The rock cycle describes the way that rock material cycles through Earth's crust. All rocks start out as lava or magma that cools into igneous rock. An igneous rock must then be weathered into sediments for the next stage of the cycle. Sediments are compressed and cemented to become sedimentary rock. Metamorphic rock forms when rocks are heated and squeezed deep in Earth's crust. New igneous rock forms when metamorphic rock is heated so much that it melts into igneous rock. All rocks go through this cycle over and over again.

Select the sentence in this paragraph that explains why infectious diseases are density-dependent.

Infectious diseases are diseases that can spread from one host to another. Infectious diseases are a density-dependent factor. An increase in density increases the rate of host interactions, which in turn hastens the spread of the disease. This axiom supports health professionals’ recommendations that people with infectious diseases—such as the flu—stay home and avoid interactions with other people. Health professionals are able to find the initial source of the infection through what is known as contact tracing.
