If the half-life is 80,000 years, then 240,000 years would be equivalent to three half-lives. In other words, the initial amount of the radioactive calcium-41 would have been reduced in half three times over. Mathematically, this can expressed as
calcium-41 remaining = initial mass of calcium-41 × (0.5)³.
Since we are given the initial mass of calcium-41, the amount of calcium-41 remaining after 240,000 years would be:
60 μg × (0.5)³ = 7.5 μg, or 7.5 micrograms.

An increase in the concentration of greenhouse gases, like carbon dioxide, in the atmosphere can increase the temperature on Earth. How would such an increase in temperature most likely affect Earth's water cycle?
Answer:
Global warming intensifies water cycle
Explanation:
Global warming can dramatically intensify the water cycle because this phenomenon is associated with an increase in temperature, thereby a higher amount of water is evaporated into the air and a higher amount of ice is melted at the poles. Warmer atmospheric air will have a higher amount of water vapor, increasing the frequency and intensity of rainstorms. In consequence, global warming can significantly increase the probability of flooding in coastal communities.
