Alarge volcanic eruption occurred spewing ash and other gases into the atmosphere. what is the most likely effect of the eruption on the carbon cycle?
a
decreased atmospheric carbon dioxide levels due to lower global temperatures
b
increased atmospheric carbon dioxide levels due to lower global photosynthesis rates
c
increased oceanic carbon dioxide levels due to falling soot(ash) pulling carbon dioxide into the water
d
decreased oceanic carbon dioxide levels due to water vapor absorbing heat and blocking the carbon dioxide from entering the oceans

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt

β’what conclusions can you make about the relationship between the volume of a gas and its temperature? β’ what conclusions can you make about the relationship between the volume of a gas and its pressure? β’ what possible variables have you not accounted for? as you did the procedures, is it possible that the atmospheric pressure may have changed? if it did change over the course of your experiment, then how would your results have been affected?
