water and carbok 1 Flashcards
Input water cycle
rainfall
input carbon cycle
rainfall with dissolved CO2 in it
output water cycle
River flowing into sea - moving from one system to another
output carbon cycle
Carbon leaving the woodland
energy water cycle
Linked to the changes in the state of water (frozen to water, water to frozen, water to water vapour, water vapour to water)
energy carbon cycle
Photosynthesis - chlorophyll in leaves uses sun’s energy
water cycle stores
Lakes
Soil - puddles on side of river
Trees
carbon cycle stores
Trees
Soil
water cycle flows
Vegetation - uptake of water from roots
The flow of rivers through system and tributaries
Evaporation
carbon cycle flows
Water moving dissolved CO2 out - river
Absorption
Roots take up carbon from water
Burning
positive feedback example water cycle
Increasing temperatures, melting ice glaciers, extra water frozen stored up in mountains comes down mountain and through river basin into sea, sea-level rise, destabilises ice shelves in Antarctica, they melt and sea level rises
positive feedback example carbon cycle
Permafrost accounts for nearly half of all organic carbon stored within the planet’s soil. As long as this organic matter remains frozen, it will stay trapped in the permafrost.
However, if it thaws, microbes will begin to eat the material, causing it to decay and releasing carbon dioxide and methane into the atmosphere.Greenhouse gases are released, intensify global climate change. Hotter temperatures thaw more frozen organic matter.
negative feedback example water cycle
Increase in temperatures, increase in evaporation, leads to more cloud cover, clouds reflect radiation from sun away from earth resulting in a cooling effect of surface temperatures, returning to a dynamic equilibrium, neutralising initial increase in temperature
negative feedback example carbon cycle
Increased temperatures encourage plant growth and there is more absorption of carbon dioxide meaning less greenhouse gases are being released into the atmosphere, slowing down rising temperatures
where can you find a dynamic equilibrium in the water cycle?
Unaffected drainage basins in remote areas where there has been no human activity
