Cabinets usually have one or more doors on the front, which are mounted with door hardware, and occasionally a lock. Many cabinets have doors and drawers or only drawers. Short cabinets often have a finished surface on top that can be used for display, or as a working surface, such as the countertops found in kitchens.
Plates at our planet s surface move because of the intense heat in the Earth s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.
Actually the newest theory on the movement of the plates is not because of convection but the subducting slab pulling apart the plates, where it pulls them apart new crust forms at mid-ocean ridges. The heat in the center of the earth comes from both pressure and radioactive decay. Source(s): I am a geologist.
