Climate Flashcards
High humidity makes the air feel?
Hotter/Warmer
What causes weather?
Interactions between water and air on Earth and Suns energy
What is climate?
The average of the weather in a region over a long period of time
What are proxy records?
Stored information that can be measured to give clues to what the climate was like in the past
Who studied long term cycles of climate change and calculated Earths orbit in 3 ways?
M. Milankovitch
Define interglacial period
Time between ice ages when Earth warms up
Boulders came from what
Glaciers
What is a heat sink
A reservoir that absorbs and stores thermal energy
Heat sink example
The ocean
The greenhouse effect:
The way gases in the atmosphere trap heat from the sun
Average global temperature
15°C
List greenhouse gases
Water vapour (H2O), carbon dioxide (CO2), methane, nitrous oxide, and tropospheric ozone
Ozone prevents?
Most of harmful energy
The suns radiation is..
30% reflected, 70% absorbed
Atmosphere is?
The layers of gases surrounding the Earth
Examples of permanent ice
Glaciers, mountaintops, permafrost
Rocks, dust, and gases spews high into the atmosphere during what?
Volcanic eruptions
3 ways to calculate earths orbit
Eccentricity (shape of orbit), Tilt, and Pression of tilt (wobble)
Six proxy records
Ice cores, tree rings, coral reef, rock, ocean sediment, and caves
