California, State Overview

Founded in 1850
Located in western-southwestern USA
Borders Oregon (north), Nevada (east), Arizona (southeast), and Mexico (south)
Predominantly mountainous terrain, with north-south trending mountain ranges, and east-west transverse ranges.

Formation of California

Formed during the Mesozoic Era, through tectonic plate movement.
150 million years ago: An island arc collided with North America's west coast, resulting in mountain formation.
65 million years ago: The Sierra Nevada's peak elevation, shaping the valley and canyons.
Quaternary glaciation: Glaciers shaped valleys.

Sierra Nevada Characteristics

Continuous elevation increase.
Significant seismic activity.
Largest monoclinal block on earth, stretching 600 km, with a steep 3km fault drop.
Separates the Great Basin and California Valley.

Other Features

California Valley: Tectonically formed valley, rich in sediment.
Coast Ranges: Mountains running parallel to the Pacific coast.
Mojave Desert and other deserts: Areas receiving less rainfall due to high elevation and geography aspects.

Californian Mountain Ranges

Klamath Mountains: Formed at the same time as the Sierra Nevada,
Cascade Range: Formed through volcanic activity associated with the Sierra Nevada's uplift.
Coast Ranges: Central region that extends from Alaska to Southern California
Transverse Ranges: Underwent significant deformation and orientated in an east-west direction due to the San Andreas Fault.
Tehachapi Mountains: a separating range between Central Valley and Mojave Desert, connected to the Transverse mountain range
Peninsular Ranges: Extending southward from Central California.
