Answer:
"Crust" refers to a
terrestrial planet's outermost surface.
In general, the Earth's crust is divided into
older, thicker continental crust and younger, denser oceanic crust.
...
The thin, 40-kilometer (25-mile) deep crust of our planet — just
1 per cent of Earth's mass — contains all known universe existence.
Explanation:
Continental crust is thicker, 22 miles (35 km) on average and less dense than oceanic crust, which accounts for its mean surface elevation of about 3 miles (4.8 km) above that of the ocean floor (Archimedes’ principle). Continental crust is more complex than oceanic crust…

Answer:
78kg
Explanation:
Let water density 
. We can calculate the buoyant force generated by water displaced by the air mattress from the volume of the mattress:
where l, w, t are the length, width and thickness of the mattress, respectively.
Let g = 10 m/s2. The buoyant force is then:
Let g = 10 m/s2. The gravity force acting on the mattress is
So the mattress can still support an additional gravity of 800 - 20 = 780N or 78kg
