Air pollution from the combustion of fossil fuels can lead to an increased occurrence of acid rain. If acid rain causes the water in a stream to become more acidic, what is the most likely effect on the geology of the stream bed?

A: The rocks in the stream bed weather at a slower rate

B: The population of fish in the stream increases

C: The population of the fish in the stream decreases

D: The rocks in the stream bed weather at a faster rate

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
