In recent years, scientists have collected data on the extent of sea ice in the Arctic Ocean as shown in the graph. What additional 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

Option 2, or B

Explanation:

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.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

c is the answer to this question. altitude affects the weather because air molecules evaporate.
