Carbon and water cycle Flashcards
what is the def of dynamic eqaulibruim
when the inputs and outputs tend towards a natural state of balance
name 3 physical factors that effect the run off and water cycle and how that relates to a hydrograph
slope steepness - the stepper the slope , faster the runoff ,shorter the lag time.
Vegation - the more Vegation more interception
smaller peak discharge and longer lag time
Rock soil type - if soil is impermable , less infiltration , more runoff,
higher peak discharge
smaller lag time
Name 3 human factors that affect run off and water cycle
Growth of urban Areas - Construction creates lots of impeccable layers
Reduce infiltration
Increase run off and more flooding
Deforstation - Will reduce the amount of water intercepted by negation will decrease with run off:shorter lag time ; higher peak flow.
Agriculture - Livestock compact soil decreasing infiltration and increasing run off
what are the 4 stores of water on Earth
Oceanic water
terristal water- water found in biological ecosystems
Cryospheric water
Atmospheric water
Give me some facts about Oceanic and Atmospheric water
Oceanic is the largest store of water
- 97 % of all water is in the oceans
Atmosperhic is
- 04% of world total fresh water
- 001 of total water
What is teristal water
This consist of ground water, soil, moisture, lakes, wetlands and rivers.
how does the flow of evaporation vary over time and space
Time:more solar radiation in countries during summer, meaning more Evaporation.
Space; location, some areas have more solar radiation
hot and dry
Evaporation will be high
how time and space changes Condensation overtime:
time: Temperatures fall eat night due to heat being tossed in space meaning more condensation
Space; Some areas are generally going to be colder causing rainfall - condensation nuclei.
What is a closed system
Matter and energy cant enter/leave the system
what is an input
where matter of energy is added to the system
what is an output j
where matter or energy leaves the system
what is a flow
when matter energy moves from 1 store to another
Give an example of Negative feedback
- Large amount of C02 emitted to the environment
- C02 in the atmosphere increases
- Extra C02 causes plants to increase growth
- More photo synthesis
- Amount of C02 in the atmosphere decreases
what is a boundary
the limit of the sesystem
what is better for the envirmonet
negative feedback
