Unit 4: The Hydrologic Cycle

Question 1

What are the 6 properties of water?

Answer 1

1. Hydrogen bonding
2. 3 different states
3. Boiling and freezing points
4. Adhesion and Cohesion
5. Capillary Action
6. Universal Solvent

Question 2

What are factors affecting infiltration?

Answer 2

Precipitation (amount and characteristics)

Base flow (groundwater seeping into the bed and banks of the stream)

Soil Characteristics (clays absorb water less readily than sandy soils)

Soil saturation (already saturated soils cant absorb more water > more run off)

Land cover (vegetation, development, drainage diversions)

Slope (runoff)

Evapotranspiration

Question 3

What are Factors affecting transpiration

Answer 3

Temperature (rates increase as temperature increases)

Humidity (easier to transpire in dry air)

Air movement (increase air movement > more transpire
