BEFORE WE START: 
Reading and making a graph

Remember:
SOURCES go UP into the atmosphere.
SINKS go DOWN into the ground and water.

Which season had the lowest CO2 levels and WHY?

Which are the 3 SINKS of CO2?

respiration and decomposition

volcanoes erupting

photosynthesis by plankton

dissolving INTO water and rock

deforestation and wildfires

photosynthesis by trees

dissolving OUT OF water and rock

burning fossil fuels

Which are the 5 SOURCES of CO2?

dissolving INTO water and rock

photosynthesis by plankton

volcanoes erupting

burning fossil fuels

deforestation and wildfires

photosynthesis by trees

dissolving OUT OF water and rock

respiration and decomposition

What does it mean to have more sources than sinks of CO2? 

there's too much CO2 in the air

there's too much CO2 in the land and water

What MOLECULE of matter was measured with all this data? 

CH4

C6H12O6

CO2

H2O

O2

WHERE was this data collected from? (Click on "e" from page 1)

Columbia University in NYC

Mount Loa in Hawaii

from a satellite up in space

Mount St. Helens in Oregon

At a weather station in the Bahamas

Are the seasons the same in the Northern and Southern Hemispheres? (yes/no and why)

yes

no

bc the rotation of earth allows daytime and nighttime

bc the tilt of the earth allows one hemisphere to be getting more or less sun

bc the Earth revolves around the sun so its always hot by the equator

Which hemisphere has more LAND and therefore more CO2 being released from it into the atmosphere?

North

South

Would these 4 things be a SOURCE or a SINK of carbon?

sink

source

Which 2 patterns (trends) did you see in the data from the graphs?

the CO2 decreased in the fall and increased in the spring of each year

the CO2 decreased over 50 years 

the CO2 increased over 50 years

the CO2 increased in the fall and decreased in the spring of each year

What do trees, plants, algae, phytoplankton, and cyanobacteria do with CO2?

release it

use it
