Question 7

Through flow

Answer 7

Movement of water downhill through the soil before entering river

Question 8

Surface storage

Answer 8

Where water is held in lakes

Question 9

Evaprotranspiration

Answer 9

Where water is evaporated from plants from the sun

Question 10

Interception

Answer 10

When water is caught, collected and stored by plants and vegetation

Question 11

Surface runoff

Answer 11

All water flow along surface of land which would eventually flow to river

Question 12

Infilltration

Answer 12

Water soaks from tops of ground into soil

Question 13

Precipitation

Answer 13

Water enters the system as hail, snow or rain

Question 14

Evaporation

Answer 14

When water leave the system and goes back to clouds from lakes/rivers

Question 15

Soil moisture storage

Answer 15

Where water gets kept or stored into the rock

Question 16

Percolation

Answer 16

Where water moves down from the soil into rocks

Question 17

River discharge

Answer 17

Water leaving the drainage system through the river

Question 18

What’s the difference between impermeable and permeable

Answer 18

Permeable allows water to pass through while impermeable doesn’t allow water to pass through

Question 19

Name the four types of erosion?

Answer 19

Attrition, solution, abrasion and hydraulic action

Question 20

Name the four types of transportation

Answer 20

Solution, saltation, traction and suspension

Question 21

What are the meaning of the four types of erosions

Answer 21

Attrition is rocks hitting each other,
Abrasion is rocks grinding against riverbed
Solution is beds and banks being dissolved in weaker acids in water
And hydraulic action is the force of the water being force into the banks and forcing air into crack causing it to widen therefore causing it collapse

Question 22

Meanings of the four types of transportation

Answer 22

Traction is larger fragments rolling along river bed
Saltation is large fragments bouncing along river bed
Suspension is smaller fragments carried in the follow of the river
Solution is dissolved minerals carried in river

Question 23

What is deposition

Answer 23

When river doesn’t have energy to transport the material and drop its off

Question 24

How is waterfall formed

Answer 24

Waterfall are found when hard rock is found over soft rock. As soft rock erodes away faster then hard a step develops and created a plunge pool. The force of hydraulic action and abrasion into the plunge oil causes undercutting of the hard rock and create and overhang. Overtime the overhang collapses and the waterfall retreats slowly upstream leaving behind a gorge

Question 25

Describe how a bed load changes with distance from source

Answer 25

Bedload size decreased changes the farther away you are from the source as it gets eroded down

Question 26

What’s the difference between impermeable and permeable

Answer 26

Impermeable means water cannot pass through but water can pass through permeable
