Glaciers are born in rocky wombs above the snow line, where there is sufficient winter snowfall and summer cold for snow to survive the annual melting. The long gestation period of a glacier begins with the accumulation and gradual transformation of snowflakes. Soon after they reach the ground, complex snowflakes are reduced to compact, roughly spherical ice crystals, the basic components of a glacier. As new layers of snow and ice, snow that survives the melting of the previous summer, accumulate, they squeeze out most of the air bubbles trapped within and between the crystals below. This process of recrystallization continues throughout the life of the glacier.

The length of time required for the creation of glacier ice depends mainly upon the temperature and the rate of snowfall. In Iceland, where snowfall is heavy and summer temperatures are high enough to produce plenty of meltwater, glacier ice may come into being in a relatively short time say, ten years. In parts of Antarctica, where snowfall is scant and the ice remains well below its melting temperature year-round, the process may require hundreds of years. The ice does not become a glacier until it moves under its own weight, and it cannot move significantly until it reaches a critical thickness the point at which the weight of the piled-up layers overcomes the internal strength of the ice and the friction between the ice and the ground. This critical thickness is about 60 feet. The fastest moving glaciers have been gauged at not much more than two and a half miles per year, and some cover less than 1/100 inch in that same amount of time. But no matter how infinitesimal the flow, movement is what distinguishes a glacier from a mere mass of ice.

12. The word “constraints” in the passage is closest in meaning to ____.

Pottery refers to dishes, plates, cups and cooking pots made out of clay. Chinese pottery was invented during the Neolithic period (5,000- 2,2’00 BC) and it was molded by hand. Before this time, people had been nomadic, making it difficult to carry heavy, breakable pieces of pottery. At first, pottery was made by pushing a hole into a ball of clay or by taking a piece of clay and coiling it up into a pot shape. Many early pots were simple lumps of clay. However, people rater discovered that clay, when placed in an open fire, hardened. This technique, known as firing, soon became common practice in pottery production.

People used pottery as a way of forming their social identity or showing who they were and how they were different from other people. Many of the designs that were used on pottery were usually borrowed from those already found on clothing and garments. The decoration of pottery began with simple incisions, which were later painted on. Gradually, plants, animals, and human figures were included on the vases. Mythological scenes were common as were dancers, musicians, and images from everyday life.
