Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection.

What can the motion of convection be compared to?

Once upon a time there a little girl named Ana. Ana was a smart girl. Everyone in Ana's school knew and liked her very much. She had a big dream of becoming spelling bee winner. Ana studied very hard to be the best she could be at spelling. Ana's best friend would help her study every day after school. By the time the spelling bee arrived Ana and her best friend were sure she would win. There were ten students in the spelling bee. This made Ana very nervous, but when she looked out and saw her dad cheering her on she knew she could do it. The spelling bee had five rounds and Ana made it through them all. She was now in the finals. During the final round James, the boy she was in the finals with, was given a really hard word and he spelled it wrong. All Ana had to do was spell this last word and she would be the winner. Ana stepped to the microphone, thought really hard and spelled the word. She waited and finally her teacher said "That is correct". Ana had won the spelling bee. Ana was so happy. She won a trophy. Ana also won a big yellow ribbon. The whole school was also happy, and everyone clapped for her. The whole school went outside. They had a picnic to celebrate Ana winning.

How many students didn't make it to the final round of the spelling bee?

863. INGREDIENTS.--The remains of a boiled calf's head, 1-1/2 pint of the liquor in which the head was boiled, 1 blade of pounded mace, 1 onion minced, a bunch of savoury herbs, salt and white pepper to taste, thickening of butter and flour, the yolks of 2 eggs, 1 tablespoonful of lemon-juice, forcemeat balls. _Mode_.--Remove all the bones from the head, and cut the meat into nice square pieces. Put 1-1/2 pint of the liquor it was boiled in into a saucepan, with mace, onion, herbs, and seasoning in the above proportion; let this simmer gently for 3/4 hour, then strain it and put in the meat. When quite hot through, thicken the gravy with a little butter rolled in flour, and, just before dishing the fricassee, put in the beaten yolks of eggs and lemon-juice; but be particular, after these two latter ingredients are added, that the sauce does not boil, or it will curdle. Garnish with forcemeat balls and curled slices of broiled bacon. To insure the sauce being smooth, it is a good plan to dish the meat first, and then to add the eggs to the gravy: when these are set, the sauce may be poured over the meat.
Is the meat removed from the bone before or after boiling?
