A group of scientists predicts that Earth's oceans will be able to take up more carbon dioxide as atmospheric carbon dioxide levels increase and the atmosphere warms. Which of these statements about the solubility of gases in ocean water would lead you to question this prediction? OPTIONS:
- Solubility decreases with an increase in salinity.
- Solubility decreases with an increase in temperature.
- Solubility increases with an increase in pressure.
- Solubility increases with an increase in pH.
A: Solubility decreases with an increase in temperature.

When a cold front moves over a land region that has warm, moist air, a transfer of energy occurs. Cold air sinks and pushes warmer air upward. As energy is removed from the air, which change will most likely take place? OPTIONS:
- Ozone in the atmosphere will decrease.
- Less ultraviolet radiation will reach the land.
- More water will be absorbed from the area lakes.
- Water in the atmosphere will undergo a phase change.
A:
Water in the atmosphere will undergo a phase change.
