The Carbon Cycle/ Climate Change

Question 1

List some uses of co2

Answer 1

• makes earth warm enough for life

- plants are able to make their food

Question 2

Word equation for respiration

Answer 2

Glucose + energy -> carbon dioxide + water + energy

Question 3

Word equation for photosynthesis

Answer 3

Carbon dioxide + water ->. Oxygen + glucose

Question 4

Define combustion

Answer 4

Burning

Question 5

Define carbon cycle

Answer 5

Shows how carbon leaves and enters the atmosphere

How it is stored

Question 6

List some carbon stores

Answer 6

Atmosphere
Ocean
Soil
Rocks. (Sedimentary)
Animals,plants
Fossil fuels

Question 7

List some process that transfer carbon into the atmosphere

Answer 7

Respiration
Combustion of fossil fuels
Deforestation. (Burning or limits photosynthesis)

Question 8

Process that take out carbon from the atmosphere

Answer 8

Photosynthesis
Dissolving into oceans
Decay in absence of oxygen

Question 9

State one route of carbon transfer

Answer 9

-Co2 in the atmosphere
-plants take in this for photosynthesis
-animal eats plant
-animal dies and body decomposes into soil
-

Question 10

Define climate change

Answer 10

A long term change in weather patterns

Question 11

Deforestation definition

Answer 11

The cutting down or burning of trees in forests

Question 12

Radiation definition

Answer 12

Transfer of energy produced by earth as a wave

Question 13

Define green house effect

Answer 13

The reabsorbing of energy by gases in the atmosphere

Question 14

Define greenhouse gases

Answer 14

A gas that reabsorbs radiation

Eg co2,methane, nitrous oxide

Question 15

Define global warming

Answer 15

The increase of the earths average air temperature

Question 16

How has the increase of green hous gases effected climate change

Answer 16

More ghg have reabsorbed radiation warming the Earth at a quicker pace

Question 17

Describe the stages in of the greenhouse effect

Answer 17

• sun heats earth
• some radiation produced by earth escapes into space
• the greenhouse gases layer traps that radiation
• leading to the earth having more heat/energy than needed = global warming

Question 18

List some impacts of global warming

Answer 18

• Polar ice melting = sea levels rising= floods
• droughts= less crops= financial struggle for poorer countries
• by 2100 mean air temp should increase by 5. C
• species extinctions
