The core of the earth is a central mass __29__ of two distinct parts: a solid inner core and a liquid outer core. It is believed __30__ nearly twice as dense __31__ the mantle and, although it has only 16.2% of the earth's volume, it has 31.5% of the earth's mass. The conclusion that the outer core is liquid is based __ 32__ the fact that S waves, which will not pass __33__ a liquid, are not transmitted through the core. A solid inner core is suggested __34__ the high pressure and density which __35__ near the center of the earth. Presumably, the increase __36__ pressure at depth causes the core to __37__ from liquid to __38__. The magnetic field further __39__ the assumption that __40__least part of the core is liquid.
