Hydrosphere

Deforestation, agriculture, urban development, global climate change

Can create new habitats but lose old one Prevent migration of some species River regime downstream of dams Sedimentation Microclimates

the excessive richness of nutrients which can cause excessive growth of plants

precipitation that doesn’t reach the soil but instead is intercepted by leaves and branches

precipitation/water soaks into sub-surface and moves through cracks and pore spaces

the process where rainfall seeps underground

precipitation that did not get infiltrates or evaporated

the upper level of an underground surface in which the soil or rocks are permanently saturated with water

water held underground in the soil, pores and rocks

taking water from natural sources for a use

running water through a grill to remove more less dense solids

putting air into the water to prevent anaerobic respiration

chemical (allum) is added to create a neutral bond to allow particle (clay) to bond to it

Filtering the water through chalk or sand to remove any last impurities

Regulate river flow Keep habitats

fertilise floodplains, counteract erosion

a large body of water may change the local climate

a large body of rock that holds water which is exploited as a resource

a measure of space in rocks that can hold water

how easy it is for fluids to flow through the rocks

rock below must be impermeable to prevent escape of water

Where the water into the aquifer is greater than that leaving it

Changes in surface hydrology Ecological impacts Saltwater incursions Subsidence Reduced supplies

GRACE satellites - their orbit is affected by gravity which is influenced by water mass
