Water Cycle
Evaporation
Condensation
Precipitation
Transpiration
What do they use to build roads?
Cement/tar
What is a flood?
When water covers land that is normally dry.
What does GAB stand for?
Great Artesian Basin
What is ground water?
The types of precipitation
Rain
Hail
Sleet
Snow
Name two hard surfaces commonly found in urban areas.
Roads, footpaths, concrete, car parks, roofs, etc.
Name one cause of flooding.
Heavy rainfall, overflowing rivers, storm surge, blocked drainage, etc
Is the Great Artesian Basin mainly surface water or groundwater?
Groundwater
What percentage of the worlds water is freshwater?
3%
What is the process where liquid water changes into water vapour because of heat?
A city replaces a grassy area with a large car park. What happens to infiltration?
It decreases because the hard surface stops or reduces water entering the soil.
Why can heavy rainfall cause rivers to rise?
Rain adds water to the river and its catchment. Runoff can carry large amounts of water into the river.
What is an aquifer?
A layer of rock or sediment that can store and transmit groundwater.
What is run-off?
Water that flows down mountains, streams, streets or across lands.
Explain how the Sun helps drive the water cycle.
The Sun provides heat energy, causing water to evaporate. This water vapour rises, cools and helps form clouds, continuing the water cycle.
Why might removing trees affect the water cycle?
Trees take up water through their roots and release water vapour through transpiration. Fewer trees can mean less transpiration and more runoff.
It means the river is following a path or moving
Where does water in the Great Artesian Basin mainly come from?
Recharge zones!
Why is capping unused bores a good strategy?
Because the water cannot be wasted and the pressure used to pump it out can be dispersed back into the GAB to replenish natural water springs or sources etc.
Explain how the Sun helps drive the water cycle.
The Sun provides heat energy, causing water to evaporate. This water vapour rises, cools and helps form clouds, continuing the water cycle.
What happens due to urbanisation with connection to the water cycle.
What are the three types of flooding?
flash flooding, fast-onset flooding, and slow-onset flooding.
How is the GAB used by three different groups of people, give an example for each use to each group of people.
....
A farmer pumps groundwater from the Great Artesian Basin faster than it is naturally replaced. What problem could this cause?
The groundwater supply can decrease because water is being removed faster than the aquifer is recharged.
