The Water Cycle Flashcards
(27 cards)
What does the spatial distribution mean?
The space being occupied by water
How much water covers the earths surface
67%
How much water is in ice caps
2.05%
How much of the water is freshwater
2.7%
How much of the water can be obtained by humans
0.7%
What is convection and what does it do in the water cycle
Convection is the process of transferring heat to heat gets transferred from the sun to water to create water vapor
What is the difference between transpiration and evaporation
Evaporation is when water turns into a gas called water vapor and transpiration is when water from plants’ stomata turns into ton water vapor.
What is precipitation
Any water falling from the sky naturally, includes rain, hail, sleet, and snow
What is the stomata
A stomata is the pores of a plant - where plants extract oxygen
What is fallen precipitation
When droplets are heavy enough to fall on the earth.
Where does fallen precipitation often go?
Fallen precipitation is often collected into bodies of water like rivers, ponds, the ocean.
Name the three types of rainfall
Orographic, Convectional and Frontal; Rainfall
Explain what the first type of rainfall does
When moist air is lifted to get over mountains and other heighted masses
Explain what the second type of rainfall does
Frontal rainfall is when cool air wedges itself underneath warm air making warm air rise.
Explain what the last type of rainfall does
Convection rainfall is when temperatures produce warm air making it rise and then rapidly condensing and making heavy rainfall.
Why is water important to Indigenous Aboriginals
Cultural and Spiritual Value as well as water management is a really big part of the culture of Aboriginals.
What importance does what have to nom indigenous Australians?
Income and Aesthetic value
What is a natural hazard
A hazard is an event that is a potential source of harm to human life, health, income or possessions, and the physical environment.
What are the two types of Natural hazards
Hydrological and Atmospherical hazards
What is the difference between the two natural hazards
Hydrological hazards are when there is a destructive change in the quality and distribution of water whereas an atmospherical hazard is a destructive change in the quality and distribution of air in the atmosphere
What is ground water
Water held in the soil
What is an aquifer
A rock that holds or transmits groundwater
Accumilation
to gather up little by little
Water Scarcity
When water becomes harder to physically access ad the supply and demand changes
