the ratio of mass to volume
B
all of the above.
C
how much matter is in a space

not move.

A
increases and it sinks.
B
decreases and it sinks.
C
increases and it floats.

it expands and is less dense than the air around it.
D
it expands and is more dense than the air around it.
9) When two tectonic plates collide, one with continental crust and the other with oceanic crust,
A
the continental crust will be pushed under because it is less dense.
B
the continental crust will be pushed under because it is more dense.
C
the oceanic crust will be pushed under because it is more dense.
D
the oceanic crust will be pushed under because it is less dense.
10) Ice floats in liquid water because
