IGCSE GEOGRAPHY PAPER 1 EXAM GRADED A+
hydrological cycle - correct answer the movement of water
between the biosphere i.e. air, land and sea
open system - correct answer a system with inputs and
outputs/cross-boundary exchange e.g. river basin
closed system - correct answer a system with no inputs and outputs
e.g. the hydrological cycle
store - correct answer a place where water is temporarily received,
held and released
,IGCSE GEOGRAPHY PAPER 1 EXAM
transfer/flow - correct answer the movement of water between
different stores in the hydrological cycle
stores in the hydrological cycle - correct answer -atmosphere e.g.
water vapour or minute droplets in clouds
-land e.g. rivers, lakes and reservoirs as liquid, in bedrock as
liquid, ice in ice sheets or glaciers
-sea as liquid or as ice in icebergs at high-latitude
% of water from sea - correct answer 95%
evaporation - correct answer water converted from a liquid into
water vapour (gas)
transpiration - correct answer the emission of water vapour from
the leaves of plants into the atmosphere
evapotranspiration - correct answer the loss of moisture from the
ground by direct evaporation combined with transpiration from
plants
,IGCSE GEOGRAPHY PAPER 1 EXAM
condensation - correct answer the change in the atmosphere when
water vapour cools and becomes a liquid (water droplets in the
clouds)
precipitation - correct answer the transfer of water in any form e.g.
rain, hail, snow, from the atmosphere to the land or sea surface
overland flow - correct answer the movement of water on the
surface of the earth due to gravity, eventually entering a stream
or lake aka. run off
infiltration - correct answer the vertical movement of water from
the earth surface to the soil, as a result of gravity
percolation - correct answer the vertical movement of water
through the soil layer to the rock layer, as a result of gravity
throughflow - correct answer the transfer of water between the
ground surface and the top of the groundwater store (through
the soil) towards a river channel or stream
groundwater flow - correct answer the underground transfer of
water to rivers, lakes and seas in the rocks in the aquifer
, IGCSE GEOGRAPHY PAPER 1 EXAM
sometimes called base flow
aquifer - correct answer a body of permeable rock that can contain
or transmit groundwater
bedrock - correct answer rock that makes up Earth's crust; also the
solid rock layer beneath the soil
drainage basin - correct answer the area of land drained by a river
and its tributaries
also known as a river basin
source - correct answer where a river begins; usually In the
highlands or at a spring
tributary - correct answer a small stream or river that flows into a
larger river
confluence - correct answer the place where two rivers or
tributaries meet
