GEOGRAPHY Y07 T1 Flashcards
Explain the Water Cycle
evaporation, condensation, precipitation, surface run off, infiltration and
transpiration.
What is precipitation?
water droplets increase in size and weight and fall onto the earth’s surface.
What is condensation?
when water vapor cools, it condenses to form cloud and fog.
Think about precipitation: Give FOUR examples of it.
Rain, Hail, snow and sleet.
What is transpiration? Explain why this is important in the water cycle.
Plants transpire water from the soil into the atmosphere as water vapor.
Explain the difference between a renewable and a non-renewable resource. Give an example of EACH.
Renewable= Something you can regrow E.G wood
Non-Renewable= Once it has been used you can’t get it back E.G Oil
Explain what infiltration is.
when the water moves into the ground from the surface and soaks between soil and rock layers.
What is a water catchment? Where is water first “caught”?
A catchment is an area where water is collected by the natural landscape.
Explain what an environmental resource is?
any material, service, or information from the environment that is valuable to society. E.G land, water
Where is our freshwater stored? Be specific and give examples.
Wivenhoe and somerset dams are located upstream of the Brisbane River.
What is evaporation?
the process of turning from liquid into vapour.
What is a water shed?
A watershed is an area of land that drains water into a specific waterbody.
What does ‘run off’ refer to in the water cycle?
When there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds
Why is water not distributed evenly around the world?
Climate change is causing more frequent and severe flooding and droughts, intensifying the water stress in some regions.
What is irrigation in farming? Explain how this is connected to crops.
large scale industrial watering systems for extensive farm crops
What is irrigation in farming? Explain how this is connected to crops.
water crops by bringing in water from pipes, canals, sprinklers, or other man-made means, rather than relying on rainfall alone.
Name THREE ways water connects people to places and therefore influences where people choose to settle.
It bonds mountain tops to river beds, connects cities upstream with communities along the coast, and transports the external world into our bodies. Water flows through us, protecting organs and delivering essential nutrients to cell.
Why do people in some countries have less access to water than others?
Sharp geographic, sociocultural and economic inequalities
Explain why it is important to look after renewable resources.
Renewable resources are capable of regenerating after harvesting, so their use can potentially be sustained forever.
Give THREE examples of a continuous resource.
waves, sun, tide and wind power.
What is infiltration? Where does it belong in the ‘flow’ of the water cycle?
when water on the grounds surface soaks into the earth’s soil. Infiltration happens after rainfall runs off the surface of land then saturates into the soil.
What percentage of water on earth is saltwater? Is it an available or potential resource? Explain your thinking!
97.5% of earth’s water is saltwater. Yes, saltwater can be used as a resource for salt, or you can take the salt out and become fresh water.
What is surface water? Give TWO examples.
Identify two ways water can negatively affect a place.
What are floodplains? Explain why this is important for crops.
List THREE main uses of water.
List THREE main uses of water.
