<u>the Paleozoic Era </u>
The Precambrian era describes a period of time that pre-dates Cambrian. This time typically references the entire period of the history of earth before the formation of rocks containing identifiable fossils occurred. It covers the majority of Earth’s history and is divided into the Hadean, Archean and the Proterozoic era.
Just before the Cambrian eruption, in the Paleozoic Era the environment was oxygenated, culminating in an explosion of new life in the Proteozoic Eon (2500-541 million years ago) in the form of primitive blue-green algae named cyanobacteria and oxygen based species. Multicellular species followed later, along with structure at higher levels, and complex life. Oxygen levels grew gradually over this period of time, from low levels.

Answer:
Geological processes are those process that occurs on the surface and subsurface regions of the earth crust. They facilitate in shaping the Earth, and helps in concentration of resources over a region. These processes occurred millions of years ago, the chances are their that they will occur in future as well. Some of the major features of the California landscape develop as a result of plate tectonics and other features develop due to the process of erosion under the influence of wind, water, ice and other features.
