Answer:
Polar Region
Explanation:
Along the west coast of the U.S., the California Current carries cold water from the polar region southward, keeping the west coast relatively cooler than the east coast.
Sacramento River geologic unit details are described below.
Explanation:
1.The Sacramento River is the main river of Northern California in the United States, and is the largest river in California. Rising in the Klamath Mountains, the river flows south for 400 miles (640 km) before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay.
2.Sacramento River, river is rising in the Klamath Mountains, near Mount Shasta (in Siskiyou county), northern California, U.S. The river flows 382 miles (615 km) south-southwest between the Cascade and Sierra Nevada ranges, through the northern section (Sacramento Valley) of the Central Valley.
3.This river forms a common delta with the San Joaquin River before entering Suisun Bay, the northern arm of San Francisco Bay. Its principal tributaries are the Pit, McCloud, Feather, and American rivers. Total drainage area is about 27,100 square miles (70,200 square km); average annual runoff is 22 million acre-feet (27 billion cubic metres).
4. Shasta, Keswick, and Oroville dams are key features of the Central Valley and Feather River irrigation and power projects, which serve southern portions of the state. California’s largest river, the Sacramento is navigable for 256 miles (412 km) and accommodates oceangoing vessels as far as the city of Sacramento.The name Sacramento was originally given to the Feather River by Gabriel Moraga in 1808; it was later applied to the main channel (originally called Rio de San Francisco). Scene of the Gold Rush of 1849, the river flows through one of the world’s richest agricultural regions. The river harbours hundreds of species of fish, and the Sacramento River National Wildlife Refuge, in several units, protects several ecosystems.
