Humans live in this biome. In order to adapt, humans have affected the Chaparral. Chaparral biomes all over the world have been heavily affected by human activities, such as grazing, logging, building of dams, agriculture, and urbanization. This has caused plant and animal species to decline, some even nearly getting wiped out.
The key points of this model are summarized below. 1  The particles that form a liquid are relatively close together, but not as close together as the particles in the corresponding solid. 2  The particles in a liquid have more kinetic energy than the particles in the corresponding solid.
Solids are formed when the forces holding atoms or molecules together are stronger than the energy moving them apart. This module shows how the structure and composition of various solids determine their properties, including conductivity, solubility, density, and melting point. The module distinguishes the two main categories of solids: crystalline and amorphous.
