Water 1
When solid ice gains thermal energy, it changes state from solid ice to liquid water in a process called
Melting
This is water found in rivers, lakes, and streams.
Surface water
95 % of the worlds water is stored in?
Oceans
This is the first step in most water treatment plants, where large debris like leaves and branches are removed from the water.
screening or filtration
What is the main source of energy for the water cycle?
The Sun
This occurs when water vapour changes state directly from a gas to a solid
Deposition
The area of land that drains into a particular river or lake is called this.
Watershed
Changing from a liquid to a solid is called?
Freezing
This process, commonly used in drinking water treatment plants, uses ultraviolet light or chlorine to kill harmful microorganisms in the water.
Disinfection
In this stage of the water cycle, water becomes a gas called water vapor.
Evaporation
When liquid water absorbs enough thermal energy, it becomes a gas. This is called.
Evaporation
Only about this percentage of the Earth's water is freshwater.
3%
This is a liquid or solid falling from the atmosphere
Precipitation
Water that soaks into the ground and is stored in spaces in soil and rock is called this.
Groundwater
Describe one way to conserve water
Shorter showers
Use dishwasher
Water lawn when its cooler outside
Turn off tap when brushing teeth
When water vapour loses thermal energy and becomes liquid water, this has occurred.
Condensation
This large Canadian freshwater lake system borders Ontario.
The Great Lakes (HOMES)
An example of condensation
A glass of ice-cold soda sitting outside on a hot summer day. The glass will form water droplets on the outside of the glass.
Dew on the grass on a cool summer morning is another example.
These are structures drilled into the ground to bring up groundwater.
Wells
Using too many chemicals on lawns or farms can cause this kind of pollution in groundwater.
Contamination
This change, directly from a solid to a gas without becoming a liquid, is called
Sublimation.
This term describes water that collects underground in the spaces between soil and rock.
Groundwater
One example of THIS occurs high in the atmosphere where the temperature is very low. In these conditions, water vapour forms snow without becoming a liquid first.
Deposition
This term describes how humans can protect and manage water resources wisely.
Water conservation?
After screening, water is often treated with chemicals like aluminum sulfate to help particles stick together and form clumps in a process called this.
flocculation or floc
