Water Properties
A real world example of cohesion.
What is water forming completely spherical droplets on a leaf?
The process of water turning into water vapor after being heated by the sun.
What is Evaporation?
The land that water flows across or under on its way to a river.
What is a River Basin?
A consequence that can occur in water bodies from fertilizer use on farms
What is Eutrophication?
Attraction between similar molecules.
What is cohesion?
A real world example of adhesion.
What is dew forming on grass, paint sticking to a wall, etc?
Water vapor turns into small water droplets and forms clouds.
An area where a freshwater river or stream meets the ocean.
What is an Estuary?
Long-term problems caused by over pumping groundwater.
What are: Dried up water bodies, ecosystem damage, infrastructure damage, introducing contaminants?
Attraction between different molecules.
What is Adhesion?
The reason ice floats on water.
What is lower density?
Water returns to the earth from the sky in forms of rain, snow, and hail.
An underground layer of water-bearing, permeable rock, gravel, sand, or silt that stores and transmits groundwater.
What is an Aquifer?
Human activities that negatively affect the water cycle.
What are: Deforestation, urbanization, pollution, fossil fuel use, and agricultural practices.
The uneven distribution of charge in a water molecule.
What is Polarity?
How capillary action helps move water through soil and plants.
Water collects on top of soil and drains into water bodies.
What is Run-off?
Vital ecosystem where water covers the soil during all or part of the year. Act as natural sponges for flood control and filtration.
What are Wetlands?
Ways deforestation or urbanization may increase flooding and erosion.
What are: Removing vegetation, covering soil with surfaces that prevent infiltration, destroying root systems that keep soil in place and absorb water.
The ability of a liquid to flow in narrow spaces, like thin tubes, without the help of external force like gravity.
What is Capillary Action?
An example of how one property of water supports life on earth.
What are: Specifc heat capacity: body temperature regulation, Adhesion: Water moving through plants' leaves and roots to hydrate them.
Why evaporation is considered a cooling process.
The movement of saline water into freshwater aquifers, primarily caused by over-pumping groundwater and sea-level rise.
What is Saltwater Intrusion?
Ways human development in a river basin can change the flow of water.
What are: Urbanization, dams, agriculture, destruction of vegetation and trees.
Over-enrichment of water by nutrients. Causes excessive algae growth, oxygen depletion, and destroys aquatic life
What is Eutrophication?
