what is the Quaternary period |
The most recent geological time period spanning from 2.6 million years ago to the present day |
|
|
Describe how climate has changed from the beginning of the quaternary period to the present day |
during the course of the period the global temperature has shifted between cold glass and your periods the last for around 100,000 years and warmer periods the last for around 10,000 years |
|
|
Why are ice cores a useful source of information about the past climate |
they can analyse the gases trapped in the layers of ice which can tell them what the temperature was each year |
|
|
How do you see ice positions provide evidence to climate change |
see ice formed around the polls in winter and melts it during the summer but observing the minimum and maximum amount they can tell how the ocean temperatures are changing |
|
|
why might data provided by Weather stations be unreliable as a record of global climate change |
as they’re only short term as they’ve only been reported from the 1850s |
|
|
why might data provided by Weather stations be unreliable as a record of global climate change |
as they’re only short term as they’ve only been reported from the 1850s |
|
|
describe how diary entries and paintings can give evidence of climate change |
Diaries can show what the climate was like in the past paintings of fairs and markets on frozen river sure that winters in Europe were regularly much colder 500 years ago that they are now |

|
|
what are Milankovitch cycles |
variations in the way the Earth moves around the sun |

variations in the way the Earth moves around the sun |
|
|
How do you Milan Cavitch cycles affect the Earth’s climate |
these cycles affects how far the Earth is from the Sun and the angle that the suns rays hit the Earth changing the amount of solar radiation that the Earth receives |

|
|
How much sun spots affect the Earth’s climate |
Some spots of cooler areas of the Sun surface which means solar output is reduced. This may cause the earths climate to become cooler in some areas |
|
|
Describe how volcanic activity might cause climate change |
some particles reflect the suns rays back out into space is a volcanic eruption |
|
|
What is the natural greenhouse effect |
gases in the atmosphere naturally acting like an insulating layer-they trap outgoing heat helping the Earth stay at the right temperature |
|
|
What is the natural greenhouse effect |
gases in the atmosphere naturally acting like an insulating layer-they trap outgoing heat helping the Earth stay at the right temperature |
|
|
name two greenhouse gases |
Carbon dioxide and methane |
|
|
What is the enhanced greenhouse effect |
Human activities that cause global warming by making the greenhouse effect stronger |
|
|
Give full ways that human activities increase the concentration of greenhouse gases in the atmosphere |
farming, cement production, burning fossil fuels and deforestation |
|
|
What affect might increasing temperatures have a polar habitats |
warmer temperatures would cause the glaciers to shrink and ice sheets to melt this would cause a rise in sealevel leading to loss of polar habitats |
|
|
How might species distribution be affected by climate change |
Some species will now be fined and higher latitudes due to warming temperatures. Some habitats are being damaged or destroyed due to climate change leading to them becoming extinct |
|
|
Outline possible global economic impacts of extreme weather |
more money would have to be spent on predicting extreme weather events reducing the impact and rebuilding after them |
|
|
Describe one possible economic impact of climate change on areas of permafrost |
rising temperatures are causing areas of permafrost to melt this could lead to collapse of buildings which have been built on it |
|
|
give one possible social impact of sealevel rise |
low-lying coastal areas could be lost to the sea or floods so often they become impossible to inhabit |
|
|
Give one way that climate change might have an impact on health |
lower crop yields could increase malnutrition ill-health and death from starvation particularly in lower latitudes |
|
|
give two ways that extreme weather events in the UK might be affected by climate change |
Droughts are expected to be more frequent in southern England Flooding will become more common due to increased rainfall and sealevel rise |
|
|
Give one possible environmental impact of sealevel rise in the UK |
It will lead to loss of habitats |
|
|
How might climate change affect tourism in the UK |
warmer weather could boost the tourist industry if more people decide to do a holiday in the UK |
|
|
outline the possible economic impact of climate change on agriculture in the UK |
temperature increase and a longer growing season may increase productivity of some crops New crops can adapt to warmer climates which can now be grown in southern England |
|
|
How much are UK fishing industry be affected by climate change |
More extreme UK weather conditions could push that she infrastructure at risk from storm damage Fisherman’s livelihoods could be affected by changing fish populations and specie standing UK waters |
|
|
Describe one social impact of climate change in the UK |
that’s from cold related illness might decrease but health services may have to treat more heat related illnesses |
