plinycmu (core; planetary layer)
$j_1$ is the core (innermost layer) of planet/moon $p_1=j_2$, of
composition $p_3$.
Notes: Cf. {plini}, {jicmu}.

bacplinycmu (outer core; planetary layer)
$b_1=j_1$ is the outer core (layer above the core) of planet/moon
$p_1=j_2$, of composition $p_3$.
Notes: Cf. {plini}, {jicmu}.

jduro'i (mantle; planetary layer)
$j_1=r_1$ is the mantle of planet/moon $r_3$, of composition $j_2=r_2$.
Notes: Cf. {rokci}.

galjduro'i (upper mantle; planetary layer)
$j_1=r_1$ is the upper mantle of planet/moon $r_3$, of composition $j_2=r_2$.
Notes: Cf. {rokci}.

tumpi'a (crust; geological solid shell)
$t_1=p_1$ is the geological crust (outermost solid shell) of
planet/moon $p_2$, of composition $x_3$.
Notes: Such planets as Jupiter and Saturn have no crust. Pedantically,
the p2 is the planet/moon's mantle. Cf. {tumla}, {pilka}.

flemomvacri (troposphere)
$f_1=v_1$ is the troposphere (the lowest layer of atmosphere) of
planet/moon $v_2$, of composition $x_3$.
Notes: From 0 to 17 km in altitude. The Earth's troposphere contains
approximately 75 percent of the atmosphere's mass and 99 percent of
its water vapor and aerosols. Cf. {vacri}.

dukmomvacri (stratosphere)
$d_1=v_1$ is the stratosphere (the second layer of atmosphere) of
planet/moon $v_2$, of composition $x_3$.
Notes: From 17 to 50 km in altitude. It is stratified in temperature,
with warmer layers higher up and cooler layers farther down. This is
in contrast to the troposphere. Cf. {vacri}.

mijmomvacri (mesosphere)
$m_1=v_1$ is the mesosphere (the third layer of atmosphere) of
planet/moon $v_2$, of composition $x_3$.
Notes: From 50 to 85 in altitude. Cf. {vacri}.

glamomvacri (thermosphere)
$g_1=v_1$ is the thermosphere (the fourth layer of atmosphere) of
planet/moon $v_2$, of composition $x_3$.
Notes: From 85 to over 640 km in altitude. The highly diluted gas in
this layer can reach 2,500 °C (4532°F) during the day. Cf. {vacri}.

barmomvacri (exosphere)
$b_1=v_1$ is the exosphere (the uppermost layer of atmosphere) of
planet/moon $v_2$, of composition $x_3$.
Notes: From 500-1000 up to 10,000 km in altitude. In the exosphere, an
upward travelling molecule can escape to space if it is moving fast
enough to attain escape velocity; otherwise it will be pulled back to
the celestial body by gravity. Cf. {vacri}.
