Document Summary
A place where water is stores is called a reservoir ; movement form one reservoir to another is called a flux. Most of the water that is evaporates from the ocean returns to the ocean as rain and snow. The volume of ice is decreasing due to global warming. Water has to go somewhere: mostly stored on land as glacial ice, a small amount could be stored on land as groundwater, a very small amount could be placed in the atmosphere. The water cycle: stream flow is part of the hydrologic cycle, major parts of the hydrologic cycle, evaporation, precipitation, interception, infiltration surface flow. Tributary: rivers that feed into bigger rivers. Continental divides separate drainages that flow to different water bodies. Bed load- materials that roll, slide, bounce along bottom suspended load- silt and clay particles that are carried in the water. Decrease in water velocity affects sediment transport. Coarse material first (boulders), finer material (sand)
