Parts of the Water Cycle
What is the Precipiatation stage?
When water droplets or ice crystals become to heavy in clouds and fall to the Earth's surface in the form of rain, snow, sleet, or hail.
Does the total amount of water on Earth ever change?
No, the water on Earth is at a fixed amount in one of the 3 forms during different stages of the water cycle.
How does the water cycle support ecosystems?
1. It distributes water throughout various ecosystems across the globe.
2. Water causes many geological processes the shape the Earth.
3. Minerals and nutrients flow in the water across the Earth.
What is the process called when water vapor turns back into liquid water?
Condensation
Is the evaporatation stage when water transforms into water vapor?
Yes
What is the runoff stage?
When water flows across the land evantually reaching rivers, lakes, and oceans.
How much water is used per day by Canadians?
Canadians use 343 gallons per day
How does the water cycle sustain life?
1. It adds freshwater to rivers, lakes, and groundwater for consumption, agriculture, and other processes.
2. The water cycle supports ecosystems by providing freshwater for all living organisms that require it to survive.
3. It provides water for significant biological processes in all living organisms.
What is evaporation and how does it contribute to the water cycle?
The process where liquid water turns into vapor due to heat energy.
Does the water cycle involve all 3 spheres (Lithosphere, atmosphere, and hydrosphere)?
Yes
What is the final stage of the water cycle?
Infiltration
Water absorbed into the ground which replenishing groundwater supplies
What percent water is salt vs fresh?
Approximately 97% of the Earth's water is saltwater, found in oceans, while the remaining 3% is freshwater
How does the water cycle regulate climate?
1. The water cycle affects weather patterns which effects the Earth's climate.
2. The water absorbs and releases heat during the cycle which effects the climate and temperature.
How much of Earth’s total freshwater is found in glaciers?
68%
Is metamorphism a stage in the water cycle?
No, it is the final stage in the rock cycle.
What causes the first stage whcih is the evaporation of water vapour?
Heat from the sun to warm the water into a gas (water vapour) and other atmospheric conditions
Does the water cycle ever stop?
No, the water cycle is continuous process.
How does the water cycle affects Earth's water supplY?
It cycles water to provide clean water and it naturally recycles to maintain Earth's water supplies.
Where does most of earth’s evaporation occur?
The oceans
Name one form of precipitation?
Rain
Snow
Sleet
Hail
Freezing Rain
etc
What are the 7 stages of the water cycle?
Evaporation
Transpiration
Condensation
Precipitation
Sublimation
Runoff
Infiltration
Over 60%+ of the human body is water
What are the 3 reaons why the water cycle important to Earth?
1. Sustaining life
2. Regulating climate
3. Supporting ecosystems
What 2 elements make up water?
Hydrogen and Oxygen
H20
Name one stage in the Water cycle?
Evaporation, Transpiration, Condensation, Precipitation, Sublimation, Runoff, Infiltration
