Biogeochemical Cycles

Biogeochemcial Cycles

They ensure that essential nutrients are reused

Water Cycle

known as the hydrological cycle also, the continous movement of xxxxx on, above and below the surface of the earth

Evaporation

the process where liquid turns into gas, the sun heats the water, causing surface molecules to escape as water vapor into the atmosphere

factors that affect evaporation

1.High Temp
2.Wind Speed
3.Large Water Surface

Condensation

the process where gas turns into liquid, when water vapor cools and turn into liquid droplets, forming clouds

High Cloud

this type of cloud is composed of mostly ice crystals

Middle Cloud

type of cloud that is composed of both ice crystals and water droplets

Low Cloud

this type of cloud is composed of water droplets

Precipitation

liquid process, water falls in solid or liquid state. ex. hail, snow, rain

collection

when precipitation gathers in rivers, lakes,oceans and underground aquifers, replenish freashwater sources

aquifers

storage of underground water

Evaporation, Transporation, Condensation, Precipitation and Collection

what is the order of the water cycle

Carbon Cycle

continous exchange of carbon, plays a role in sustaining life and maintaining ecological balance

Transpiration

liquid to gas, water from plants turn into

hydrological cycle

also known has the water cycle
