A. A 1/4-ounce envelope of unflavored gelatin contains 1 tablespoon, which is enough to gel about 2 cups of most clear liquids. Keep in mind that certain foods-figs, ginger root, guava, kiwifruit, papaya, and pineapple-contain an enzyme that prevents gelatin from thickening.
Upwelling in the coastal ocean can be due to a number of factors. In most situations the upwelling is wind driven and its effect on currents, stratification and nutrient supply determined by topographic detail such as water depth and the shape of the coastline.
Causal mechanisms [edit]. Favourable geology and climate are the principal causal mechanisms of rockfall, factors that include intact condition of the rock mass, discontinuities within the rockmass, weathering susceptibility, ground and surface water, freeze-thaw, root-wedging, and external stresses.
