Bush. Musharraf agreed to give the U.S. the use of three airbases for Operation Enduring Freedom. United States Secretary of State Colin Powell and other U.S. administration officials met with Musharraf.

Input: Article: Wood, in the strict sense, is yielded by trees, which increase in diameter by the formation, between the existing wood and the inner bark, of new woody layers which envelop the entire stem, living branches, and roots. This process is known as secondary growth; it is the result of cell division in the vascular cambium, a lateral meristem, and subsequent expansion of the new cells. Where there are clear seasons, growth can occur in a discrete annual or seasonal pattern, leading to growth rings; these can usually be most clearly seen on the end of a log, but are also visible on the other surfaces. If these seasons are annual these growth rings are referred to as annual rings. Where there is no seasonal difference growth rings are likely to be indistinct or absent.

Now answer this question: What is the process of trees growing out to get bigger around called?

Output:
secondary growth
