Water and Tropical Forests EOY Revision

____________________________ is a sequence of processes that occur to ensure that water is naturally replenished on the Earth.

• Transpiration

• Hydrological cycle

• Evaporation

• Condensation

In the hydrological cycle, plants give out water vapour through the process of _______________________.

• evaporation

• condensation

• transpiration

• precipitation

In the hydrological cycle, some of the water that falls to the ground may seep into the soil through the process of _______________________.

• ground water

• precipitation

• infiltration

• surface runoff

In the hydrological cycle, the rest of the water (not absorbed into the ground) flows over the earth’s surface, down hills and mountains into rivers, lakes and seas. This is known as ____________________________.

• surface runoff

• subsurface flow

• infiltration

• transpiration

Which of the following correctly represents the water budget?

• Net = (surface runoff, evaporation, transpiration) + precipitation

• Net = (surface runoff, evaporation, transpiration) - precipitation

• Net = (precipitation, surface runoff) - (evaporation, transpiration)

• Net = precipitation - (surface runoff, evaporation, transpiration)

Water deficit occurs when ______________________________.

• Input = output

• Input > output

• Output > Input

• Input + output

____________________ are caused by exceptionally heavy rainfall over a short period of time

• Coastal floods

• Flash floods

• River floods

• Storm surges

_________________________ are caused by sustained heavy rainfall, or meltwater produced when snow and ice start to melt in the spring season.

• Flash floods

• River floods

• Coastal floods

• Storm surges
