, 1. Vocabulary:
Condensation:
◼ The cooling of a gas so that it changes into a liquid, for instance as water vapour cools, it
condenses to become water droplets, which, when heavy enough, fall as rain.
Confluence:
◼ Where two rivers meet and join to form one larger river.
Delta:
◼ A build up of sediment at the point where a river meets a sea or lake, due to the water
velocity slowing and the river having less energy to carry the sediment.
Drainage Basin:
◼ The area of land drained by a river and its tributaries.
Estuary:
◼ The point at which a river begins to meet the sea. The river will be tidal, meaning that it
will have both salt water and fresh water in it.
, Evaporation:
◼ Water that is warmed, usually by the sun, so that it changes into a
gas (water vapour).
Evapo-transpiration:
◼ The combination of evaporation and transpiration.
Fluvial:
◼ relating to a river, from the Latin for water.
Hydrology:
◼ The study of water
Infiltration:
◼ The downward movement of water that seeps into the soil or a
porous rock.
, Mouth:
◼ The end of the river, where it meets the sea, or a lake.
Overland Flow:
◼ When water flows over the surface of the ground. This occurs for a
number of reasons: the soil may be saturated and therefore be
unable to absorb any more water; the underlying rock may be
impermeable or the ground may be frozen.
Percolation:
◼ The movement of water through the soil or underlying porous
rock. This water collects as groundwater.
Precipitation:
◼ Waterfalling to Earth in any form: e.g. rain, sleet, hail, snow, and
dew, all are encompassed by the term precipitation.
