A: Styrofoam does not decompose in the environment under normal circumstances. Much like plastic, Styrofoam is made from a polystyrene-based petroleum product that is not biodegradable. Plastic takes hundreds of years to decompose, and Styrofoam takes much longer because it is a stronger form of plastic.

Zone of wastage: Is the area in which melting or ablation rates exceed those of snowfall (Fig.2). â¢ The snow line: Is the boundary between the zone of accumulation and that of wastage, and could therefore be defined as the highest level at which winter snow melts in the summer. VI- Internal structure of a glacier.
The Sun's Interior: Radiative and Convective Zones. After covering the core, it's time to extend outward in the sun's structure. Next up are the radiative and convective zones. The radiative zone extends outward from the core, accounting for 45 percent of the sun's radius.In this zone, the energy from the core is carried outward by photons, or light units.As one photon is made, it travels about 1 micron (1 millionth of a meter) before being absorbed by a gas molecule.fter covering the core, it's time to extend outward in the sun's structure.
