Answer:
Volcanoes can have very serious effects on the environment around them when they erupt. Buildings are destroyed and people are made homeless. People are killed. Clouds of ash cover plants making them inedible. Dust causes pneumonia and illnesses to the survivors. Dark skies, severe winds and heavy rains may follow an eruption for months afterwards.
Step-by-step explanation:
Gases and solids injected into the stratosphere circled the globe for three weeks. Volcanic eruptions of this magnitude can impact global climate, reducing the amount of solar radiation reaching the Earth's surface, lowering temperatures in the troposphere, and changing atmospheric circulation patterns.
