• The water cycle has no starting The water cycle has no starting or ending point.or ending point.

• The sun provides energy The sun provides energy which makes the water cyclewhich makes the water cycle

• There are many processes There are many processes

that make up the water cyclethat make up the water cycle.

PrecipitationPrecipitation• Precipitation is Precipitation is

when condensed when condensed water falls to the water falls to the earth in the form of earth in the form of rain, hail, sleet, or rain, hail, sleet, or snow.snow.

• Precipitation is Precipitation is responsible for responsible for depositing most of depositing most of the fresh water in the fresh water in the planetthe planet

Evaporation

•Evaporation is Evaporation is the process in the process in which a liquid which a liquid such as water such as water becomes a becomes a gas.gas.

Condensation

• Solar Energy drives Solar Energy drives evaporationevaporation

• Condensation is the process in Condensation is the process in which a gas becomes a liquid,which a gas becomes a liquid,

• Water condensing in the Water condensing in the atmosphere creates clouds, atmosphere creates clouds, mist, and fog.mist, and fog.

Runoff• Runoff occurs Runoff occurs

when excess water when excess water from snow or rain from snow or rain flows over land and flows over land and empties into water.empties into water.

• Effects of a runoff Effects of a runoff are water pollution, are water pollution, soil erosion, soil erosion, flooding, and flooding, and agricultural issues.agricultural issues.

Sublimation

• Sublimation is Sublimation is when a when a compound or compound or element element becomes a becomes a solid or gas solid or gas forgoing the forgoing the liquid state.liquid state.

Interception

• Interception occurs when precipitation Interception occurs when precipitation does not reach the soil because leaves and does not reach the soil because leaves and branches prevent the water from reaching branches prevent the water from reaching the ground. the ground.

• It occurs in the canopy and forest ground It occurs in the canopy and forest ground litter.litter.

Advection

• Advection is when water in solid, Advection is when water in solid, liquid, and vaporous states moves liquid, and vaporous states moves through the atmosphere.through the atmosphere.

• Advection is vital because Advection is vital because evaporated water could not evaporated water could not precipitate over land without itprecipitate over land without it

Infiltration• It occurs when water on It occurs when water on

the ground enters soil.the ground enters soil.• Infiltration rate is a Infiltration rate is a

measure of the rate at measure of the rate at which soil absorbs which soil absorbs rainfall. It’s important rainfall. It’s important because if the because if the precipitation exceeds precipitation exceeds the infiltration rate, the infiltration rate, runoff will occurrunoff will occur

Subsurface FlowSubsurface Flow

• Subsurface flow is the flow of Subsurface flow is the flow of water underground. Subsurface water underground. Subsurface water returns to the surface via water returns to the surface via springs or aquifers.springs or aquifers.

• Subsurface water returns to the Subsurface water returns to the surface at a lower elevation than it surface at a lower elevation than it entered the ground due to gravityentered the ground due to gravity

Snowmelt• Surface runoff produced

my melting snow.• Rapid snowmelt can be

dangerous by creating floods and many hazards.

• Predicting snowmelt runoff is important in designing water control projects.

WATER IS FUN!!!
