evs final part 3

steady state

when sinks and sources are equal

residence time

amount of time spent in reservoir

residence time=total amount of substance in res/flux(rate of flow in or out)

Understand the importance of stratospheric ozone, and how a global response has successfully addressed decreases caused by human impact

Stratospheric ozone protects life on Earth by absorbing harmful ultraviolet radiation.

Explain some ways we know about Earth’s past climates

Ice cores- traps tiny bubbles of air before compressed into ice, they measure the exact concentration of CO2

fossils

tree rings

sediment cores

geologic landforms- caves, moraines, glacial scratches

Understand and explain what factors have been responsible for the dramatic changes we have seen in climate over the history of the earth

Factors include volcanic eruptions, changes in solar radiation, and human activities such as industrialization

Understand and explain the association of global temperature with sea level 

global temperature is associated with sea level rise, as warmer temperatures lead to melting ice and thermal expansion of water

What kinds of evidence do we have that our climate is currently changing? 

Evidence includes rising global temperatures, shrinking ice sheets, and increased frequency of extreme weather events.

What are the primary drivers of our current change in climate? How is our current change in climate similar to/ different from past changes in Earth’s climate? 

Evidence includes rising global temperatures, shrinking ice sheets, and increased frequency of extreme weather events.

What types of things can be done to reduce/mitigate our current changes in climate, both on an individual level and on a societal level?

Actions include reducing energy consumption, using public transportation, recycling, and supporting sustainable practices.
