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.
Upwelling is a phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface. This water replaces the warmer, usually nutrient-poor surface water. There are several types of upwelling: coastal, equatorial, large scale upwelling in the Southern Ocean, tropical cyclone and non-oceanic (in other fluid environments such as magma) upwelling. Coastal upwelling is the best known type of upwelling. The wind blows parallel to the western coasts of continents and drive surface waters away from the coast (Ekman effect). This surface water is replaces by deep, cold water, which is rich in nutrients and .
