Thatâs about as hot as the surface of the sun, but vastly cooler than the sunâs interior. By the way, while the heat energy produced inside Earth is enormous, itâs some 5,000 times less powerful than what Earth receives from the sun.The sunâs heat drives the weather and ultimately causes erosion. So itâs ironic that â while Earthâs heat makes mountains â the sunâs energy tears them down again, bit by bit.ut itâs producing almost as much heat as itâs losing. The process by which Earth makes heat is called radioactive decay. It involves the disintegration of natural radioactive elements inside Earth â like uranium, for example. Uranium is a special kind of element because when it decays, heat is produced.
White flour is made from the endosperm only. Brown flour includes some of the grain's germ and bran, while whole grain or wholemeal flour is made from the entire grain, including the bran, endosperm, and germ. Germ flour is made from the endosperm and germ, excluding the bran.
Cornmeal is a flour made from ground dried corn. It is a staple food in many countries around the world. You might know it as polenta or grits. We use a cornmeal and flour mix in our pizza crust to give it a distinctive flavour and texture.
