The greater the crater density, the older the surface must be old.
A lower crater density suggest a younger surface, as resurfacing through a large impact will destroy older craters.
The greater the crater density, the older the surface must be old.
High crater density is associated with older surfaces
in the scope of geologic time, how significant is the presence of humans?
they all connect
Human existence has been very brief compared to the entire expanse of geologic time.
Density = Mass/Volume or mass/size.
No . Mass
size does not relate to density
Liter is a measure of volume. Volume = mass/density.
The density is the ratio between mass and volume. So density = mass / volume
You can't, as you don't know the viscosity of the object it is hitting.
D=m/v Density equals mass divided by volume.
