Hydrological Cycle

Question 1

Hydrological system

Answer 1

A sequence of processes that occur to ensure that water is naturally replenished on teh Earth. This is a global circulation of water- a giant closed system. This means that there is a a fixed mount of water in teh system because water can neither enter or leaves the earth and its atmosphere

Question 2

Precipitation

Answer 2

Any moisture that falls from the sky

Question 3

Infiltration

Answer 3

When water travels form teh surface of teh earth into the ground beneath

Question 4

Surface run-off

Answer 4

When water travels across teh surface of teh earth

Question 5

Channel flow

Answer 5

Water that’s travelling in river or streams.

Question 6

Through Fall

Answer 6

Water that passes directly through a canopy or is initially intercepted by above ground vegetative surfaces and subsequently drips from the canopy

Question 7

Leaf Drip

Answer 7

Intercepted water dripping off vegetation to ground

Question 8

Stem flow

Answer 8

When intercepted water drains from outlying leaves and branches and is channeled to teh stems and trunks of the vegetation

Question 9

Percolation

Answer 9

When water travels deeper into teh ground, from unsaturated ground into saturated ground.

Question 10

Groundwater-flow

Answer 10

Teh movement of water through saturated ground, known as aquifer.

Question 11

Through-flow

Answer 11

Lateral movement of water through unsaturated ground, Close to teh land surface

Question 12

Interception

Answer 12

When an object stops precipitation from reaching beneath the ground

Question 13

Vegetation storage

Answer 13

All moisture stores in vegetation

Question 14

Surface storage

Answer 14

Any water that is held on the surface of the earth. Some surface stores may be temporary

Question 15

Soil moisture

Answer 15

Water that is stores below the surface in unsaturated ground

Question 16

Groundwater storage

Answer 16

Water that is stored in saturated ground

Question 17

Channel storage

Answer 17

Teh volume of water contained within teh banks of a river will operate as a water store between the initial input and ultimate output

Question 18

Evaporation

Answer 18

Liquid water from surface stores and rivers turning into water vapour

Question 19

Transpiration

Answer 19

Liquid water evaporating from vegetation

Question 20

River runoff/discharge

Answer 20

Most rivers enetrs teh sea and discharge teh river’s flow into the sea.
