What's up?
What layer of the atmosphere do we live in?
Troposphere
Why do we have water vapor in our atmosphere?
Weather
What gas is closely correlated to temperature throughout time?
CO2
CO2, methane, H2O, N2O
What is happening to glaciers because of increased CO2 levels in the atmosphere?
They are melting & receding.
What layer of the atmosphere has the most water vapor?
Troposphere
Name a gas responsible for keeping our Earth warm
CO2, H2O, Methane
How can we tell what CO2 levels were like before people were measuring it?
Ice cores
Which common greenhouse gas is more efficient at absorbing heat and is in frozen form at the bottom of the ocean in the Arctic.
Methane
Why are corals being bleached?
Ocean temperatures are rising.
What is the second most abundant gas in the atmosphere?
Oxygen
What gas protects us from harmful UV radiation?
O3 (Ozone)
Why are ice cores useful for telling us the CO2 level in the past?
There is old atmosphere preserved as bubbles in the ice.
What is the reason we have natural climate change? Name 3 reasons.
Volcanoes, Sun cycles, Milankovitch cycles.
What is a consequence of our ice caps melting?
Sea levels rising.
What is the reason for Nitrogen in the atmosphere?
Buffer to prevent combustion.
What are the two rolls of O2 in the atmosphere?
Combustion, breathing
Which oxygen isotope is most abundant in ocean water during interglacial (warm) periods?
O-16
What is the type of radiation absorbed into the Earth? be specific.
Shortwave Infrared Radiation
Why are sea shells dissolving?
Where is one place we can naturally get CO2 into the atmosphere besides respiration?
Why would a shell formed in a glacial period have proportionally more O-18 than one formed in an interglacial period?
DAILY DOUBLE:
Draw a diagram of the greenhouse effect. Label these parts:
Longwave Infrared Radiation, Shortwave Infrared Radiation, what happens to each of these radiation, greenhouse gasses involved.
I will check.
Why would we see more hurricanes if CO2 levels continue to rise in the atmosphere?
Oceans will warm. Warm ocean water feeds hurricane storms.
