The Water Cycle !!

A Water Cycle !!

Not a Water Cycle!

Water Cycle Diagram – Instructions

Vapor = TransportationA. Transportation – moving H2OMovement of water from

one place to another

CondensationB. Evaporation & C. Condensation Liq => Gas Gas => Liq

Condensation – gaseous water or vapor changing into a liquid

Evaporation – liquid water changing into a gas or water vapor

D. Transpiration (Liq => Gas fm Tree leaves)

Water that moves through and evaporated from plants

PrecipitationE. Precipitation (falling H2O.)

Condensed water (rain, sleet, snow & hail) that falls to the ground

F. Surface Run off - on Oahu (moving H2O)

Water from rain, snow or ice melt that flows over the land surface

SUMMARY G. Infiltration & H. Percolation H2O penetrate soil surface H2O penetrate soil layers

I. Aquifer – H2O in sand & gravel layers

Storage of water underground. Underground water is called “groundwater”. This water is stored in the spaces between

sand & gravel.

Layers in soil show evidence of water

beneath the surface

J. Groundwater Flow (H2O flow underground)

Movement of groundwater

Man with a Dousing Rod In the early

1920’s“finding

water”Superstitious people

believed some had the “gift” to sense water

underground! Dowsers made a lot of

money for their ‘talents’.

Groundwater Quality issuesIf groundwater becomes contaminated, the polluted water flows

through the aquifer, spreading to other areas over time.

K. Return Flow – H2O flow on surface to lakes etc

Surface water flowing downhill to a larger water body

K. ‘Hidden’ Return flow from Human Use

Water flow / pumped to a larger water body after human use.

L. Accumulation – H2O liq. in large areas

L. Accumulation - H2O sol. in large areas

Gathering of large amounts of water over time in the form of liquid water, snow, or ice.

M. Sublimation Solid=>Gas (Dry Ice)Changing from a solid to a gas. Example, ice cubes in a freezer get

smaller as they “sublime” over time.

N. Deposition Gas => Solid

Water physically changing directly from a

gas to a solid.

O. Melting Solid => Liquid

a liquid.
