Document Summary
Water travels along fluvial rills: fluvial = formed by water flow, rills = shallow, narrow soil erosion grooves formed in slopes (hillsides, mountains) by water flow. Rills merge and empty into larger bodies of water such as creek and streams. Creeks and streams merge to form larger and larger rivers. Rivers empty into the ocean at the mouth of the river (estuaries here) The ms river is fed by 31 of the 48 contiguous states: sediment soil particles, sand, and other mineral matter eroded from land and carried in waters. Surrounded by divides (a ridge of land separating distinct watersheds) The great divide: continental divide that splits north america into 2 watersheds: east and west. Usually in areas with low elevation and high water table; poorly drained. Contains unique types of soil, plants, and organisms: inland wetlands - found along streams, lakes, rivers, and ponds; include bogs, marshes, swamps, river overflow lands, coastal wetlands typically associated with estuaries.
