If switching from another form of memantine to the extended-release form, follow your doctor's instructions carefully. Do not switch forms of memantine without talking to your doctor first. Use this medication regularly to get the most benefit from it.
(J. Louie). The earth is divided into four main layers: the inner core, outer core, mantle, and crust. The core is composed mostly of iron (Fe) and is so hot that the outer core is molten, with about 10% sulphur (S).The inner core is under such extreme pressure that it remains solid.irculation and convection of electrically conductive molten iron in the Earth's outer core produces the magnetic field. To make the magnetic field, the convection must be relatively rapid (much faster than it is in the plastic mantle), so the core must be fluid.
The outer core consists of hot lava that is comprised mostly of iron and nickel. This layer is so hot that all metals in it are in a liquid state. Iron and nickel are common metals found across the planet, and these metals exist in solid form on the Earth's surface. In the outer core, they form an alloy.
