25
Why is Ice Important to the Earth climate?
- when Sunlight hits the ground its absorbed.
- But ice is white and the color white reflects sunlight.
- But ice only forms in cold Conditions.
26
Why is the northern hemisphere so important for regulating earths climate?
- There is More Land in the North pole Compared to the South Pole.
- Land Freezes more quickly than water so ice freezes on land more easily.

31
How long is the orbit cycle?
- 100,000 Year Cycle.
32
How much is the Earth Tilted?
- 23.5°
33
How does the Earth tilt affect its Climate?
-The More Earth Tilts the More sunlight is received in summer.
- Which Means more ice Melts and less light is reflected and creates a warmer earth.
34
How Long is The Tilt Cycle?
- 41,000 Year Cycle.
35
Write a Definition of Precession?
- Precession is the wobbles of the earth's axis.
36
How Does the Earth's Wobbles Affects Its Climate?
- The Wobble Dictates Which Direction the Northern Hemispheres is forcing in January.
37
How Long is The Wobble Cycle?
- 20,000 Year Cycle
38
Write a Definition of Sunspots and How Long is the sunspot cycle?
- A Sunspot is a Dark spot on the Sun.
- The Sunspot cycle is 11 years cycle.
39
What do Sunspots Cause?
- Sunspots Cause Temperature Change on Earth.
40
What Do Volcanoes release and how can it affect the earth's climate?
- Volcanoes release gas and ash.
- that gas and ash act as a cooling effect on the earth temperature.
41
Write a Definition of Volcanic Winter?
- A volcanic winter is a significant and prolonged cooling of Earth's climate caused by large-scale volcanic eruptions
42
Name 2 Ways Volcanic Eruption Cause Volcanic Winter?
- 1) Large Amounts of Volcanic Ash can stay in the atmosphere to block the sun.
- 2) Volcano Eruptions can emit sulfurous gas.
43
Write a Definition of The greenhouse Effect?
- The greenhouse Effect is a Natural Process where Greenhouse gases trap the energy from the sun inside the earth's atmosphere.
44
Name 4 Gases That mainly Trap Inside the Atmosphere and why is it called the greenhouse effect?
- Carbon Dioxide,Methane,Water Vapour and Nitrous Oxide Mainly Trap inside the Atmosphere.
- It Called the Greenhouse effect because in a Greenhouse The sun shines through the glass which heats up the air inside and then heat is then trapped in the greenhouse.
45
Write a Definition of Enhanced greenhouse Effect?
- Enhanced Greenhouse Effect is a Natural Process Where the earth's surface is heated by the greenhouse effect at a higher rate due to increased greenhouse gas emission from human activities.
46
List the 6 Steps of How the Greenhouse Effect Works?
- 1) The sun's Radiation Travels towards the earth.
- 2) About half of it is reflected or Absorbed by clouds in the atmosphere.
- 3) The rest then reaches the earth Where its absorbed by oceans and land.
- 4) The earth then releases heat back into space.
- 5) Some of this Heat Passes directly Through the atmosphere.
- 6) But most of it is captured and retained by greenhouse gases
47
Name 4 Human Causes of Climate Change?
- 1) Industry.
- 2) Agriculture.
- 3) Deforestation.
- 4) Cement Production
48
How does Industry affect Climate Change?
- Factories burn fossils fuels Which contribute to the greenhouse effect.
49
How Does Agriculture Affect Climate Change?
- Cows Fart and Release Methane Which can Contribute to the greenhouse effect.
50
How does Deforestation affect Climate Change?
- Plants Remove CO2 From the Atmosphere so when they are cut down They stop taking CO2.
51
How does Cement Production affect Climate Change?
- Cement is Made from Limestone Which Release CO2 Into the Atmosphere.
52
What's The Acronym to remember the 4 Global Impact of Climate Change?
- H - Health
- O - Oceans

- F -Food
53
How does Food Lead to global impacts of climate change?
- In Some Areas increased flooding will destroy crops and in other areas increased droughts will prevent crops from growing.
54
How does Health Lead to global impacts of climate change?
- Diseases Spread more easily because of mosquitos ( Malaria ) this is because of ideal temperature just right for mosquitoes.
55
How does Oceans Lead to global impacts of climate change?
- When ice in antarctica melts sea levels rise.
56
How does Water Lead to global impacts of climate change?
Precipitation Rain and Snow will increase meaning more freshwater is avialble.
57
Write a Definition of Mitigation and Adaptation?

59
Write a Description of Carbon Capture and where will it be trapped?
- Carbon capture refers to the process of capturing (CO₂) emissions from industrial processes, power plants, or from the atmosphere to prevent their release into the environment.
- The CO2 Emissions will be trapped Underground
60
Write 1 Pro and 1 Con of Carbon Capture?
- Pro: 90% Of carbon can be captured.

- Using water is an area that will need to change as summers et drier and water shortages are more common.
- Pro: Reduces the Demand for water.
- Con: it Uses lots of Enrgy.
62
Write a Description of Alternative energy production and give 1 Pro and 1 Con?
- We need more energy as countries develop using renewable energy is better for the environment.
- Pro:Produces Jobs in solar and wind production.
- Con:It Needs lots of sunlight and wind.
63
Write a Description of Change in agriculture system and Write 1 Con?
