Answer:
The recent drought in Russia caused an increase is WILDFIRES.
Step-by-step explanation:
The recent drought in Russia led to an increase in wildfires. Drought creates dry conditions, making vegetation more susceptible to catching fire. The lack of moisture in the soil also hampers firefighting efforts. Strong winds can further spread the fires. Drought does not directly cause flooding, tornadoes, or volcanic eruptions, as these are separate natural disasters with their own causes.
