1

Water is considered to exist in a ____ system

closed

2

Evaporation

Net movement of free water molecules away from a west surface into air that is less than saturated.

3

Transpiration

Water moves into the atmosphere from land environments, including from the soil into plant roots and passing through their leaves to the air in a process called transpiration

4

Evapotranspiration

Evaporation and transpiration from Earth's land surfaces together

5

Interception

when precipitation strikes plants or ground cover rather than the ground.

6

Two basic pathways for precipitation reaching Earth's surface

Flows Overland


Soaks into soil

7

Principal pathways for precipitation

Flows Overland

Soaks into soil

Interception

Through-fall

Collection

Transpiration + Evaporation

8

Principal pathways for precipitation

Flows Overland

Soaks into soil (infiltration and Percolation)

Interception

Through-fall

Collection

Stemflow

Transpiration + Evaporation

9

Infiltration

the movement of water from the ground surface into a soil or into a porous rock or sediment

10

Percolation

The downward movement ???

11

Infiltration capacity determines...

the amount of water that can flow downward below Earth's surface

12

Infiltration capacity criteriobn

Intensity and duration of rainfall??

13

Water Budget

derived from measuring the input of precipitation and its distribution and the outputs of evapotranspiration and surface runoff.

also includes stored moisture.

14

Water Demand

Potential evapotranspiration (PE).

The amount of water that would evapotranspire under optimum moisture conditions ...????????

15

Evapotranspiration

an actual expenditure of water to the atmosphere
