10. I-2-9 Add percentages to the following diagram Click for hint Click for answer Click for Next Question

11. Name four reasons why developed conditions typically change the fate of precipitation in the water cycle I-2-10 • _______________________________________________(Water is transported rapidly away via storm drains and is not allowed to stand in pools.) • ______________________________________________(Natural vegetation is replaced by buildings, pavement, etc.) • _______________________________________________(This can result in a lower water table and can affect baseflow.) • ________________________________________________. (Streamflow becomes more intense during and immediately after storms.) • Less precipitation is evaporated back to the atmosphere. (Water is transported rapidly away via storm drains and is not allowed to stand in pools.) • Less precipitation is transpired back to the atmosphere from plants. (Natural vegetation is replaced by buildings, pavement, etc.) • Less precipitation percolates through the soil to become ground water. (This can result in a lower water table and can affect baseflow.) • More surface runoff is generated and transported to streams. (Streamflow becomes more intense during and immediately after storms.)

15. I-2-14 The _______________is the area of natural vegetation extending outward from the edge of the stream bank. Riparian zone Number 3 on this diagram. Click for hint Click for answer Click for Next Question

16. I-2-15 • The ____________________ includes both an upper bank and a lower bank. The lower bank normally begins at the normal water line and runs to the bottom of the stream. The upper bank extends from the break in the normal slope of the surrounding land to the normal high water line. stream bank Don’t overthink, simple answer Click for hint Click for answer Click for Next Question

20. I-2-19 • __________________________ are distinct habitats within the stream where the velocity of the water is reduced and the depth of the water is greater than that of most other stream areas. They usually have soft bottom sediments. Pools You may like to swim in these. Click for hint Click for answer Click for Next Question
