Large, yes. High density, no.
A large jet can get over 12 Kilometers
The land is fertile, which supports extensive agricultural production and a high population density.
The density will not be as large as one with the same mass which is spread over a smaller volume.
An object with a high density, such as a lead ball, can have a small capacity (volume) but a large mass. This is because density is the ratio of an object's mass to its volume, so objects with high density have a lot of mass packed into a small space.
High concentration means high density, or a large amount of a particular substance in a mixture or solution.
used for large production of raising livestock in confinement at high stocking density
A large number of people (or any other organisms) living in a small space.
A city is a large human population center with a high density of buildings and other infrastructure.
An arcology is an extremely large habitat or settlement, sufficient to maintain a high human population density.
Density is mass divided by volume. Jupiter has a very large volume - its diameter is 11 times the diameter of Earth, so its volume is about 1300 times larger. It is also more massive than Earth, but not 1300 times as massive, only about 300 times as massive.
Uranium has a high density.
High altitude air density near the equator tends to be lower due to the warmer temperatures causing air to expand, reducing its density. Additionally, high humidity can further decrease air density as water vapor molecules displace nitrogen and oxygen molecules in the atmosphere. These large temperature and humidity swings at the equator can result in more dynamic changes in air density compared to other regions.
