Explain how Earth’s spheres may be affected by the droughts brought on by El Niño.

Answer:

Droughts caused by El Niño can reduce water in rivers, lakes, groundwater, and soil, affecting the hydrosphere. Dry soil can erode and become more vulnerable to wildfires, affecting the geosphere. Plants, animals, and people may lose water and food, harming the biosphere. The atmosphere may become hotter and drier, increasing dust and fire risk.
