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.
Plate Tectonics. The main force that shapes our planet s surface over long amounts of time is the movement of Earth's outer layer by the process of plate tectonics. This picture shows how the rigid outer layer of the Earth, called the lithosphere, is made of plates which fit together like a jigsaw puzzle.hen two sections of the Earth's crust collide, one slab of crust can be forced back down into the deeper regions of the Earth, as shown in this diagram. This process is called subduction.
