WATER VAPOR
what can cause water vapor?
the evaporation or boiling of liquid water or from the sublimation of ice
What factors affect transpiration?
What are the problems with runoff?
may kill aquatic organisms or impair their health, growth or ability to reproduce.
Are liquids compressible?
In machine design, for example, pumps, water turbines, etc., liquids are usually treated as incompressible fluids.
What is the biggest threat to groundwater?
Stressors that affect ground water condition include application of pesticides and fertilizers to the land, waste from livestock and other animals, landfills, mining operations, and unintentional releases such as chemical spills or leaks from storage tanks
How does water vapor affect us?
causes roughly half of the warming of the planet.
What will cause the fastest transpiration
Plants transpire more rapidly in the light than in the dark.
How to prevent runoff?
What volume do liquids have?
Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Will groundwater run out?
US in danger of running out of groundwater from overuse: NYT. American groundwater has been severely depleted in recent decades, with 40 percent of more than 85,000 wells hitting all-time lows in the past decade and rainwater failing to replace the losses, according to an analysis by The New York Times.
Is water vapor good or bad?
It's the most important greenhouse gas in our climate system, because of its relatively high concentrations
What slows down transpiration?
As the relative humidity of the air surrounding the plant increases, the transpiration rate decreases.
What slows down runoff?
Adding organic matter or compost to the soil reduces soil density and improves soil structure.
Why do we measure liquid?
the liquid measurement units are commercially used for the trade purpose of commodities such as petrol, water, oil, and others.
Why is groundwater unsafe?
Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use.
What is water vapor made of
water molecules
What are 3 examples of transpiration?
How can farmers reduce runoff?
Farmers can leave the soil surface undisturbed from harvest to planting (using conservation practices such as no-till or conservation tillage) to reduce runoff, plant cover crops to uptake residual nutrients, and/or maintain vegetated buffer strips around fields and streams to intercept runoff
Does liquid have shape?
In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
Groundwater tends to be harder than surface water and can range to greater than 1000 mg/L.
How can water vapour change back to water?
when water vapor in the air loses energy (cools).
Is transpiration a sun or gravity?
Gravity causes water to flow downward on land. I
What causes land runoff?
Stormwater runoff is naturally occurring water originating as rain, melting snow, or groundwater that is not able to seep into the ground but instead travels across the land surface.
Do liquids have mass?
Everything that has a physical presence has mass, including liquids and gasses.
What is the pH of groundwater?
about 6.0 to 8.5
