Answer:
Main properties of distribution across Earth-density, concentration, and pattern
Explanation:
Earth Density - The density of Earth is calculated by dividing the planet's mass by its volume, then simplifying from kg/km to g/cm cubed. Here is the density of the other planets in our Solar System so you can compare to Earth's.
Concentration - is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.
Pattern - structure, placement, or arrangement of objects on Earth. It also includes the space in between those objects. Patterns may be recognized because of their arrangement; maybe in a line or by a clustering of points.
