Water Cycle, How It Influences Our World, Processes Of Change

Question 1

Why is the water cycle important

Answer 1

• water vapour is vital to all climates on earth
• water gives life to all living things
• vast majority of water comes from ice

Question 2

What is flow/transfer

Answer 2

linkage between one store and another that involves energy e.g. river to ocean

Question 3

What is flow/transfer

Answer 3

linkage between one store and another that involves energy e.g. river to ocean

Question 4

What is input

Answer 4

the addition of mass to a system

Question 5

What is store/component

Answer 5

part of the water cycle where energy mass is stored e.g glacier

Question 6

what is a system

Answer 6

a set of components working together (water cycle)

Question 7

What percentage of all water on earth is freshwater

Answer 7

3%

Question 8

What is an isolated system

Answer 8

no interactions with anything outside the systems boundaries
- Swamp
- Pond

Question 9

What is a closed system

Answer 9

have transfers in and beyond but no transfers of matter
- Canal

Question 10

what is an open system

Answer 10

where matter and energy can be transferred from the system into the surrounding environment

Question 11

Where can you find biospheric water

Answer 11

in plants

Question 12

Where can you find Atmospheric water

Answer 12

The clouds

Question 13

where can you find cryospheric water

Answer 13

Ice

Question 14

Where can you find terrestrial water

Answer 14

Rivers and lakes

Question 15

where can you find groundwater

Answer 15

underground

Question 16

What is the water cycle

Answer 16

The water cycle is the circulation of water around the word between the oceans, Iand and atmosphere

Question 17

What can affect the magnitude of water held in a store

Answer 17

Seasonal change
e. g. melting and freezing of ice caps

Question 18

Process of the water cycle

Answer 18

• water is evaporated from a body of water
• it cools and condenses into clouds
• the clouds then precipitate as rain or snow
• the water then makes it way back to the sea as surface run off

Question 19

what is the atmosphere

Answer 19

The gases that surrounds our planet

Question 20

what are clouds

Answer 20

a mass of condensed water vapor that floats in the atmosphere

Question 21

what is condensation

Answer 21

The process of gas cooling down into liquids

Question 22

what is evaporation

Answer 22

The process of livid heating up into gas

Question 23

What is freshwater

Answer 23

water that isn’t salty

Question 24

what is ground water

Answer 24

water that has soaked into the ground and is stored there

Question 25

what is polution

Answer 25

harmful Substances that contaminate water and the environment

Question 26

What is precipitation

Answer 26

water falling from the clouds to the ground, river and ocean

Question 27

what is water vapour

Answer 27

water in the form of gas

Question 28

What does a body of water need to be in equilibrium

Answer 28

steady input and steady output

Question 29

What can too much water cause

Answer 29

flooding downstream

Question 30

what can too little water cause

Answer 30

Drought downstream

Question 31

Name 3 Naturally occurring factors that affect water change

Answer 31

Extreme weather wildfires seasonal variation

Question 32

Why does extreme weather cause water change

Answer 32

Tropical storm bring large amounts of water

Question 33

Why do wildfires cause waterchange

Answer 33

The burning vegetation releases water that then condenses and the clouds move away from the area causing drought

Question 34

Why does seasonal variation cause water variation

Answer 34

more rainfall can occur in winter and less in summer

Question 35

Name 4 Human occuring factors that affect water change

Answer 35

Aagriculture Desertification Deforestation urbanisation

Question 36

How does Agriculture affect water change

Answer 36

Farmers use excessive amounts of crops or not enough so local rivers are not in equilibrium

Question 37

How does desertification affect the water cycle

Answer 37

This can occur when humans have restricted the natural water cycle

Question 38

How can deforestation affect the water cycle

Answer 38

Trees hold large amounts of water so when they get cut down we loose large amounts of water storage

Question 39

How does urbanisation affect water change

Answer 39

It creates impermeable surfaces on large scale meaning no water can be absorbed into the groundwater stores
