Mountains and Hills
Mountains are high and rugged, have an elevation of at least 2,000 feet, and high relief.
Examples: Sierra Nevada with Mount Whitney (14,495 feet), Salt River Range of the Rocky Mountains above Star Valley.
Mountains have steep slopes and small summits, and are cold and snowy; glaciers form on summits.
Mountains have low temperatures, no plants at high elevations, but lower down there are small plants, and at the bases there are many trees.
They are rich in mineral deposits.
People usually live in the valleys (farming and grazing).
Hills are much smaller than mountains, have an elevation of 500-2,000 feet, and moderate relief usually less than 2,000 feet.
Hills have slopes that are steep but much shorter, and summits are more rounded.
Farming and transportation are easier in hilly areas, they tend to be populated.
Example: Berkshire Hills in Massachusetts, “West Hills” of Star Valley.
