AICE EM: Hydrosphere Key Content 1

2. The Global & Local Storage and Flow of Water
The main storage zones of water and the percentages of water held in each.
The natural flows and stores within both the global and local (drainage basin) cycles.
The global system includes the transfer between ocean/seas, atmosphere and land; it should refer to the conditions under which the volume of solid, liquid, and gaseous water will change.
The local water cycle includes evaporation, precipitation, interception, runoff, infiltration, and ground water.
Ground water stores are to include the features of natural aquifers: confined, unconfined and perched.

Can you give examples?
Solubility
Dissolves polar substances
Cohesion

Natural capital: groundwater system. An unconfined aquifer is an aquifer with a permeable water table. A confined aquifer is bounded above and below by less permeable beds of rock, and its water is confined under pressure. Some aquifers are replenished by precipitation; others are not.
