California is home to various geographical regions, each with its own distinct elevation characteristics. The coastal regions, including cities like San Francisco, Los Angeles, and San Diego, are generally at or near sea level. However, as you move inland, the elevation gradually increases as you encounter rolling hills, valleys, and mountain ranges. The Sierra Nevada, which runs along the eastern edge of the state, is a prominent mountain range with several peaks above 10,000 feet (3,048 meters) in elevation.
In summary, California's elevation varies greatly, with the lowest point being below sea level and the highest point reaching almost 15,000 feet above sea level. This diversity in elevation contributes to the state's rich and varied landscapes, from desert basins to towering mountain peaks.
