|
The atmosphere (air) |
Mixture of gases which envelope the earth |
|
|
Low latitudes |
Warm air Sun is closer to equator More insulation 0-30° |
|
|
High latitudes |
Cold air At the poles |
|
|
Latitude |
Measures distance from north or south of equator |
|
|
Cool air sinks |
High pressure |
|
|
Warm air rises |
Low pressure |
|
|
Cyclone |
Warm air rises - clouds - rainfall - low pressure - 30-60° latitude |
|
|
Anticyclone |
Cold air sinks - clear Skye - dry weather - high pressure |
|
|
Polar cell |
Air cools and sinks - belt of high pressure - cold dry climate - 90° latitude |
|
|
Ferrel cell (pt.1) |
Cold polar air mixes with warmer air - rises - belt of low pressure - 60° latitude |
|
|
Ferrel cell (pt.2) |
Air Cools and sinks - belt of high pressure - as it sinks,warmer drier |
|
|
Hadley cell |
30-0° latitude - warm air rises - belt of low pressure - as air rises it cools - cloud form - precipitation |
|
|
Warmer climate |
Interglacial phase |
|
|
Cooler climate |
Glacial phase |
|
|
Ice cores |
Made of Layers(1year snowfall) Trapped bubbles CO2 - drill through core to measure CO2 |
|
|
Pliectocene |
Last major cold perid |
|
|
When did Pleistocene start and end |
Started 2.6mil years ago Ended 10,000 years ago |
|
|
Current warm phase |
Holocene |
|
|
Holocene and Pleistocene |
Quaternary period |
|
|
Quaternary period |
The period of geothermal time we are living in |
|
|
Warmest 10 year period on record |
2013-2022 |
|
|
Seasonal shifts |
Effect nesting and migrational patterns of wildlife |
|
|
3 greenhouse gases |
Nitrous oxide Methane Carbon dioxide |
|
|
What is an ice core |
Layers of ice built up over time 1 layer = 1 year |
|
|
How are ice cores used to measure climate change |
CO2 trapped in bubbles Measure the CO2 in each bubble |
|
|
Atmospheric gas concentration |
CO2 measured in ice cores |
|
|
Atmospheric gas concentration |
CO2 measured in ice cores |
|
|
3 examples of natural climate change evidence |
Ice core Tree rings Historical sources |
|
|
What would happen without natural greenhouse effect |
The planet would be to cold for humans to survive |
|
|
How do greenhouse gases heat up the planet |
Some long radiation is reflected of greenhouse gases back to earth - heating the earth up |
