Answer:
Volume= 4 cm³
Density= 2 g/cm³
Explanation:
We have the following data:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
See that river on the bottom? That water has been flowing in the canyon for a long time and has slowly been chipping away at the rocks to give what you see today.
B. erosion from the water
Depending on what happens with the environment if its a decline in resources it could completely fall and tear itself apart it just depends really on what you think of just make up a situation in your head and talk about that
