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.
Downwelling. The importance of upwelling to surface organisms is matched by the need of sea bottom life for downwelling, or the sinking of surface water. Surface water can be forced downward by the pressure of the âpileâ of water that forms where currents converge or wind drives the sea against a coastline.tudy the graphics and photographs illustrating upwelling and downwelling, then answer the questions about each process. Maps of the worldâs major surface and deep currents are included as resources to help you understand where and how upwelling and downwelling occur.
