it quite less than that in places of low altitude.
The Crust
its Density
because some places have more things than other places! like the US compared to AFRICA!
I haven't seen it in context, so I am not sure. However, I would expect it to mean, the density, compared to that of some other substance.
Narrow European streets create the illusion of high density suburbs
Compared to a low density substance and all other things being equal, it would be heavier.
It is ranked 45th in population and 6th in population density.
Weight and length cannot be compared without a few other factors such as shape, other dimensions, and density
Energy density of petrol products are low when compared to hydrogen and other fuels.
Difficult terrain
seasonal flooding
practically any gas station, grocery store, or other places like that - yeah true
