Vocabulary
The measure of salt concentration in water.
How water is transferred into the air by plants
What is transpiration
When a gas turns to a solid
A slow moving mass of ice formed over hundreds of years as a result of snow accumulation
What is a glacier
List each of the changes in state of water in the water cycle.
What is melting, deposition, evaporation, condensation, freezing
A large covering of ice over an area of land
What is an ice cap
Occurs when thermal (heat) energy is applied to ice to convert ice into liquid water
What is melting
When a solid changes into a liquid.
The boiling & freezing point of water
What is 100 degrees Celcius and zero degrees Celsius
What role(s) does the Sun play in the water cycle?
Thermal energy from the sun causes evaporation, condensation, melting, and sublimation
An area of land where all water collects into the same place (e.g. a river)
What is a watershed
Occurs when thermal energy is applied to water in a liquid state
When a gas turns into a liquid
What is evaporation
Which of the following does not affect the water table level?
What is water quality
Why is Earth’s ice exclusively made of freshwater?
All frozen water on Earth is freshwater. This is because ocean water has a lower freezing point than freshwater. When ocean water freezes, the salt in the water does not freeze and is left behind.
The boundary between the unsaturated zone and the saturated zone.
What is a water table
Occurs when a gas loses thermal energy and changes to a liquid
What is condensation
When a solid turns into a gas
What is sublimation
Water with a high salt content is called...
What is brine water
Rural communities often use wells as a source of freshwater. What type of water is this?
What is groundwater
The zone beneath the water table that is saturated with water.
What is an aquifer
The last change of state that occurs when water changes from a liquid to a solid
What is freezing
When a liquid changes into a solid
What is freezing
Anything that is able to absorb thermal (heat) energy without becoming significantly warmer is called a...
What is a heat sink
What does it mean to use groundwater sustainably?
Sustainable groundwater use means to meet the needs of today, while ensuring future needs are met. There should be a plentiful supply of water for the future, in a clean, drinkable condition.
