Final answer:
Hurricane frequency is likely to increase due to global warming, as higher sea surface temperatures can enhance the energy available for storms, leading to more frequent and intense hurricanes. Earthquakes, volcanic eruptions, and tsunamis are primarily driven by tectonic activities, not by climate.
Step-by-step explanation:
The question asks which hazards might increase due to global warming. Among the options provided, the most likely to occur is an increase in hurricane frequency. This is supported by scientific research that links global average air and ocean temperatures to the intensity of precipitation events and the behavior of tropical storms.Regarding the increase in hurricane frequency, scientists have observed that because global warming leads to higher sea surface temperatures, it can enhance the energy available for storms, potentially leading to more frequent and more intense hurricanes.Although earthquakes, volcanic eruptions, and tsunamis are also serious natural disasters, their frequency and intensity are not primarily influenced by changes in Earth's climate. Instead, tectonic activities such as the movement of the Earth's plates and volcanic activity power these events. Nonetheless, secondary effects, such as the weight of large amounts of ice melting from glaciers potentially influencing seismic activity, might be linked indirectly to climate change, but the primary triggers are geologic rather than meteorological.
