Climate Change
any change in the Earth’s climate, including global trends in warming, cooling, precipitation, wind directions, and other related measures.
Global Warming:
An increase in the average temperature of Earth’s surface.
Interglacials
Warm periods that occur during ice ages.
Ice Ages:
Lasting cold periods when glaciers and ice sheets cover much of the Earth.
Greenhouse gases:
Water vapor, carbon dioxide, methane, nitrous oxide,
How does a volcanic eruption effect the carbon cycle
The short-term effect is that sulfur dioxide and ash are released, blocking the sun and causing the Earth to cool down. The sulfur has a high albedo, so it is very reflective. This also limits plant growth since there is no sunlight for photosynthesis. The long-term effect is that carbon dioxide is released, adding to the buildup of carbon dioxide in the atmosphere.
What does the increase in ultraviolet tell us?
The Ozone layer is thinning and more UV Radiation is getting through the atmosphere.
The thickness and thinning of ice caps tell us____
climate change is occuring
Coral Bleaching
When ocean temperature increases, coral releases algae that block the sun from other producers. The other producers eventually die off leading to the downfall of the food web
Deforestation Impact
More carbon that the trees should have absorbed will be left in the atmosphere.
how do seasons impact the carbon cycle with producers?
During the growing seasons more plants will do photosynthesis and more carbon will be abosorbed
Where does carbon enter food webs first
Producers
3 ways carbon is fast cycled
cellular respiration
decomposition
photosynthesis
in what sphere does fast cycling occur
bio sphere
slow cycling ways
volcanic activity
formation of sedimentary rocks
weathering
greatest output on earth of greenhouse gasses
automobiles
burning of fossil fuels
