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.
Crystals can form when a supersaturated liquid that contains a dissolved mineral cools. In this activity, a supersaturated solution is made using hot water and borax (a soft crystal). The hot water causes the water molecules to move further away from each other so that more of the borax can dissolve into the solution.
