Question

Which statement best describes a long-term impact of volcanic eruptions?

a) Immediate cooling effect on the climate
b) Increased fertility of the soil
c) Long-term degradation of air quality
d) Preservation of wildlife habitats

Answer 1

Volcanic eruptions can cool the climate and have long-term impacts. An example is the 1783 eruption in Iceland that caused a haze-effect cooling and lower winter temperatures.

Step-by-step explanation:

Volcanic eruptions can have long-term impacts on the climate. They release gases and solids that can influence the climate over a few years. Generally, volcanic eruptions cool the climate by releasing particles that block out sunlight and lower global temperatures. An example of this is the 1783 eruption in Iceland, which led to a haze-effect cooling that caused some of the lowest average winter temperatures on record.
