Choose the option with the biggest contributors to the natural greenhouse effect.
Carbon dioxide, Methane, Water vapor
A location’s climate can be affected by all of the following, except:
The wildlife
Name all of the GHG’s
Carbon Dioxide
Methane
Nitrous Oxide
Water vapor
Ozone
Why are algae and plants a great carbon sink?
As algae grows it removes carbon dioxide from the atmosphere and converts it into biomass and oxygen via photosynthesis.
How is the greenhouse effect responsible for keeping the planet warm?
They absorb the sun’s heat that radiates from the earth’s surface, trap it in the atmosphere and prevent it from escaping to space
What are UV rays and what does the atmosphere does to them?
UV rays are divided into 3 regions called UVA, UVB, UVC. As sunlight passes through all UVC and UVB is absorbed by ozone, water vapor, oxygen and carbon dioxide.
