Drainage basin hydrological cycle

Question 1

Drainage basin

Answer 1

The area of land which drains water into a river, including all its tributaries

Question 2

Watershed

Answer 2

Borderlines of drainage basins

Often found in mountainous regions

Question 3

Drainage basin hydrological cycle

Answer 3

The movement of water in a drainage basin

Question 4

Global vs drainage basin hydrological cycles

Answer 4

Local is an open system

Global is a closed system

Question 5

Precipitation

Answer 5

Water falling from clouds in the atmosphere

Question 6

Surface runoff

Answer 6

The movement of water over the surface of the ground to the river

Question 7

Infilration

Answer 7

The process where water enters the soil

Question 8

Surface storage

Answer 8

Precipitation retained at surface level

I.e. puddles

Question 9

Interception

Answer 9

Water trapped on vegetation so it can’t go into stores or flows

Question 10

Transpiration

Answer 10

Loss of water from leaf stomata

Question 11

Channel flow

Answer 11

Water flowing in a river

Groundwater storage

Answer 13

Water stored in permeable rocks below the surface

Question 14

Soil water

Answer 14

Water stored in the soil after infiltration

Question 15

Evaporation

Answer 15

When water changes from a liquid to a gas and escapes to the atmosphere
