Two main factors that cause population growth are high birth rates and low death rates. When birth rates exceed death rates, the population increases over time. Additionally, immigration can also contribute to population growth by adding individuals to the existing population.
The two main factors that affect density are the mass of an object and its volume. An increase in mass or a decrease in volume will lead to an increase in density, whereas a decrease in mass or an increase in volume will result in a decrease in density.
