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.
Tectonic shift is the movement of the plates that make up Earthâs crust. The Earth is made up of roughly a dozen major plates and several minor plates. The Earth is in a constant state of change.Earthâs crust, called the lithosphere, consists of 15 to 20 moving tectonic plates.The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earthâs mantle and fit snugly against one another.he Earth is in a constant state of change.
