dorsum with the obliquity increasing as growth progressed. 23. Modulation of the precession driven insolation cycle is the primary impact of obliquity on the North African Monsoon. 24. As explained in the equation of time article, this is due to the obliquity of the ecliptic ). 25. Regular changes in climate may be due to variations of a planet's tilt ( called obliquity ). 26. His name is lent to " Litzmann's obliquity ", which is another name for posterior asynclitism. 27. The planet could remain at an obliquity of 60?to 90?for periods as long as 10 million years. 28. These parameters include the precession of the equinoxes, obliquity , and eccentricity as put forth by Milankovitch theory. 29. His name is also lent to " Naegele's obliquity ", also known as an anterior asynclytism. 30. "That profit-seeking paradox, like the conundrum of happiness, illustrates the power of obliquity .
