Natural Water Cycle
Water that falls from the atmosphere as rain, hail, sleet or snow.
Precipitation
Water that travels across the surface of the ground instead of soaking into it
surface run-off
This type of graph is usually used to show change over a period of time
Line graph
An extended period of unusually low rainfall
Drought
A place where underground water is accessed by carefully digging into sand or soil.
Soakage/soak
The process in which liquid water is heated and changes into water vapour.
evaporation
These three common urban surfaces prevent water from infiltrating the soil (you must get at least 2 correct!)
roofs, roads and concrete paths
The horizontal axis on a graph is also called the...
Heavy rainfall across a dam’s catchment will usually cause the storage level to do this
increase or overflow
Name one way a soakage can be protected from contamination
covering it after use, keeping animals away, using clean containers, avoiding washing in it or preventing rubbish from entering
The process in which water vapour cools and changes into tiny liquid droplets, forming clouds
Condensation
Compared with natural areas, urban areas usually have more of this because water cannot soak through concrete
surface run-off
A map that uses different colours or shades to represent data in different areas
Choropleth map
The relationship or connection between two or more people, places or environments
interconnection
Structures made from stones or branches that guide fish into an area where they can be collected
fish traps
The process in which water soaks into the soil
infiltration
Compared with natural environments, urban environments usually have less of this process because the ground is covered by buildings and roads
infiltration
A map showing where something is located or concentrated across an area
spatial distribution map
Low dam levels may cause governments to introduce these rules limiting how people use water
Water restrictions
Knowledge of changes in weather, plants, animals and water throughout the year is called this
seasonal knowledge
The type of surface containing microscopic holes or channels that allow liquids, air, and bacteria to penetrate and absorb into it
Porous Surface
Urban development can cause streams to rise quickly during heavy rain, increasing the risk of this natural hazard
Flooding
This part of a map explains what its colours and symbols mean
legend or key
Fertilisers, oils, rubbish and chemicals carried into waterways by run-off cause this environmental problem
water pollution
Explain why First Nations seasonal calendars may be more useful than dividing the year into only summer, autumn, winter and spring
Example response: Local seasonal calendars are based on changes actually observed on Country, such as rainfall, winds, flowering plants and animal behaviour, which differ between places
