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.
The rising of hot rock from the mantle to Earthâs surface is called upwelling. This process adds new material to tectonic plates. In a June 2013 study in Nature, Conrad and other researchers found massive, extra-hot regions of mantle beneath Africa and the central Pacific Ocean.
