In recent years, scientists have collected data on the extent of sea ice in the Arctic Ocean as shown in the graph. What additio
nal data could be used to support or refute the theory of global climate change? O A graph providing data on daily temperature fluctuations from 1980 to 2010
O A graph providing data on average global temperatures from 1980 to 2010
O A graph showing monthly fluctuations in sea ice extent for each year 1980 to 2010
O A graph showing yearly fluctuations in sea ice extent for each year 1980 to 2010
The most practical data would be global temperatures during the 37+ year time period to coincide with the thinning sea ice. Option #1 is far too broad to include (daily), as is option #3 (monthly). The last option is basically proposing to duplicate what the graph already shows.
1. ridges and trenches (either answer is acceptable)
2. mid-atlanitc
3. subduction zone
4. molten
5. oceanic trenches
Explain:
6. Rocks in the ocean eventually get subducted back into earths mantle due to slab pull. New rocks form at mid-ocean ridges as ridge forces two plates to diverge.
