There are two main<span> types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.</span>

Pathogens can adapt more quickly than hosts since they have higher populations and faster generation periods.
Pathogens, of course, have the advantage in this evolutionary game because they can change far more quickly than the hosts—especially in long-lived animals like humans—due to their high population numbers and rapid generation rates. The relationship between surface area and complement activation shows how bacterial pathogenicity may be influenced by tiny size. The region of the microbial surface may also have a role in their action since other antimicrobial agents are focused there. A pathogen reacts with the host and creates infection, which results in the host being ill. Any dangerous microbial agent, including bacteria, viruses, protozoa, fungi, and helminths, might be considered a pathogen.
